How ridiculous not to flee from one's own wickedness, which is possible, yet endeavor to flee from another's which is not.

He who lives in harmony with himself lives in harmony with the universe.

From Alexander the Platonic, not frequently nor without necessity to say to any one, or to write in a letter, that I have no leisure; nor continually to excuse the neglect of duties required by our relation to those with whom we live, by alleging urgent occupations.

Since you are an integral part of a social system, let every act of yours contribute to the harmonization of social life. Any action that is not related directly or remotely to this social aim disturbs your life, and destroys your unity.

The soul is dyed by the thoughts. Dye it then, with a continuous series of such thoughts as these - that where a man can live, there - if he will - he can also live well.

How can a man find a sensible way to live? One way and one only- Philosophy. And my philosophy means keeping that vital spark within you free from damage and degradation, using it to transcend pain and pleasure, doing everything with a purpose, avoiding lies and hypocrisy, not relying on another person's actions or failings. To accept everything that comes, and everything that is given, as coming from that same spiritual source.

He who follows reason in all things is both tranquil and active at the same time, and also cheerful and collected.
