“There is truth in wine and children” 

I told my wife the truth. I told her I was seeing a psychiatrist. Then she told me the truth: that she was seeing a psychiatrist, two plumbers, and a bartender.

“In truth the prison unto which we doom ourselves no prison is” 

“One of the common failings among honorable people is a failure to appreciate how thoroughly dishonorable some other people can be, and how dangerous it is to trust them.” 

“There are only two ways of telling the complete truth--anonymously and posthumously.” 

“People who pride themselves on their "complexity" and deride others for being "simplistic" should realize that the truth is often not very complicated. What gets complex is evading the truth.” 

“If you tell the truth, you don't have to remember anything.”

 “To thine own self be true.”

Many a true word hath been spoken in jest.

Show me one person who cares how they act, someone for whom success is less important than the manner in which it is achieved. While out walking, who gives any thought to the act of walking itself? Who pays attention to the process of planning, not just the outcome?

The man who spends his time choosing one resort after another in a hunt for peace and quiet, will in every place he visits find something to prevent him from relaxing.

Whatever the nature of the whole does, and whatever serves to maintain it, is good for every part of nature.

Whether the universe is a concourse of atoms, or nature is a system, let this first be established: that I am a part of the whole that is governed by nature; next, that I stand in some intimate connection with other kindred parts.

Either all things proceed from one intelligent source and come together as in one body, and the part ought not to find fault with what is done for the benefit of the whole; or there are only atoms, and nothing else than mixture and dispersion. Why, then, are you disturbed?

For what does reason purport to do? “Establish what is true, eliminate what is false and suspend judgement in doubtful cases”.

Resolve to accept whatever happens as necessary and familiar, flowing like water from that same source and spring.

Because what is a human being? Part of a community – the community of gods and men, primarily, and secondarily that of the city we happen to inhabit, which is only a microcosm of the universe in toto.

Why are we still lazy, indifferent and dull? Why do we look for excuses to avoid training and exercising our powers of reason?

Perfect tranquility within consists in the good ordering of the mind, the realm of your own.

When you wake up in the morning, tell yourself: The people I deal with today will be meddling, ungrateful, arrogant, dishonest, jealousand surely… None of them can hurt me. Don’t waste the rest of your time here worrying about other people… It will keep you from doing anything useful. Why do you not rather act than complain?

Constantly and, if it be possible, on the occasion of every impression on the soul, apply to it the principles of physics, ethics, and dialectics (logic).

Whenever anyone criticizes or wrongs you, remember that they are only doing or saying what they think is right. They cannot be guided by your views, only their own; so if their views are wrong, they are the ones who suffer insofar as they are misguided.

Say to yourself each time, ‘He did what he believed was right.’ (When someone does something you don’t like)

How small a part of the boundless and unfathomable time is assigned to every man! For it is very soon swallowed up in the eternal. And how small a part of the whole substance! And how small a part of the universal soul! And on what a small clod of the whole earth you creep!
