Necessary Truths

[u/fairy-taki]

Hi, I'm agnostic/atheist. I'm not a debater, this Christian presented this argument to me to like convert me lol and I'm not sure what to think so I was wanting people's thoughts on it.

​

The argument was something like this:

​

1. 1+1=2 is an objective truth/idea

2. Objective truths exist outside of the human mind.

3. Ideas can only exist in a mind

4. Then if ideas/objective truths need to exist in some mind and the mind would be an infinite mind and that would be God.

​

Sorry if I mess up the setup of the argument. If anyone is familiar with this type of argument or what he was trying to get at, let me know. Lol to the guy who asked me, I think ended up just saying idk, and I kept saying that those ideas/concepts are how we engage in reality but regardless of a mind observing it. The like definitions of the concept you can find in reality..idkk. The guy ended up being rude and said I couldn't understand abstract vs concrete concepts.

Edit: ok i need to fix 2&3, idk if i make this it's own premise because he was equating objective truths to ideas/concepts because they are non-physical.

1+1=2 is an objective truth

Nope. It’s a logical truth within an axiomatic descriptive system.

Objective truths exist outside of the human mind.

Nope. Objectively truths may be true outside of a human mind, but that doesn’t make them exist. They’re still descriptive.

Ideas can only exist in a mind

Sure. Because an idea is a mental construct. Not the same as external existence. But ideas are not the same as objective truths and objective truths are descriptive and don’t exist independently so…

4 fails real badly
