Philosophy is not a body of knowledge to impart to someone, that's why reading philosophy books isn't always the best way of learning philosophy. Philosophy is really more the process of rational engagement, rational reflection with a diversity of views and ideas and opinions and trying to sort of reason your way through to a more reflective position. I think if you look at it that way, philosophizing is to some extent some small way a part of almost everyone's lives although they don't recognize it as such and a lot of people are embarrassed about it.

Since we're not very good at something as basic as controlling our reproduction, life is really bad for more people than ever before.

The density of human population combined with the development of powerful and largely unconstrained technology has given us the problems of the anthropocene and the serious possibility of self-caused extinction.

We need to use economic instruments such as carbon taxes, cap and trade, tax and dividend and whatever else to help incentivize behavior that will move us to a post-carbon, post-animal agriculture world, and make our societies more resilient to the shocks that are already baked into the system. But that doesn't make climate change an "economic issue."

If we don't have historical consciousness we can't really understand problems in all their dimensions, and if we can't understand problems than we can't find solutions.

The millennium development goals are important, both morally and economically, because much of the world's population maybe is as much as a third of the world's population hasn't yet reached the level of economic development where we begin to get a dissociation from people's economic status and their reports about personal happiness. So we really do need to do much more and much more effectively in order to give everyone the kind of basis for which they can have good vibes.

Climate scientists think of nothing but climate and then express their concerns in terms of constructs such as global mean surface temperature. But we live in a world in which all sorts of change is happening all the time, and the only way to understand what climate change will bring is to tell stories about how it manifests in people's lives.
