/lit/ - Literature

What do you think is the nature of man? If you wanted to check whether someone was a human or just some other kind of intelligent alien, how would you do it? What question would you ask them? What would be the "most human" answer?

Please help, I need this for a book.

Help me out /lit/, I need to find the name of something

There is this method of critical thinking where you keep asking "Why do you think X is the case" and when the answer is Y then you ask again "Why do you think Y is the case" and repeat this until you end up at the most basic assumption that is the basis of the logical construct that lead you to that original belief.

That method had a name and I am pretty sure its from an ancient greek or roman philosopher, but I can't remember.
