"Why shouldn’t I eat toothpaste? It’s a free world. Why shouldn’t I chew my toenails? i happen to have trodden in some honey. Why shouldn’t I prance across central park with delicate sideways leaps? I know what your answer will be: “it isn’t done”. But it’s no earthly use just saying it isn’t done. If there’s a reason why it isn’t done, give the reason—if there’s no reason, don’t attempt to stop me doing it. All other things being equal, the mere fact that something “isn’t done” is in itself an excellent reason for doing it."

“When I consider the parts of the past of which I have some knowledge, I am inclined to believe that, in Utilitarian hedonistic terms, the past has been worth it, since the sum of happiness has been greater than the sum of suffering.”

“What now matters most is that we rich people give up some of our luxuries, ceasing to overheat the Earth's atmosphere, and taking care of this planet in other ways, so that it continues to support intelligent life.”

“If we believe that there are some irreducibly normative truths, we might be believing what we ought to believe. If there are such truths, one of these truths would be that we ought to believe that there are such truths. If instead we believe that there are no such truths, we could not be believing what we ought to believe. If there were no such truths, there would be nothing that we ought to believe.”

“I sometimes want to kick my car Since I have this anger at material objects, which is manifestly irrational, it’s easier to me to think, when I get angry with people, that this is also irrational.”

“Until this century, most of mankind lived in small communities. What each did could affect only a few others. But conditions have now changed. Each of us can now, in countless ways, affect countless other people. We can have real though small effects on thousands or millions of people. When these effects are widely dispersed, they may be either trivial, or imperceptible. It now makes a great difference whether we continue to believe that we cannot have greatly harmed r benefited others unless there are people with obvious grounds for resentment or gratitude.”

“Nagel once claimed that it is psychologically impossible to believe the Reductionist View. Buddha claimed that, though it is very hard, it is possible. I find Buddha’s claim to be true. After reviewing my arguments, I find that, at the reflective or intellectual level, though it is very hard to believe the Reductionist View, this is possible. My remaining doubts or fears seem to me irrational. Since I can believe this view, I assume that others can do so too. We can believe the truth about ourselves.”
