Being able and willing to complain is what makes us rational and moral animals, capable of seeing and articulating the difference between how things are and how they should be.

Accepting that the world is full of uncertainty and ambiguity does not and should not stop people from being pretty sure about a lot of things.

The greatest moral failing is to condemn something as a moral failing: no vice is worse than being judgmental.

Many people are never happier than when they get the opportunity to complain, while others are deeply unhappy with how things are but just accept the fact. Complaint occurs when we refuse to accept that things are wrong and we do something about it, even if that something is simply articulating our unease.

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.

To become a stoic is to endorse the truthfulness of its world view and accept its prescription for how you ought to live, not just to like how it makes you feel.
