In the face of the collective action problems that are at the heart of the environmental crisis, consequentialists should seek to inculcate the "green virtues" which includes the virtue of cooperativeness. This would not bring about the best possible world but it would set us on the path of making it better.

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).

Our differences should not be exaggerated.

Ethical systems are fundamentally conservative and primarily directed towards regulating interactions within communities.

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.

People with long memories and a vivid sense of the past have an immediate understanding of politicians like Donald Trump. They are not surprised by the behavior of Google, a corporation that notionally (until recently anyway) espoused the slogan "don't be evil" and then runs over individual people and even entire nations in the pursuit of profit.

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.
