Different moralities must share some general features if they are to perform their functions of coordinating beings having particular kinds of motivations. Morality is a cultural construction in something like the way bridges are. There would be no bridges unless human beings used them to move across bodies of waters or depressions in the earth, but a good bridge cannot be designed according to whim, but rather according to what would adequately fulfill their function and the nature of the materials that are available for their construction.

That ability to see the right choice, but not until several hours have passed since making the wrong one? That's what makes a person a dumbass, folks.

We can cooperate more easily with those who more easily intelligible to us, who are more familiar to us. But the advantages of specialization of labor often push us in the direction working with people who have different strengths and viewpoints than we do. I think that this is one major reason why moralities are always subject to change, because some of the people we cooperate with are going to be different from us in ways that often lead them to have different value orientations than we have; and interacting with them can change us.

The English language needs a word for that feeling you get when you badly need help, but there is no one you can call because you're not popular enough to have friends, not rich enough to have employees, and not powerful enough to have lackeys. It is a very distinct cocktail of impotence, loneliness and a sudden stark assessment of your non-worth to society? Enturdment?

... life is a flickering candle we all carry around. A gust of wind, a meaningless accident, a microsecond of carelessness, and it's out. Forever.

All of society is built to prop up that lie, the whole world a big, noisy puppet show meant to distract us from the fact that at the end, you'll die, and you'll probably be alone.

People come to have different moral beliefs because they have different non-moral beliefs about relevant facts. People are disposed to believe whatever justifies the practices and institutions that benefit them. But I argue that not all moral differences can be explained away in such a fashion. Some of the most profound disagreements come from differences in priority assigned to values such as relationship and community on the one hand, and individual rights and personal autonomy for the individual, on the other hand.
