The erosion of agency has consequences for our politics. As a result of all this, the fundamental ethical challenge of the anthropocene is the recovery of agency, or alternatively to come to terms with its loss and to understand how to go on.

The most fundamental challenge of the anthropocene concerns agency. For those who lived the Enlightenment dream (always a minority but an influential one), agency was taken for granted. There were existential threats to agency (e.g., determinism) but philosophy mobilized to refute these threats (e.g., by defending libertarianism) or to defuse them (e.g., by showing that they were compatible with agency).

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.

Aristotle thought that humans are rational animals and Hobbes thought that we act on the basis of rational self-interest. If only! It's not that we never do these things, it's that they are hardly constituative of who and what we are.

One of the real dangers of our time is people's indifference to history.

I'm a subjectivist about morality.

Much of the point of individual action is really to communicate with other people and with political leaders and to demonstrate to them that we are willing to live lives which are less dependent on fossil fuels and we'll show you that now by changing our individual life to some extent but we want you to take action, political leaders, so that we aren't living in a society in which we're dependent on poisoning the future in order to maintain present lifestyles.
