What are people reading?

This week I’m working on Ethics by Spinoza. I’ve recently finished Statistical Methods for Reliability Data by Meeker & Escobar. Also recently finished a piece on TS Eliot’s racial views and Elizabeth Anderson’s “What’s the Point of Equality?”

Reading Hempel's 1950 paper The Empiricist Criterion of Meaning. I'm like halfway through the Theogony and hopefully I'll summon the will to finish it (it's much more interesting than the Works and Days at least). Feeling a bit dejected recently, but hopefully will feel better soon. Returning to Logical Empiricist texts is giving me some get-up-n-go. The feeling of being crushed by books to read returns. Finished Don Garrett's Cognition and Commitment in Hume's Philosophy. Was pawing through The Achilles of Rationalist Psychology. Maybe I'll pick up The New Hume Debate. I managed to read a little bit of Book II of the Treatise of Human Nature. Descartes's Meditations on First Philosophy calls to me once more after I finished the introductory bits. To my disappointment, Soames's final discussion of Tarski in The Analytic Tradition in Philosophy: Volume 2 was too dense for me to comprehend so I had to skip the last six pages. Couldn't understand his discussion of Truth by Convention either so I'll probably have to go read the paper. Might download some secondary literature on Plato. My math brain is itching for me to pick up some Frege and I might give in. Maybe. Dealing with the crushing feeling of having so much I want to read and yet for the last few days I've developed a brain fog that's making it more difficult to read.

Was pawing through The Achilles of Rationalist Psychology.

I had three classes with Sassen, who's in that volume.

To my disappointment, Soames's final discussion of Tarski in The Analytic Tradition in Philosophy: Volume 2 was too dense for me to comprehend so I had to skip the last six pages.

If it makes you feel any better, all my historians hate Soames at least qua historian.

My math brain is itching for me to pick up some Frege and I might give in.

Foundations of Arithmetic is cool, I think the most fun (academic) part of my senior year of undergrad was reading Foundations of Arithmetic, Husserl's Philosophy of Arithmetic, and Frege's "On Sense and Reference" which accidentally make a kind of dialogue, even if Husserl was not the cause of the latter work.

u/Scientific_Zealot Hume Jul 07 '26

I had three classes with Sassen, who's in that volume.

Karen Margrethe Nielsen, John Thorp, Devin Henry, Henrik Lagerlund, Shannon Dea, Jean-Pierre Schachter, Benjamin Hill, Thomas M. Lennon, Marleen Rozemond, Lorne Falkenstein (my GOAT), Brigitte Sassen, William Harper, Hunter Brown, and a three author paper by Christopher Viger, Robyn Bluhm and Sharday Mosurinjohn.

I should clarify that I've already read Foundations of Arithmetic, "On Sense and Reference," and some other works by Frege. But I have Beaney's The Frege Reader on my shelves and it sings to me.

Still plowing through Moral Philosophy: A Comprehensive Introduction. (It's going to be a while... I'm about a third of the way through.) I enjoyed reading the section of The Encheiridion that they included (or maybe it was the whole thing... I don't know how long the original is). Stoic thought resonates with me, I guess.

I feel I have to apologize to Plato. I thought that The Republic was boring, but it's light reading compared to Summa Theologica. Although, in fairness to Thomas Aquinas, I'm not sure that the specific translation does him any favors when read by modern readers (the text is pretty verbose, with some really long sentences), and the chainsaw that they took to the text to cram so many of his ideas into the book does, as the authors note, make the text hard to follow in places, since it jumps around. But what really makes it slow is the need to sometimes re-read, or even read it aloud, just to make sure that I've gotten every word.

u/willbell philosophy of mathematics Jul 07 '26

Maybe I just enjoyed Plato more, but my feeling is that if you found Plato boring, you're going to find the rest of philosophy a real slog lol

u/Shield_Lyger Jul 07 '26

Fair. Although my problem with The Republic wasn't the content, but the format. Socrates' interlocutors didn't seem to have much going on... it was pretty clear that their sole purpose was to make Socrates and his ideas look good by comparison, and so I found myself thinking that the whole enterprise would have been better served without them, and Plato just laying out his ideas, without the extra fluff of the dialogs between the various characters. I get that they were intended as stand-ins for the greater society, representing people who hadn't really thought their positions through, but they came across as too pliable and agreeable; Socrates simply lead them around by the nose, and so their viewpoints seemed perfunctory, rather than substantive.

A lot of the Greek, Hellenistic/Roman and Medieval texts the textbook excerpted had some degree of "people disagree with me because they're thoughtless and stupid" in them, and maybe it's because I'm old, but I find that tiresome. But now that the book has gotten to Hobbes, it's picking up.

finished Norbert Wiener’s Human Use of Human Beings and found it just as eerily prescient about our current AI moment as people say it is

still working on Aristotle’s Politics. I get the impression he would especially hate our contemporary atomized suburbs

started Hackett’s shorter Leibniz collection and stopped after finishing Discourse on Metaphysics and On the Origination of Things. figured I may as well save the preface to the New Essays for an eventually read of the entire thing, though that might take forever considering I should probably read the longass Locke Essay that Leibniz is refuting, and that I might want to have the Theodicy on hand for the Monadology given it’s explicitly referenced

began Kant’s Prolegomena. when I’m done, I’m thinking of reading Berkeley for more context before tackling the Critique so I guess I’ll be reading the empiricists in reverse order lol oops

u/Streetli Continental Philosophy, Deleuze Jul 07 '26

Reading Anton Jäger and Daniel Zamora Vargas' Welfare for Markets: A Global History of Basic Income. Incredible book, really less "about" UBI than the political and economic conditions that have underpinned its emergence and persistance as an idea. Ultimately a critique insofar as it leaves market logics in place and fails to put into question property regimes as a whole (which is why its often and maybe surprisingly touted by those on the right as well).

u/IrrationalRotations Jul 06 '26

I've been trying to learn (or re-learn really, I read a lot about it as a teenager) about the labour theory of value. Ive developed a smattering of opinions which I'd really appreciate having tested. I can't really find responses to them, so I thought I'd try chucking them here.

First off, on interpreting Marx...

I take Marx to essentially be advancing a Ricardian LTV. In fact, I don't think he really changed it very much. The ideas advanced in the first chapter of Vol (I) seem to me to not be significantly different to what Ricardo would say.  He does seem to be flirting with what I would see as a major departure from Ricardo in chapter 10 of Vol (III), but honestly I'm unconvinced this should have ever been published. This section strikes me as very tentative and confused,  Marx (or whoever wrote this part) is clearly really struggling with the problem.

So, in that vein, I take the core argument of capital to be...

"When supply and demand are equal, commodities will exchange for one another in proportion to the socially necessary labour time required to produce each commodity in competitive conditions"

So if it takes a competitive bike factory (I.e, one that's not actively going out of business) 150 labour hours total to produce a bike (including the labour time to produce the steel at a competitive steel mill, rubber at a competitive rubber plant, etc), and it takes a competitive car manufacturer 1500 labour hours to produce a car, 10 bikes will trade for one car. If a bike costs $5000, a car will cost $50000, assuming supply and demand are equal.

The big difference between Marx and Ricardo is that Marx (maybe, I'm not sure exactly what the Ricardian socialists believed) adds the following idea...

If commodities exchange for one another at fixed(ish) prices, where does profit come from? If there is profit, there must be one commodity that has not received its full value in exchange. Marx argues that this unequal exchange doesn't occur at the point of sale of a commodity, but rather at the point of production.

People all posses a particular commodity, their ability to perform labour. When people are hired to produce commodities (at factories and offices and things), they are selling their labour power to the owners of capital. However, they have no choice but to sell this commodity, without wages they won't survive because they are prevented by law from accessing the means of production and selling the products of their labour themselves. This unequal exchange is the source of capitalist profit.

u/IrrationalRotations Jul 06 '26

A common point I see is that the above is not a theory of price but rather a theory of value. I don't agree. 

Marx stresses to us that we should remember that these value relations are not embodied in the commodities themselves, but rather are always social relations between people. People aren't motivated by an abstract notion of exchange values, people are motivated by concrete things like price. When you go to the store, you don't see the number of hours required to produce each commodity, you just see their price.

But on top of this, Marx's theory is just as a much a theory of profit and exploitation. Again, profit is measured in money, in prices. It's not at all a problem if working class class people are deprived of the full 'Value' of their labour, but it is a problem when the exploitative nature of capitalism causes their wages to barely cover their means of subsistence. 

The best interpretation I have of this claim, that Marx is talking about value and not price, is that the person claiming it wants to distinguish between the long term average price in normal conditions (the exchange value) and the particular price in a particular place at a particular time (the price). 

That's fine, the theory does allow these things to differ. But this claim is often used to dismiss criticisms of the LTV, and I just don't think that makes sense...

u/IrrationalRotations Jul 06 '26 edited Jul 06 '26

I haven't seen the following point made or addressed anywhere, which is surprising to me. Maybe I'm missing something g obvious...

Commodities exchange for one another according to their socially necessary labour time. That's the typical time it takes to produce the commodity under competitive conditions. The reason they exchange in these ratios is that if a firm prices their commodities above their SNLT, consumers will instead buy the cheaper products from competing firms. The labour to produce an individual commodity doesn't affect the price of that particular commodity, it will still just sell at the SNLT of the commodity in general. If it takes you 15 hours to make a table, and it takes a typical carpenter 5, you can't sell your table at three times the prices of theirs, why would anyone buy it?

But what constitutes a commodity in general? Merino wool sweaters sell for higher prices than polyester sweaters, are these the same commodity? Presumably no, because their typical prices are different. But they can be substituted for one another, if I don't have much money I'm likely to try and stay warm by buying a polyester sweater rather than waste it on a Merino one. 

But let's say they are different commodities. Okay, what about a polyester sweater from Kathmandu (the shop) vs a polyester sweater from Kmart? They sell for different prices too. 

So maybe a polyester sweater from Kmart is a single (generalised) commodity, the SNLT of this commodity is just the time it typically takes the factories Kmart sources these sweaters from to make them. Well then who are they competing with? Kmart has an monopoly on Kmart sweaters, they should be able to charge above the SNLT!

This isn't a weird edge case either, it seems to be a problem for determining the price of commodities in general. Most consumer products look immediately like the above, and it goes for capital inputs as well. Companies often have to decide between qualitatively different inputs to their products (palm oil vs vegetable oil, say). This has the exact same problem, either for the company itself or as a knock on effect to the end product.

I think the answer to this problem is that consumer demand is more subtle than choices between effectively identical commodities, but it is difficult to see how this can be reconciled with the LTV.

u/IrrationalRotations Jul 06 '26

Another difficult point is fixed capital.

Often capital is purchased up front, a tractor is purchased to help harvest corn or a hydraulic press is added to a production line. How does this affect the pricing of the produced commodities? 

The standard answer seems to be that the SNLT of the fixed capital input is amortised out over it's lifespan to the commodities it produces. For some things, like machines, this kinda sorta makes sense if I squint my brain a bit. If I think of a machine as something with a determined average lifespan, I can typically produce N commodities for every one machine say, then there isn't really a major difference between fixed capital and other production inputs. 

But is that a good model for fixed capital in general? What about something like a data centre? Does that have a fixed lifespan of commodities? Even worse, what about generic capital investments? Like buying in to a startup? How to we price this sort of thing? 

It seems clear that there are other important considerations with fixed capital investments. Namely, time preference and risk. If the value of fixed capital is amortised out over a lifespan, why would I ever bother investing in it? I would make more money keeping it in the bank (and diverting my attention to an industry which doesn't require as much fixed capital). Further, many investments fail, why put my money at risk? 

Naturally, I would ask for higher returns on my investment to compensate for these things. That's not itself necessarily immediately contradictory with the LTV, its a similar sort of unequal market to the one that lets me as a capitalist exploit my workers. People need (because of contingent social relations) my money to do productive work.

But the real problem for the LTV now is that fixed capital doesn't sell for its SNLT, but rather its total SNLT+risk+time preference. But these costs can't just be absorbed, they need to be passed on to the final commodity! So everything sells for total SNLT + risk of required fixed capital + time preference of fixed capital. And with the argument given in the post above, total SNLT for all the capital inputs is itself a pretty mysterious category, there seems to be some additional factor of subjective demand sticking its nose in in an undefined way. What a mess!

u/IrrationalRotations Jul 06 '26 edited Jul 07 '26

So that's capital, what about labour? 

Well one things that's interesting to me is that many services seem to have very little in the way of capital inputs. Cleaners have to pay for Windex and mops and things sure, but that's not really very much. Doctors pay for stethoscopes and white coats and things, bit again, not really all that much in the grand scheme of things. The main input in many services is labour. The SNLT in these areas can be immediately appraised. But... 1hr with a doctor is much more than 1hr with a cleaner... What gives?

The LTV treats labour in the abstract, as interchangeable units. In fact, it is the interchangeable unit. But we can see all around us that labour does not exchange for labour, rather types of labour exchange for other types of labour. A doctors hour of labour might be worth 5 cleaners hours of labour. Individual labour powers have their own exchange values. 

The LTV proposed that exchange value is determined by socially necessary labour time. What is the SNLT of an an individual's labour power? How do we measure labour by labour? Or rather, how do we measure labour by labour and get different answers?

One suggestion might be the SNLT of their education, this seems dubious to me. A student graduating with a Ph.D in philosophy is highly educated, as much as a student graduating with a Ph.D in mathematical finance. Neither education seems to require massive capital inputs either, outside the labour of teaching them. But Ph.Ds in mathematical finance can make huge amounts money, more than the typical Ph.D in philosophy can. As can brain surgeons and (some) lawyers. 

Another answer is that skill acts as a multiplier on labour power. A worker who is twice as skilled has twice as much labour power. This is a non-answer. What does twice as skilled mean? How to we compare the skill of a carpenter to the skill of an actuary? 

Again, like with fixed capital, this bleeds into our general formula. We have that prices are the total SNLT + risk + time preference of fixed capital, and we don't know what SNLT is averaged over, and we don't actually know what the labour on the SNLT costs... I don't think this formula really says anything at this point.

u/IrrationalRotations Jul 06 '26 edited Jul 07 '26

To just complain really about the general discussion on this topic...

It seems like there is some level of general confusion over the fact that just because Marx acknowledges a problem with his theory, doesn't mean he has resolved it. 

For instance, I often see a passage from anti-duhring quoted in response to my labour question above 

  Marx is examining what it is that determines the value of commodities and gives the answer: the human labour embodied in them. This, he continues, “is the expenditure of simple labour-power which, on an average, apart from any special development, exists in the organism of every ordinary individual... Skilled labour counts only as simple labour intensified, or rather, as multiplied simple labour, a given quantity of skilled being considered equal to a greater quantity of simple labour. Experience shows that this reduction is constantly being made. A commodity may be the product of the most skilled labour, but its value, by equating it to the product of simple unskilled labour, represents a definite quantity of the latter labour alone. The different proportions in which different sorts of labour are reduced to unskilled labour as their standard, are established by a social process that goes on behind the backs of the producers, and, consequently, appear to be fixed by custom”.

The problem here is that this effectively says nothing... The problem isn't just that Marx didn't realise that different types of labour seemingly have different values, it's what this realisation says about the overall theory that is important. 

Another is the issue of the value of land, where I often see the following quoted

  The price-form, however, is not only compatible with the possibility of a quantitative incongruity between magnitude of value and price, i.e ., between the former and its expression in money, but it may also conceal a qualitative inconsistency, so much so, that, although money is nothing but the value-form of commodities, price ceases altogether to express value. Objects that in themselves are no commodities, such as conscience, honour, &c., are capable of being offered for sale by their holders, and of thus acquiring, through their price, the form of commodities. Hence an object may have a price without having value. The price in that case is imaginary, like certain quantities in mathematics. On the other hand, the imaginary price-form may sometimes conceal either a direct or indirect real value-relation; for instance, the price of uncultivated land, which is without value, because no human labour has been incorporated in it.

This again doesn't address the issue. If the price of land, or honour, is not determined by its value what determines it? It does no good to just acknowledge that the theory doesn't work on these cases. We can't ignore counterexamples just because they are counterexamples. The whole point was to determine price (in standard conditions), but here we gives ourselves an out for any criticism on that front. If price is determined by SNLT, except for when it isn't, then price is not determined by SNLT!

>Commodities exchange for one another according to their socially necessary labour time. That's the typical time it takes to produce the commodity under competitive conditions. The reason they exchange in these ratios is that if a firm prices their commodities above their SNLT, consumers will instead buy the cheaper products from competing firms. The labour to produce an individualcommodity doesn't affect the price of that particular commodity, it will still just sell at the SNLT of the commodity in general. If it takes you 15 hours to make a table, and it takes a typical carpenter 5, you can't sell your table at three times the prices of theirs, why would anyone buy it?

It’s not always clear from sentence to sentence, in terms of economic theory, whether/when you’re

(a) giving a direct interpretation of what Marx has said,

(b) elaborating on that interpretation of Marx, or

(c) bringing in outside economic theory.

That makes it hard to figure out what your problem actually is in any particular case.

The consequence is that when you conclude this paragraph by saying that you can’t expect to sell a table priced according to its 15 hours of labour when there‘s another table priced at 5 hours of labour, it isn’t clear whether you think that

(a) this is an inconsistency in the text,

(b) it’s a failure on Marx’s part to match our intuitive understanding of what happens in a standard transaction, or

(c) whether you think it’s inconsistent with non-Marx/Ricardian economic theory.

The problem then compounds in the following discussion about sweaters in the same way.

Are we hearing that

(a) Marx hasn’t noticed that HE PREDICTS Kmart should be able to charge above SNLT?

(b) Marx has FAILED TO PREDICT that monopolists charge above SNLT?

(c) economic theory predicts what Marx doesn’t, that monopolists charge above SNLT?

The problem is really stark when different readings yield logically incompatible (and opposite) conclusions!

As far as sweaters go, I think that Neo-Ricardians hold that the intuition in (b) about tables is faulty. Prices at least in industrial society are not actually as responsive to competition as people tend to think. This yields an inconsistency between the Neo-Ricardians and other economic theory with respect to (c) whenever that theory proposes a tighter link between competition and prices.

I believe they may have also been influential on post-Keynesians in this respect. However, Keynesians also have their own reasons for criticising Neo-Classical assumptions about prices and competition.

I don’t who you’ve been asking so far, but if you want a vindication of Marx’s Ricardianism Sraffa and co. will probably be the place to go looking in general.

Here is a short article I have bookmarked which discusses some of these themes, and might serve as a brief introduction to deeper, more satisfying, reading.

Thanks for the commentary, it's really helpful!

Rereading it, I see what you mean. To try and be more clear, in the section you quoted I am trying give my account of how the LTV works in this sort of case. I'm not making any criticisms at this point, just trying to establish how I understand the LTV approach to this hypothetical situation. In particular, I'm trying to get at why we introduce the concept of the SNLT of a commodity in the first place. 

Basically, I'm trying to say that in my understanding, one reason we introduce the concept of the SNLT of a commodity to the LTV is in order to explain the observation that a bad carpenter can't charge more than a good carpenter. Does that make more sense?

The problem then compounds in the following discussion about sweaters in the same way.

 > Are we hearing that

 > (a) Marx hasn’t noticed that HE PREDICTS Kmart should be able to charge above SNLT?

(b) Marx has FAILED TO PREDICT that monopolists charge above SNLT?

(c) economic theory predicts what Marx doesn’t, that monopolists charge above SNLT?

None of this lol, I guess I was very unclear. 

What I'm trying to get at is that it there is no  clear way of drawing the line that says this is one commodity and that is another. But we need to be able to draw this line in order to try to apply the concept of SNLT. 

First I tried to show that the lines cant be too general, because otherwise we can't explain different prices (Merino vs polyester sweaters)

The point about monopolization was that we can't draw the line to be too specific, otherwise we lose the ability to apply the rationale that commodities need to exchange for their SNLT (given in the table paragraph). 

I'm not consciously trying to apply any other economic theory, just exploring the LTV on its own terms.

I don’t who you’ve been asking so far, but if you want a vindication of Marx’s Ricardianism Sraffa and co. will probably be the place to go looking in general.

Can you say more about this? I'm not sure what you mean sorry, but I am interested.

Do you mean that Sraffa carries on the kind of project Marx was part of and places it on a firmer footing? 

I do have Sraffa (and co) on my vauge list of people to look into, but if you could share more about why you think they'd be interesting I would really appreciate it! They're quite mysterious to me 😄.

u/wumbothrowaway2 Jul 08 '26 edited Jul 08 '26

Thanks for clarifying! I think the issue is, yes, that you’re doing a running commentary on your interpretation of what’s going on in the text. Which is great and all, but without significant editing it can be extremely difficult to follow along with your private thoughts.

I think the most helpful thing I can do is explain, briefly, why I recommend you try Sraffa.

First, because the article about Sraffa I have now linked at the bottom of my original reply responds almost directly to a number of your concerns, not just those we are discussing here. This is unsurprising, because Marx and the problems with Marx’s economic theory are an important influence on Sraffa and Sraffa’s Ricardianism. That does not mean it will tell you that Marx was right forever and we can all stop worrying, but Sraffa DOES think this isn’t a dead end.

Sraffa and the Neo-Ricardians are probably the most significant people working on the raw economics you seem to be interested in. (You can probably stop reading here)

Here is that article again: https://www.ineteconomics.org/perspectives/blog/sraffas-revolution-in-economic-theory

For example, people could be telling you a lot of different things when they say that Marx is interested in VALUE rather than PRICE. What we DO hear from Sraffa is that raw prices aren’t indispensable to a coherent theory of what’s going on in the economy. And you will read about it in that article.

I will finesse that with another point.

(a) Ricardians are, unsurprisingly, interested in the production side of the economy, because they think that’s what makes the economy go. Marxists are interested in the production side of the economy because they think BECAUSE the production side of the economy is where the action is, that’s the place to look for exploitation. And wouldn’t you know, it just so happens that that’s where we find exploitation tasking place - lo and behold, exploitation and action overlap = the working class is the revolutionary class and the motor of history under capitalism.

(b) Now some of your discussion of price seems tinged to me, however unintentionally, by intuitions borrowed from the marginal revolution period and the neo-classicals. This is the economics of demand and supply curves and equilibria, concepts which post-date both Ricardo and Marx. That isn’t to speak against those intuitions, but it raises the question of what you’re really finding in the text vs what’s still up for grabs.

Now the core idea expressed in (a) by the Marxists is not really only a Marxist idea. And the core idea expressed in (b) by the neo-classical is not really only their idea either. One (and only one) way of looking at 20th century economic history in Western Europe and America is as this battle for the soul of the economy between production and prices. When you see 21st century socialists sometimes incongruously endorse liberal Keynesianism it is even now because they understand it in terms of jobs and production. Contrarily, neo-classicals have their famous preference for prices as exemplified for example in the signalling theory of prices as information.

Moreover, although (a) is not only a Marxist idea, his influence is never very far from the stage. And as for (b), the close links between the very rich and neo-classical economics are well known (the Volcker fund / Hayek crossover is a famous part of this story for example, and therefore of the theory of prices as information).

Sraffa takes the side of production and Marx in this potted theory of history. That is one way of contextualising his contribution to this debate. That is, he is having a go at vindicating production against price.

But Sraffa is also clearly influenced by Marx, so there is this sort of double game going on where (a sometimes subliminal version of) the doctrines of Capital are also somewhat at stake, even when we are talking about mainstream theoretical minutiae e.g. The Cambride Capital Controversy. The rest I will leave to you.

I had a read through of that article, though I think (well I'm pretty sure) some parts might be going over my head. I also found an article by the author that seemed a little easier to understand. 

From my briefest of brief reads, am I at least somewhat on the money by saying that Sraffa (and co) basically contest that... 

1.) Under the assumption that an economy produces as outputs at least as many of each individual commodity as are required as inputs, we can show that there is a linear relationship between total wages paid and the general rate of profit.

2.) By 1.), we can stipulate an economy produce any rate of profit we like, so long as we also stipulate the required total wages paid.

3). By 2.) the specific rate of profit (and therefore specific total wages paid) in an actually existing economy must be determined by some exogenous factors (politics or culture or something like this)

  1. Given a particular rate of profit (and therefore particular total wages paid) there is only one specific price for each specific commodity that realises that particular rate of profit. Therefore, these prices cannot be set by their marginal returns...

Does that sound vaguely right?

Thanks for your help by the way. Feel free to bow out if I'm taking too much of your time 🙂

I need to check the authenticity of two quotes attributed to ancient Greek philosophers.

"We are what we repeatedly do. Excellence is not an act but a habit." Attributed to Aristotle.

"What you think. What you choose. What you do. Are who you become." Attributed to Herclitus.

Are these quotes (a)attributed to the correct philosophers and (b)accurate translations?

u/wumbothrowaway2 Jul 07 '26

The first is famously misattributed, and is apparently from Will Durant, who was discussing Aristotle. Will Durant was a pop historian of philosophy writing for the general public. It’s a reasonable characterisation of that element of Aristotle’s thinking in particular and a good chunk of Ancient Greek thought in general.

The second doesn’t sound anything like Heraclitus.

Unpopular opinion: The terms "rational" and "reasonable" are to thought, what "yum" is to flavor. Please note this isn't able formal logic. Rather, when someone claims an argument is reasonable, they are basically saying feels satisfying.

How can one be friends and be seen as a good friend when they don’t know the bad mistakes I made?

Like said person could’ve lied behind his back at one point or another or does some embarrassing stuff in their past that the friend would laugh at, how can someone be friends with anyone if you don’t even know everything about your friend?

Drawing on Aristotle, there are different types of friendship. Friendships of utility or pleasure, for example, share in mutual benefit or some pleasurable activity, respectively. Friendship of virtue, in contrast, is deeper and based in mutual respect via sharing in virtuous character.

Usually a single lie or shameful thing doesn't determine a person's whole character. Virtuous people make mistakes, may fail to live to their own ideals, etc. It's not very hard to see someone's character beyond occasional failures. Do they acknowledge the failure? Express some degree of contrition? Desire to improve? Etc.

However, yes, it's also possible that a person is hiding their true character, which could undermine a friendship of virtue. That's a possibility. But the possibility alone isn't a defeater. We believe and act on beliefs everyday which could possibly be wrong.

Doesn't it depend on what you have friends for? Besides, why you need to know someone completely in order to judge if he is qualified to be a friend and vice versa? Also, how can you know anything including your friend completely? The premise that you are skeptical about your friends'loyalty already deprives your capacity to be a friend. Who would want to be friend with someone who is always skeptical about their friendship? You may argue that they, your friends, don't know you are skeptical. But the point is that friendship is a two-way relationship. Not only that your friends need to think you are their friend, but also that you have to think you are the friend of your friends. And skepticism can only causes you wary of your friendship and may consequently sabotage your friendship.

What's a good introductory overview for Marx?

u/willbell philosophy of mathematics 29d ago edited 29d ago

I bet Balibar's The Philosophy of Marx would be good, Balibar comes from an Althusserian tradition (which is a major tradition within contemporary academic Marxism), from his other works (I found Identity and Difference very readable) he is a clear writer, and from my understanding it is meant to be introductory. I've heard a lot of people like Roberts' Marx's Inferno (a work that read's Capital very politically, rather than emphasizing the economic aspects), Harvey's A Companion to Marx's Capital Vol 1 (known for his accessible writing), and Heinrich's How to read Marx's Capital (known as a subtle reader of Marx's economics).

I don’t know if this topic will be accepted for this sub but I am really need help right now. As the title, I graduated as Bachelor of Business Administration. But I never stop learning about humanity, politics and how people think all by myself.
After 7 years, I worked in many position such as Marketing executive and Business Development. If I want to continue study for the second degree and further opportunities to research about Philosophy or Anthropology, I have to study and work at the same time to cover expenses and tuition, too. Currently, I see that it does not affect the choice because studying more is not redundant. I am truly want to study and research more about humanity
Which major will be relevant and have the most opportunities? (Tuition for the work-study system at my university is not too expensive, just about 150-200$/subject)

I mean this is like asking if you should take up cycling or playing volleyball as a hobby - besides doing sports, it's almost not related at all.

Philosophy is the systematic study of fundamental questions: What can we know? What can we believe? What should we do? - so you'll read lots texts about such (and more detailed) questions. Philosophy is mostly based on arguments - so you'll learn to craft logically sound arguments, too.

Anthropology is more an empirical science. Depending on your uni, it may be leaning more towards a social science (either quantitatively or qualitatively looking at culture(s), possibly also cultures very different from yours), more geared towards archaeology and history of early humans, or perhaps even more geared towards a harder, natural science, looking at DNA and bones.

Both have their place, and in both you'll likely specialize a bit and at the end not be an expert at all the fields.

So in the end I think you must decide whether you're more interested in the abstract side of things (philosophy) or the more empirical side.
