>What do you mean by "fundamentally social"?

You first used it in the context of us being fundamentally social not selfish.

So I took it to be a definition which excludes the real reason being selfish. So I oppose the idea that they are mutually exclusive.

>Do you want to say we aren't fundamentally cooperative/altruistic/empathetic towards others? (somewhere along these lines)

It feels like we are getting at psychological egoism.

>Psychological egoism is the view that humans are always motivated by self-interest and selfishness, even in what seem to be acts of altruism. It claims that, when people choose to help others, they do so ultimately because of the personal benefits that they themselves expect to obtain, directly or indirectly, from so doing.
