The future of the world depends on how well we meet it.

There is a growing movement called effective altruism. It's important because it combines both the heart and the head.

Racists violate the principle of equality by giving greater weight to the interests of members of their own race when there is a clash between their interests and the interests of those of another race. Sexists violate the principle of equality by favoring the interests of their own sex. Similarly, speciesists allow the interests of their own species to override the greater interests of members of other species. The pattern is identical in each case.

Cheats prosper until there are enough who bear grudges against them to make sure they do not prosper.

I'd much rather be part of a society which greatly honors and respects people who are altruists and who are effective in their altruism, than one that either admires people because they're, you know, celebrity movie stars or because they're super wealthy just no matter what they do with their wealth because I think we ought to try to encourage more people to act in that way.

We have a new generation of very rich people who want to do more with their money than buy a lot of expensive toys. They want to live meaningful lives.

To give preference to the life of a being simply because that being is a member of our species would put us in the same position as racists who give preference to those who are members of their race.
