When any person treats you ill or speaks ill of you, remember that he does this or says this because he thinks it is his duty. It is not possible, then, for him to follow that which seems right to you, but that which seems right to himself.

The cause of all human evils is the not being able to apply general principles to special cases.

Men are not afraid of things, but of how they view them.

I must die. I must be imprisoned. I must suffer exile. But must I die groaning? Must I whine as well? Can anyone hinder me from going into exile with a smile? The master threatens to chain me: what say you? Chain me? My leg you will chain--yes, but not my will--no, not even Zeus can conquer that.

If any be unhappy, let him remember that he is unhappy by reason of himself alone. For God hath made all men to enjoy felicity and constancy of good.

The pleasure which we most rarely experience gives us greatest delight.

All human beings seek the happy life, but many confuse the means - for example, wealth and status - with that life itself. This misguided focus on the means to a good life makes people get further from the happy life. The really worthwhile things are the virtuous activities that make up the happy life, not the external means that may seem to produce it.
