The heart of a fool is in the mouth, but the mouth of a wise man is in his heart.

There is as much greatness of mind in acknowledging a good turn, as in doing it.

Men who reject the responsibility of thought and reason can only exist as parasites on the thinking of others.

If everyone is thinking alike, then somebody isn't thinking.

Hold thought steadfastly to the enduring, the good, and the true, and you will bring these into your experience proportionately to their occupancy of your thoughts.

It isn't what you have, or who you are, or where you are, or what you are doing that makes you happy or unhappy. It is what you think about.

If you spend too much time thinking about a thing, you'll never get it done.

And if all others accepted the lie which the Party imposed—if all records told the same tale—then the lie passed into history and became truth.

The oldest, shortest words - “yes” and “no” - are those which require the most thought.

Almost every significant breakthrough is the result of a courageous break with traditional ways of thinking.

Those who are free of resentful thoughts surely find peace.

Ignorance never settle a question.

We should be careful to get out of an experience only the wisdom that is in it—and stop there; lest we be like the cat that sits down on a hot stove lid. She will never sit down on a hot stove lid again—and that is well; but also she will never sit down on a cold one any more.

The opinion of 10,000 men is of no value if none of them know anything about the subject.

The man who is truly good and wise will bear with dignity whatever fortune sends, and will always make the best of his circumstances.

Grant me, O Lord my God, a mind to know you, a heart to seek you, wisdom to find you, conduct pleasing to you, faithful perseverance in waiting for you, and a hope of finally embracing you. Amen.

You are a fool in four letters, my son.

Great wisdom is generous, petty wisdom is contentious. Great speech is impassioned, small speech in cantankerous.

The wise man accepts his pain, endures it, but does not add to it.

Wisdom is nothing but a preparation of the soul, a capacity, a secret art of thinking, feeling and breathing thoughts of unity at every moment of life.
