The whole contains nothing that is not for its advantage. By remembering that I am part of such a whole, I shall be content with everything that happens.

He that lives alone lives in danger; society avoids many dangers.

From Apollonius I learned freedom of will and undeviating steadiness of purpose; and to look to nothing else, not even for a moment, except to reason.

Remember that man lives only in the present, in this fleeting instant; all the rest of his life is either past and gone, or not yet revealed.

Our life is what our thoughts make it.

If you are pained by any external thing, it is not this that disturbs you, but your own judgment about it.

Enough of this wretched life and murmuring and apish tricks. Why art thou disturbed? What is there new in this? What unsettles thee? Is it the form of the thing? Look at it. Or is it the matter? Look at it. But besides these there is nothing. Towards the gods, then, now become at last more simple and better. It is the same whether we examine these things for a hundred years or three.
