Observe constantly that all things take place by change, and accustom thyself to consider that the nature of the Universe loves nothing so much as to change the things which are, and to make new things like them.

Whoever values peace of mind and the health of the soul will live the best of all possible lives.

Remember that all is opinion. For what was said by the Cynic Monimus is manifest: and manifest too is the use of what was said, if a man receives what may be got out of it as far as it is true.

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.

Do not be wise in words - be wise in deeds.

Nature which governs the whole will soon change all things which you see, and out of their substance will make other things and again other things... in order that the world may be ever new.

Stop talking about what the good man is like, and just be one.
