Culture isn't biological, though I get what he means, culture is an inherent byproduct of intelligent life. But culture itself is an axiom built on a singular intelligence. This singular, relative intelligence comes first. You don't experience through the minds of society, but only your own mind. Think about the idiocy in your own mind putting the minds of others before itself. It makes no logical sense. If you want to argue of a "greater good", which for the most part is fluff, it's basically arguing from a hivemind point of view. A mind coming from all collectively Let's take a look at this mind: it's composed of a number of very different minds. To any sane person this mind would appear batshit crazy Now imagine of one mind took over all of the others in this hivemind. That's sanity

No matter which point you argue from, logic is nothing but a higher form of selfishness
