The only way to enjoy the fun of catching people behaving disgustingly is to have children. One has to keep having them, however, because it is incorrect to correct grown people, even if you have grown them yourself.

The conduct of our lives is the true mirror of our doctrine.

Right conduct can never, except by some rare accident, be prompted by ignorance or hindered by knowledge.

Fine conduct is always spontaneous.

Yasha spent his Sabbath talking and smoking cigarettes among musicians. To the earnest moralists who attempted to get him to change his ways, he would always answer: "When were you in heaven, and what did God look like?"

It is in our collective behavior that we are most mysterious.

You wouldn't be caught wearing cheap perfume, would you? Then why do you want to wear cheap perfume in your conduct?

With a gentleman I am always a gentleman and a half, and with a fraud I try to be a fraud and a half.

You've got to have something to eat and a little love in your life before you can hold still for any damn body's sermon on how to behave.

Best behavior means the same thing as the most uncomfortable behavior.
