Thought

Thought can refer to the ideas or arrangements of ideas that result from thinking, the act of producing thoughts, or the process of producing thoughts. Despite the fact that thought is a fundamental human activity familiar to everyone, there is no generally accepted agreement as to what thought is or how it is created. Thoughts are the result or product of spontaneous acts of thinking.

 * Upon the cunning loom of thought We weave our fancies, so and so.
 * Thomas Bailey Aldrich, "Cloth of Gold", line 3, in The Ballad of Babie Bell and Other Poems (New York: Rudd & Carleton, 1856), p. 19


 * Sempre il miglior non è il parer primiero.
 * First thoughts are not always the best.
 * Vittorio Alfieri, Don Garzia, III, 1; Reported in Hoyt's New Cyclopedia Of Practical Quotations (1922), p. 787-90


 * Thought is something limitless and independent, and has been mixed with no thing but is alone by itself. ... What was mingled with it would have prevented it from having power over anything in the way in which it does. ... For it is the finest of all things and the purest.
 * Anaxagoras, Fragment B12, in Jonathan Barnes, Early Greek Philosophy (1984), p. 190.


 * There are no dangerous thoughts for the simple reason that thinking itself is such a dangerous enterprise.
 * Hannah Arendt, interview with Roger Errera (October 1973), broadcast on Un Certain Regard (6 July 1974), ORTF TV, France. Published as "The Last Interview" in the Hannah Arendt Newsletter #2 (December 1999) and Hannah Arendt: The Last Interview and Other Conversations (Brooklyn: Melvin House, 2013).
 * Widely paraphrased as "There are no dangerous thoughts; thinking itself is dangerous."


 * The kings of modern thought are dumb.
 * Matthew Arnold, Stanzas from the Grande Chartreuse; Reported in Hoyt's New Cyclopedia Of Practical Quotations (1922), p. 787-90


 * "I exist" does not follow from "there is a thought now." The fact that a thought occurs at a given moment does not entail that any other thought has occurred at any other moment, still less that there has occurred a series of thoughts sufficient to constitute a single self. As Hume conclusively showed, no one event intrinsically points to any other. We infer the existence of events which we are not actually observing, with the help of general principle. But these principles must be obtained inductively. By mere deduction from what is immediately given we cannot advance a single step beyond. And, consequently, any attempt to base a deductive system on propositions which describe what is immediately given is bound to be a failure.
 * Alfred Jules Ayer, in Language, Truth, and Logic (1936), p. 47

 * Think about the great thinkers of our time and those times before and in antiquity. Think about Aristotle, Plato and Socrates and Maimonides and Pythagoras, Heraclitus and Rodin and George Washington Carver and Booker T. Washington and Thomas Jefferson and Thomas Edison and Oprah Winfrey and those liberation thinkers like Harriet Tubman and Sojourner Truth and Marcus Garvey and Gandhi and Martin Luther King, Jr., Nelson Mandela. Think about it my brothers and sisters, Cesar Chavez and George Washington Carver and Booker T Washington, Adam Clayton Powell ectera. Think about them! They were [thinkers]. Pitful our generation and our people today. Here it is 2008, and we're worse off now than we've ever been because our young people do not have the ability to — Think about it! How pitiful we are, here they are on drugs, on heroin, on cocaine, alcoholics. Here they are at the disposal of these kingpins and ectera, because they can't. Here they are making gangs families because they can't.
 * Archbishop LeRoy Bailey, Sr., in a sermon entitled "An Abundant Overflowing Thought" (24 Feburary 2008)


 * Great thoughts, like great deeds, need No trumpet.
 * Philip James Bailey, Festus (1813), scene Home


 * Some days my thoughts are just cocoons—all cold, and dull, and blind, They hang from dripping branches in the gray woods of my mind;And other days they drift and shine—such free and flying things! I find the gold-dust in my hair, left by their brushing wings.
 * Karle Wilson Baker, "Days", in B. J. Thompson, ed. Silver Pennies (1925), p. 114


 * The immense majority of individuals, not only among the ignorant masses but also among the civilized and privileged classes, think and want only what everybody else around them thinks and wants. They doubtlessly believe that they think for themselves, but they are only slavishly repeating by rote, with slight modifications, the thoughts and aims of the other conformists which they imperceptibly absorb. This servility, this routine, this perennial absence of the will to revolt and this lack of initiative and independence of thought are the principle causes for the slow, desolate historical development of humanity.
 * Mikhail Bakunin, "Man, Society, and Freedom" (1871)


 * Those who refuse the long drudgery of thought, and think with the heart rather than with the head, are ever the most fiercely dogmatic in their tone.
 * Peter Bayne, Essays in Biography and Criticism: Second Series (Boston: Gould and Lincoln, 1858), Ch. I: "Charles Kingsley", p. 20


 * And thus daily, and month by month, and year by year, he will work at his mind, training it in these consecutive habits of thought, and he will learn to choose that of which he thinks; he will no longer allow thoughts to come and go; he will no longer permit a thought to grip him and hold him; he will no longer let a thought come into the mind and fix itself there and decline to be evicted; he will be master within his own house... he will say: “No; no such anxiety shall remain within my mind; no such thought shall have shelter within my mind; within this mind nothing stays that is not there by my choice and my invitation, and that which comes uninvited shall be turned outside the limits of my mind.
 * Annie Besant, in In the Outer Court (1895)


 * Qui sait si l'on ne verra pas que le phosphore et l'esprit vont ensemble?
 * Who knows whether it is not true that phosphorus and mind are not the same thing?
 * Henri Beyle (Stendhal), Histoire de la Peinture en Italie, Chapter XCI, p. 209. (Ed. 1854); Reported in Hoyt's New Cyclopedia Of Practical Quotations (1922), p. 787-90


 * Sow a thought and reap an act.
 * Quoted by G. D. Boardman, as reported in Hoyt's New Cyclopedia Of Practical Quotations (1922), p. 787-90


 * All that we are is the result of what we have thought: it is founded on our thoughts, it is made up of our thoughts. If a man speaks or acts with an evil thought, pain follows him, as the wheel follows the foot of the ox that draws the carriage… If a man speaks or acts with a pure thought, happiness follows him, like a shadow that never leaves him.
 * Gautama Buddha, The Dhammapada

 * Cujusvis hominis est errare; nullius, nisi insipientis, in errore perseverare. Posteriores enim cogitationes (ut aiunt) sapientiores solent esse.

 * Reader! — You have been bred in a land abounding with men, able in arts, learning, and knowledges manifold, this man in one, this in another, few in many, none in all. But there is one art, of which every man should be'master, the art of reflection. If you are not a thinking man, to what purpose are you a man at all? In like manner, there is one knowledge, which it is every man's interest and duty to acquire, namely, self-knowledge: or to what end was man alone, of all animals, endued by the Creator with the faculty of self-consciousness?
 * Samuel Taylor Coleridge, Aids to Reflection (1854), p. xlvii

 * However closely we may associate thought with the physical machinery of the brain, the connection is dropped as irrelevant as soon as we consider the fundamental property of thought—that it may be correct or incorrect. ...that involves recognising a domain of the other type of law—laws which ought to be kept, but may be broken.

 * Be not troubled by the wanderings of your imagination which you cannot restrain. How often do we wander through the fear of wandering and the regret that we have done so. What would you say of a traveler who, instead of constantly advancing in his journey, should employ his time in anticipating the falls he might suffer, or in weeping over the place where one had happened?

 * Error is popular because people are afraid to grow up. Clear thinking means facing the fact that life is full of difficult problems, that we cannot escape from pain, discomfort and uncertainty, that we cannot obtain happiness by turning away from reality.

 * Frank Herbert, God Emperor of Dune


 * I say that conceit is just as natural a thing to human minds as a centre is to a circle. But little-minded people's thoughts move in such small circles that five minutes' conversation gives you an arc long enough to determine their whole curve. An arc in the movement of a large intellect does not sensibly differ from a straight line. Even if it have the third vowel ['I', the first-person pronoun] as its centre, it does not soon betray it. The highest thought, that is, is the most seemingly impersonal; it does not obviously imply any individual centre.

 * A thought is often original, though you have uttered it a hundred times.

 * Every man who speaks out loud and clear is tinting the "Zeitgeist." Every man who expresses what he honestly thinks is true is changing the Spirit of the Times. Thinkers help other people to think, for they formulate what others are thinking. No person writes or thinks alone—thought is in the air, but its expression is necessary to create a tangible Spirit of the Times.

 * Descartes was far more subtle about mind-and-body interactions than many crude commentators admit, but he was right that thoughts don't seem to take up any room, not even in one's head. What are they? No one knows. No one really knows what a thought is. It must involve the chemicals and the synapses, of course, but how do the words and pictures come into it?

J

 * Today's banalities apparently gain in profundity if one states that the wisdom of the past, for all its virtues, belongs to the past. The arrogance of those who come later preens itself with the notion that the past is dead and gone. … The modern mind can no longer think thought, only can locate it in time and space. The activity of thinking decays to the passivity of classifying.

 * Immaturity is the incapacity to use one's intelligence without the guidance of another. Such immaturity is self-caused if it is not caused by lack of intelligence, but by lack of determination and courage to use one's intelligence without being guided by another. Sapere Aude! Have the courage to use your own intelligence!

 * All existential problems are passionate problems, for when existence is interpenetrated with reflection, it generates passion. To think about existential problems in such a way as to leave out the passion is tantamount to not thinking about them at all, since it is to forget the point, which is that the thinker himself is an existing individual.
 * Søren Kierkegaard, Concluding Unscientific Postscript, p. 313


 * The history of human thought recalls the swinging of a pendulum which takes centuries to swing. After a long period of slumber comes a moment of awakening. Then thought frees herself from the chains with which those interested — rulers, lawyers, clerics — have carefully enwound her. She shatters the chains. She subjects to severe criticism all that has been taught her, and lays bare the emptiness of the religious, political, legal, and social prejudices amid which she has vegetated. She starts research in new paths, enriches our knowledge with new discoveries, creates new sciences.

 * A century ago, we had essentially no way to start to explain how thinking works. Then psychologists like Sigmund Freud and Jean Piaget produced their theories about child development. Somewhat later, on the mechanical side, mathematicians like Kurt Gödel and Alan Turing began to reveal the hitherto unknown range of what machines could be made to do. These two streams of thought began to merge only in the 1940s, when Warren McCulloch and Walter Pitts began to show how machines might be made to see, reason, and remember. Research in the modern science of Artificial Intelligence started only in the 1950's, stimulated by the invention of modern computers. This inspired a flood of new ideas about how machines could do what only minds had done previously.
 * Marvin Minsky, The Society of Mind (1988)


 * What is the difference between merely knowing (or remembering, or memorizing) and understanding? We all agree that to understand something, we must know what it means... A thing or idea seems meaningful only when we have several different ways to represent it–different perspectives and different associations. Then we can turn it around in our minds, so to speak: however it seems at the moment, we can see it another way and we never come to a full stop. In other words, we can 'think' about it. If there were only one way to represent this thing or idea, we would not call this representation thinking.

 * Man is but a reed, the most feeble thing in nature, but he is a thinking reed. The entire universe need not arm itself to crush him. A vapor, a drop of water suffices to kill him. But, if the universe were to crush him, man would still be more noble than that which killed him, because he knows that he dies and the advantage which the universe has over him; the universe knows nothing of this. All our dignity consists then in thought. By it we must elevate ourselves, and not by space and time which we cannot fill. Let us endeavor to think well; this is the principle of morality.

 * The book of new discoveries and the light of daring is open before humanity, and you have already heard about the approach of the New Era. Every epoch has its Call, and the calling foundation of the New Era will be the power of thought. That is why we call you to understand the great significance of creative thought, and the first step in this direction will be the opening of consciousness, freedom from all prejudices and from all tendentiousness and forced concepts.Let us glance at the entire immensity of the night sky. In our thoughts let us fly over the innumerable worlds and the hidden depths of infinite space. Thought in its substance is infinite, and only our consciousness attempts to limit it. Therefore, without delay, let us start the next step—broadening of consciousness. The most ancient wisdom of India says: “Thought is the primary source of world creation.” The Great Buddha pointed out the meaning of thought which builds our essence. He taught his pupils to broaden their consciousness. Lao Tze, Confucius, Christ —all Teachers of spirit and great thinkers taught the same thing.
 * Helena Roerich in Letters of Helena Roerich, Volume I: 1929-1935 (1940)


 * The Great Plato said: “Thoughts rule the world.” And modern scientists, as for instance Professor Compton, have expressed the probability of an active, rational force in every phenomenon of nature, and of the influence of thought upon matter. He concludes with the following remarkable words: “Possibly the thoughts of men are the most important factors in the world.”  With such broad understanding let us become acquainted with the history of the development of thought. Putting aside all prejudices of place, time and nationality, we, like the bees, shall collect the precious honey of human creative thought!   After placing into the foundation the powerful achievements of those great creators who molded our consciousness, let us begin the third step—the development of our own thought, our own creativeness; and from the new combinations we shall hew sparks of the fire of thought, this crown of the Universe.
 * Helena Roerich in Letters of Helena Roerich, Volume I: 1929-1935 (1940)


 * Let us remember that a thinking being is never lonely because thought is his greatest magnet and brings similar response from space. Therefore, if we want to receive a beautiful answer we should send into vibrating space our striving thoughts saturated with the pure fire of the heart; only the thought which is spiritualized by striving, nourished by the heart, can create and attract as a powerful magnet. Thought without the striving and flaming quality is sterile. Thus, let us long for knowledge, for broad thoughts, and in our striving we shall dare, as only daring thought molds new ways.
 * Helena Roerich in Letters of Helena Roerich, Volume I: 1929-1935 (1940)


 * We all have a tendency to think that the world must conform to our prejudices. The opposite view involves some effort of thought, and most people would die sooner than think — in fact they do so.

 * It is what a man has thought out directly for himself that alone has true value. Thinkers may be classed as follows: those who, in the first place, think for themselves, and those who think directly for others. The former thinkers are the genuine, they think for themselves in both senses of the word; they are the true philosophers; they alone are in earnest. Moreover, the enjoyment and happiness of their existence consist in thinking. The others are the sophists; they wish to seem, and seek their happiness in what they hope to get from other people; their earnestness consists in this.
 * Arthur Schopenhauer, “Thinking for Oneself,” H. Dirks, trans.


 * The characteristic sign of a mind of the highest standard is the directness of its judgment. Everything it utters is the result of thinking for itself; this is shown everywhere in the way it gives expression to its thoughts. Therefore it is, like a prince, an imperial director in the realm of intellect. All other minds are mere delegates, as may be seen by their style, which has no stamp of its own. Hence every true thinker for himself is so far like a monarch; he is absolute, and recognises nobody above him. His judgments, like the decrees of a monarch, spring from his own sovereign power and proceed directly from himself. He takes as little notice of authority as a monarch does of a command; nothing is valid unless he has himself authorised it. On the other hand, those of vulgar minds, who are swayed by all kinds of current opinions, authorities, and prejudices, are like the people which in silence obey the law and commands.

 * I am credited with being one of the hardest workers and perhaps I am, if thought is the equivalent of labour, for I have devoted to it almost all of my waking hours. But if work is interpreted to be a definite performance in a specified time according to a rigid rule, then I may be the worst of idlers. Every effort under compulsion demands a sacrifice of life-energy. I never paid such a price. On the contrary, I have thrived on my thoughts.

 * “I cannot live with myself any longer.” This was the thought that kept repeating itself in my mind. Then suddenly I became aware of what a peculiar thought it was. “Am I one or two? If I cannot live with myself, there must be two of me: the ‘I’ and the ‘self’ that ‘I’ cannot live with.” “Maybe,” I thought, “only one of them is real.”
 * Eckhart Tolle, The Power of Now (1997)


 * Thinking has become a disease. Disease happens when things get out of balance... The mind is a superb instrument if used rightly. Used wrongly, however, it becomes very destructive. To put it more accurately, it is not so much that you use your mind wrongly - you usually don't use it at all. It uses you. This is the disease. You believe that you are your mind. This is the delusion. The instrument has taken you over.
 * Eckhart Tolle, The Power of Now (1997) p. 16


 * Just because you can solve a crossword puzzle or build an atom bomb doesn't mean that you use your mind. Just as dogs love to chew bones, the mind loves to get its teeth into problems. That's why it does crossword puzzles and builds atom bombs. You have no interest in either. Let me ask you this: can you be free of your mind whenever you want to? Have you found the "off" button?... You mean stop thinking altogether? No, I can't, except maybe for a moment or two... Then the mind is using you. You are unconsciously identified with it, so you don't even know that you are its slave. It's almost as if you were possessed without knowing it, and so you take the possessing entity to be yourself. The beginning of freedom is the realization that you are not the possessing entity - the thinker. Knowing this enables you to observe the entity.
 * Eckhart Tolle, The Power of Now (1997) p. 16


 * The good news is that you can free yourself from your mind. This is the* only true liberation. You can take the first step right now. Start listening to the voice in your head as often as you can... When you listen to that voice, listen to it impartially. That is to say, do not judge. Do not judge or condemn what you hear, for doing so would mean that the same voice has come in again through the back door. You'll soon realize: there is the voice, and here I am listening to it, watching it. This I am realization, this sense of your own presence, is not a thought. It arises from beyond the mind... When you listen to a thought, you are aware not only of the thought but also of yourself as the witness of the thought. A new dimension of consciousness has come in.
 * Eckhart Tolle, The Power of Now (1997) p. 17


 * I am not my thoughts, emotions, sense perceptions, and experiences. I am not the content of my life. I am Life. I am the space in which all things happen. I am consciousness. When you look at a tree, you are aware of the tree. When you have a thought or feeling, you are aware of that thought or feeling. When you have a pleasurable or painful experience, you are aware of that experience. These seem to be true and obvious statements. Yet if you look at them very closely, you will find that in a subtle way their very structure contains a fundamental illusion, an illusion which is unavoidable when you use language. Thought and language create an apparent duality and a separate person where there is none. The truth is you are not somebody who is aware of the tree, the thought, feeling or experience. You are the awareness or consciousness in and by which those things appear. As you go about your life, can you be aware of yourself as the awareness in which the entire content of your life unfolds?
 * Eckhart Tolle,  Stillness Speaks (2003)


 * There is an aliveness in you that you can feel with your Being, not just in the head. Every cell is alive in that presence in which you don't need to think. Yet, in that state, if thought is required for some practical purpose, it is there. The mind can still operate, and it operated beautifully when the greater intelligence that you are uses it and expresses itself through it.
 * Eckhart Tolle,  Stillness Speaks (2003)


 * Many people live with a tormentor in their head that continuously attacks and punishes them and drains them of vital energy. It is the cause of untold misery and unhappiness, as well as of disease. The good news is that you can free yourself from your mind. This is the only true liberation. You can take the first step right now. Start listening to the voice in your head as often as you can. Pay particular attention to any repetitive thought patterns, those old gramophone records that have been playing in your head perhaps for many years. This is what I mean by "watching the thinker," which is another way of saying: listen to the voice in your head, be there as the witnessing presence.  When you listen to that voice, listen to it impartially. That is to say, do not judge. Do not judge or condemn what you hear, for doing so would mean that the same voice has come in again through the back door. You'll soon realize: there is the voice, and here I am listening to it, watching it. This I am realization, this sense of your own presence, is not a thought. It arises from beyond the mind.
 * Eckhart Tolle in A New Earth: Awakening to Your Life's Purpose, p. 17, (2005)


 * The predominance of mind is no more than a stage in the evolution of consciousness. We need to go on to the next stage now as a matter of urgency; otherwise, we will be destroyed by the mind, which has grown into a monster. I will talk about this in more detail later. Thinking and consciousness are not synonymous. Thinking is only a small aspect of consciousness. Thought cannot exist without consciousness, but consciousness does not need thought. Enlightenment means rising above thought, not falling back to a level below thought, the level of an animal or a plant. In the enlightened state, you still use your thinking mind when needed, but in a much more focused and effective way than before.
