This publication of Harvard Classics contains quotations and writing of famous authors.

[Plato, writing a speech of Socrates]
 
p.11 And so I go my way, obedient to the god, and make inquisition into the wisdom of anyone, whether citizen or stranger, who appears to be wise; and if he is not wise, then in vindication of the oracle I show him that he is not wise; and this occupation quite absorbs me, and I have no time to give either to any public interest or to any concern of my own
 
p.11 there are plenty of persons... who think that they know something, but really know little or nothing
 
p.76-77 Socrates... asked them what they thought of the argument, and whether there was anything wanting? For, said he, much is still open to suspicion and attack, if anyone were disposed to sift the matter thoroughly... if you are still doubtful about the argument do not hesitate to say exactly what you think, and let us have anything better which you can suggest; and if I am likely to be of any use, allow me to help you. Simmias said: I must confess, Socrates, that doubts did arise in our minds
 
[sayings of Epictetus]
 
p.132 The beginning of philosophy is to know the condition of one's own mind.
 
p.140 When a youth was giving himself airs in the Theatre and saying, "I am wise, for I have conversed with many wise men," Epictetus replied, "I too have conversed with many rich men, yet I am not rich!"
 
p.143 If a man would pursue Philosophy, his first task is to throw away conceit. For it is impossible for a man to begin to learn what he has a conceit that he already knows.
 
p.144 "The question at stake," said Epictetus, "is no common one; it is this: - Are we in our senses, or are we not?"
 
p.153-154 If a man has frequent [interaction] with others, either in the way of conversation, entertainment, or simple familiarity, he must either become like them, or change them to his own fashion. A live coal placed next to a dead one will either kindle that or be quenched by it. Such being the risk, it is well to be cautious in admitting intimacies of this sort, remembering that one cannot rub shoulders with a soot-stained man without sharing the soot oneself.
 
[The Meditations of Marcus Aurelius]
 
p.218 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. For everything that exists is in a manner the seed of that which will be.
 
p.228 To seek what is impossible is madness
 
p.229 Often think of the rapidity with which things pass by and disappear, both the things which are and the things which are produced. For substance is like a river in a continual flow, and the activities of things are in constant change, and the causes work in infinite varieties; and there is hardly anything which stands still. And consider this which is near to thee, this boundless abyss of the past and of the future in which all things disappear.
 
[Additional sayings of Epictetus]
If you wish to be a writer, write.
 
All philosophy lies in two words, sustain and abstain.
 
Be careful to leave your sons well instructed rather than rich, for the hopes of the instructed are better than the wealth of the ignorant.
 
No great thing is created suddenly.
 
Not every difficult and dangerous thing is suitable for training, but only that which is conducive to success in achieving the object of our effort.
 
The world turns aside to let any man pass who knows where he is going.
 
[Additional quotes from Socrates]
Employ your time in improving yourself by other men's writings, so that you shall gain easily what others have labored hard for.
 
True wisdom comes to each of us when we realize how little we understand about life, ourselves, and the world around us.
 
An honest man is always a child.
 
Beware the barrenness of a busy life.
 
Regard your good name as the richest jewel you can possibly be possessed of - for credit is like fire; when once you have kindled it you may easily preserve it, but if you once extinguish it, you will find it an arduous task to rekindle it again. The way to gain a good reputation is to endeavor to be what you desire to appear.

Philosophy begins with wonder

Do not be angry with me if I tell you the truth

To find yourself, think for yourself

The only true wisdom is in knowing you know nothing.

Remember that there is nothing stable in human affairs; therefore avoid undue elation in prosperity, or undue depression in adversity.

Let him that would move the world first move himself. 

[Additional quotes from Marcus Aurelius]
Because a thing seems difficult for you, do not think it impossible for anyone to accomplish.
 
Begin - to begin is half the work, let half still remain; again begin this, and thou wilt have finished.
 
Everything we hear is an opinion, not a fact. Everything we see is a perspective, not the truth.
 
Forward, as occasion offers. Never look round to see whether any shall note it... Be satisfied with success in even the smallest matter, and think that even such a result is no trifle.
 
How much time he saves who does not look to see what his neighbor says or does or thinks.
 
Perhaps there are none more lazy, or more truly ignorant, than your everlasting readers.
 
The object of life is not to be on the side of the majority, but to escape finding oneself in the ranks of the insane.
 
The secret of all victory lies in the organization of the non-obvious.
 
We are too much accustomed to attribute to a single cause that which is the product of several, and the majority of our controversies come from that.
 
[Additional quotes from Plato]
A good decision is based on knowledge and not on numbers.
 
Apply yourself both now and in the next life. Without effort, you cannot be prosperous.
 
You can discover more about a person in an hour of play than in a year of conversation.
 
Whatever deceives men seems to produce a magical enchantment.
 
The direction in which education starts a man will determine his future in life.
