If we take an unprejudiced view of the processes of consciousness, free from all the so-called association rules and theories, we see at once that an idea is no more an even relatively constant thing than is a feeling or emotion or volitional process. There exist only changing and transient ideational processes ; there are no permanent ideas that return again and disappear again.

Ideas, unlike solid structures, do not perish. They remain immortal, immaterial and everywhere, like all Divine things. Ideas are a golden, savage landscape that we wander unaware, without a map. Be careful: in the last analysis, reality may be exactly what we think it is.

An idea is like a virus. Resilient. Highly contagious. The smallest seed of an idea can grow. It can grow to define...or destroy you.

Thought is an Idea in transit, which when once released, never can be lured back, nor the spoken word recalled. Nor ever can the overt act be erased.

Some words shall herein be capitalised when used, not as vernacular, but as terms defined. Thus an "idea" is the substance of an actual unitary thought or fancy; but "Idea," nearer Plato's idea of ἰδέα, denotes anything whose Being consists in its mere capacity for getting fully represented, regardless of any person's faculty or impotence to represent it.

[I]s this not an advantage? Is it not a sign of immense progress that the masses should have "ideas," that is to say, should be cultured? By no means. The "ideas" of the average man are not genuine ideas, nor is their possession culture. An idea is a putting truth in checkmate. Whoever wishes to have ideas must first prepare himself to desire truth and to accept the rules of the game imposed by it. It is no use speaking of ideas when there is no acceptance of a higher authority to regulate them, a series of standards to which it is possible to appeal in a discussion. These standards are the principles on which culture rests.

To say that everything is idea or that everything is spirit, is the same as saying that everything is matter or that everything is energy, for if everything is idea or spirit, just as my consciousness is, it is not plain why the diamond should not endure for ever, if my consciousness, because it is idea or spirit, endures forever.

What distinct meaning can attach to saying that an idea in the past in any way affects an idea in the future, from which it is completely detached?

At first our pupil had merely sensations, now he has ideas; he could only feel, now he reasons. For from the comparison of many successive or simultaneous sensations and the judgment arrived at with regard to them, there springs a sort of mixed or complex sensation which I call an idea. The way in which ideas are formed gives a character to the human mind. The mind which derives its ideas from real relations is thorough; the mind which relies on apparent relations is superficial. He who sees relations as they are has an exact mind; he who fails to estimate them aright has an inaccurate mind; he who concocts imaginary relations, which have no real existence, is a madman; he who does not perceive any relation at all is an imbecile. Clever men are distinguished from others by their greater or less aptitude for the comparison of ideas and the discovery of relations between them. Simple ideas consist merely of sensations compared one with another. Simple sensations involve judgments, as do the complex sensations which I call simple ideas. In the sensation the judgment is purely passive; it affirms that I feel what I feel. In the percept or idea the judgment is active; it connects, compares, it discriminates between relations not perceived by the senses. That is the whole difference; but it is a great difference. Nature never deceives us; we deceive ourselves.

There is no word or action but has its echo in Eternity. Thought is an Idea in transit, which when once released, never can be lured back, nor the spoken word recalled. Nor ever can the overt act be erased All that thou thinkest, sayest, or doest bears perpetual record of itself, enduring for Eternity.

The only difference between image and idea is thus that in the one case, the expression of the object is confused, and in the other, it is clear. The confusion comes from this: every movement envelops in itself the infinity of the movements of the universe; and the brain receives an infinity of modifications to which only a confused thought can correspond, enveloping the infinity of clear ideas that would correspond to each detail. Clear ideas are therefore contained in the confused ideas. They are unconscious; they are perceived without being apperceived. Only their sum total is apperceived; this appears simple to us because of our ignorance of its components.

"An idea is inevitably a coordination. It is a coming together of something that is separate or disorganized or incomplete. With an idea you begin to feel into the nature of that incompleteness.

"Nature and Idea" December 30, 1956"

An idea is a point of departure and no more. As soon as you elaborate it, it becomes transformed by thought

Statues of brass and marble will perish; and statues made in imitation of them are not the same statues, nor the same workmanship, any more than the copy of a picture is the same picture. But print and reprint a thought a thousand times over, and that with materials of any kind, carve it in wood, or engrave it on stone, the thought is eternally and identically the same thought in every case. It has a capacity of unimpaired existence, unaffected by change of matter, and is essentially distinct, and of a nature different from every thing else that we know of, or can conceive. If then the thing produced has in itself a capacity of being immortal, it is more than a token that the power that produced it, which is the self-same thing as consciousness of existence, can be immortal also; and that as independently of the matter it was first connected with, and as the thought is of the printing or writing it first appeared in.
