people are like fish

A school of fish. They swim together like a flock of birds.

It's not just religions, or ethnicities, or tribes, it's ideologies. It's social cliques, sexualities, corporations. People like to be in a group, they like to blend in, and represent that group, and defend it, and identify with and as it.

This seems to be political, but it's not. It's just a mentality. As the old saying goes, either you are in, or you are out.

Perhaps that's what philosophy appeals to, or who it appeals to. The un-tribed, the outcast. The random free thinker.

But even as we do this, we are grouping ourselves informally—we like philosophy.
