The mark of a mature, psychologically healthy mind is indeed the ability to live with uncertainty and ambiguity, but only as much as there really is. Uncertainty is no virtue when the facts are clear, and ambiguity is mere obfuscation when more precise terms are applicable.

Happiness is not the same as life satisfaction, while neither are identical to what we might call flourishing.

People should not expect the state to protect them from fraudsters. If we do, we get into the habit of neglecting our own powers of intellectual discernment.

I think that a lot of social movements, political movements, powerful ones - certainly they form, collectively, an idea of the truth which becomes hard to question. It becomes a dogma, and from the inside it starts to look like common sense.

You should protest about the views of people you disagree with over major moral issues, and argue them down, but you should not try to silence them, however repugnant you find them. That is the bitter pill free speech requires us to swallow.

Seek first what is true and of value, and then whatever happiness follows will be of the appropriate quantity and, more importantly, quality.

Instead of showing strangers kindness and giving them the benefit of the doubt, we increasingly show them only fear, and that is bad for us and them.
