- Edward de Bono

I claim that human mind or human society is not divided into watertight compartments called social, political and religious. All act and react upon one another.

The secret of health for both mind and body is not to mourn for the past, not to worry about the future, not to anticipate the future, but to live the present moment wisely and earnestly.

- Buddha

Beauty in things exists in the mind which contemplates them.

- David Hume

The mind thinks thoughts that we don't plan. It's not as if we say, "At 9:10 I'm going to be filled with self-hatred."

- Sharon Salzberg

All wrong-doing arises because of mind. If mind is transformed can wrong-doing remain?

When we talk about understanding, surely it takes place only when the mind listens completely -- the mind being your heart, your nerves, your ears -- when you give your whole attention to it.

- Jiddu Krishnamurti

Freethinkers are those who are willing to use their minds without prejudice and without fearing to understand things that clash with their own customs, privileges, or beliefs.

- Leo Tolstoy

I would rather live in a world where my life is surrounded by mystery than live in a world so small that my mind could comprehend it.

- Harry Emerson Fosdick

If the human brain were so simple that we could understand it, we would be so simple that we couldn't.

- Emerson M. Pugh

I am part of the sun as my eye is part of me. That I am part of the earth my feet know perfectly, and my blood is part of the sea. There is not any part of me that is alone and absolute except my mind, and we shall find that the mind has no existence by itself, it is only the glitter of the sun on the surfaces of the water.

- D. H. Lawrence

If you realized how powerful your thoughts are, you would never think a negative thought.

Education's purpose is to replace an empty mind with an open one.

- Malcolm Forbes

Our progress as a nation can be no swifter than our progress in education. The human mind is our fundamental resource.

- John F. Kennedy

We must learn that competence is better than extravagance, that worth is better than wealth, that the golden calf we have worshiped has no more brains than that one of old which the Hebrews worshiped. So beware of money and of money's worth as the supreme passion of the mind. Beware of the craving for enormous acquisition.

- C. A. Bartol

Few is the number who think with their own minds and feel with their own hearts.

- Albert Einstein

It is exercise alone that supports the spirits, and keeps the mind in vigor.

- Cicero

Whether we grow more gross, more selfish, more grasping, more vulgar, more dishonorable, or whether we grow more delicate, more tender, more sympathetic, more aspiring, or more affectionate does not depend on whether we think the mind quantitative or qualitative. It depends on what we think of the values of those qualities. And I for one choose so-called spiritual qualities of mind and character because for me they contain the most enduring and highest joys of earth. Therefore, in this practical sense I am a firm believer in the spiritual life. And when I use the term as I frequently do, it is in this sense that I use it.

- John Dietrich

The heart is the first feature of working minds.

The heart is the first feature of working minds.

Facts are to the mind what food is to the body.

- Edmund Burke

The heart has eyes which the brain knows nothing of.

- Charles H. Perkhurst

Everything is based on mind, is led by mind, is fashioned by mind. If you speak and act with a polluted mind, suffering will follow you, as the wheels of the oxcart follow the footsteps of the ox. Everything is based on mind, is led by mind, is fashioned by mind. If you speak and act with a pure mind, happiness will follow you, as a shadow clings to a form.

- Buddha

It matters more what's in a woman's face than what's on it.

- Claudette Colbert

Sendentary people are apt to have sluggish minds. A sluggish mind is apt to be reflected in flabbiness of body and in a dullness of expression that invites no interest and gets none.

- Rose Fitzgerald Kennedy

It is only through your conscious mind that you can reach the subconscious. Your conscious mind is the porter at the door, the watchman at the gate. It is to the conscious mind that the subconscious looks for all its impressions.

- Robert Collier

See, the human mind is kind of like ... a pinata. When it breaks open, there's a lot of surprises inside. Once you get the pinata perspective, you see that losing your mind can be a peak experience.
[The Search for Signs of Intelligent Life in the Universe]

- Jane Wagner

The mind that is wise mourns less for what age takes away; than what it leaves behind.

- William Wordsworth

The greatest minds are capable of the greatest vices as well as of the greatest virtues.

- Rene Descartes

Mathematics as an expression of the human mind reflects the active will, the contemplative reason, and the desire for aesthetic perfection. Its basic elements are logic and intuition, analysis and construction, generality and individuality.

- Richard Courant

New insights fail to get put into practice because they conflict with deeply held internal images of how the world works ... images that limit us to familiar ways of thinking and acting. That is why the discipline of managing mental models -- surfacing, testing, and improving our internal pictures of how the world works -- promises to be a major breakthrough for learning organizations.

- Peter Senge

Instinct is the nose of the mind.

- Madame De Girardin

I don't believe in intuition. When you get sudden flashes of perception, it is just the brain working faster than usual. But you've been getting ready to know it for a long time, and when it comes, you feel you've known it always.

- Katherine Anne Porter

Intuition and concepts constitute ... the elements of all our knowledge, so that neither concepts without an intuition in some way corresponding to them, nor intuition without concepts, can yield knowledge.

The intuitive mind is a sacred gift and the rational mind is a faithful servant. We have created a society that honors the servant and has forgotten the gift.

- Albert Einstein

Peace is not achieved by controlling nations, but mastering our thoughts.

The fundamental fact about the Greek was that he had to use his mind. The ancient priests had said, "Thus far and no farther. We set the limits of thought." The Greek said, "All things are to be examined and called into question. There are no limits set on thought."

- Edith Hamilton

Unthinking faith is a curious offering to be made to the creator of the human mind.

- John A. Hutchinson

Logicians have but ill defined
As rational the human mind.
Logic, they say, belongs to man,
But let them prove it if they can.

- Oliver Goldsmith
