On the one hand, our social nature is our greatest beauty - it means that we have natural empathy and sympathy. But our social nature also means that we may let ourselves be controlled by the judgments of others, precisely because we care so much about our status in community.

I like to think of power back in its Latin root, its meaning comes from posse - to be able.

I think that luxury has nothing to do with money, and everything to do with beauty.

We are very much social creatures who model ourselves on one another.

Little wonder that it can seem unthinkable to say "no, thanks" to the modern-day equivalent of our tribe - our fear-driven culture.

[Fear] means that we are human beings walking into the unknown, and that we are risking breaking with others for something we believe in.

The problem is that our whole tribe - if you will, the larger community of humanity itself - is on a death march ecologically and in terms of the intensification of violence and conflict.
