A person who thinks by images becomes less and less capable of thinking by reasoning, and vice versa. The intellectual process based on images is contradictory to the intellectual process of reasoning that is related to the word. There are two different ways of dealing with an object. They involve not only different approaches, but even more important, opposing mental attitudes. This is not a matter of complementary processes, such as analysis and synthesis or logic and dialectic. These processes lack any qualitative common denominator.

If I should try to put it into words, I mean how I did see her, it would be incomprehensible, for the simple reason that I find that I never did have a really clear idea of her at any time. I had an image of her, but that is not the same thing. An image is a stop the mind makes between uncertainties. I had gathered, of course, a good deal from you, and later, after she went away, from others, but this only strengthened my confusion. The more we learn of a person, the less we know.

We are accustomed to speak of ideas as reproduced, as passed from mind to mind, as similar or dissimilar to one another, and, in short, as if they were substantial things; nor can any reasonable objection be raised to such expressions. But taking the word "idea" in the sense of an event in an individual consciousness, it is clear that an idea once past is gone forever, and any supposed recurrence of it is another idea. These two ideas are not present in the same state of consciousness, and therefore cannot possibly be compared.

Pictures are the idea in visual or pictorial form; and the idea has to be legible, both in the individual picture and in the collective context – which presupposes, of course, that words are used to convey information about the idea and the context. However, none of this means that pictures function as illustrations of an idea: ultimately, they are the idea. Nor is the verbal formulation of the idea a translation of the visual: it simply bears a certain resemblance to the meaning of the idea. It is an interpretation, literally a reflection.

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.

But let it be considered that hardly anything can strike the mind with its greatness, which does not make some sort of approach towards infinity; which nothing can do whilst we are able to perceive its bounds; but to see an object distinctly, and to perceive its bounds, is one and the same thing. A clear idea is therefore another name for a little idea.

Image…that which presents an intellectual and emotional complex in an instant of time.

An image means nothing. It is just a door, leading to the next door. It will never happens that we will find the truth we are looking for just in an image; it will happen behind the last door that the spectator discover the truth, because of his own efforts.

...for each of us sees clarity only in those ideas which have the same degree of confusion as his own.

Idea or Vision, in its sensuous meaning, would be something that could be perceived only by the bodily eye and not by any other sense such as taste, hearing, etc.; it would be such a thing as a rainbow, or the forms which pass before us in dreams. Idea or Vision, in its supersensuous meaning, would denote, first of all, in conformity with the sphere in which the word is to be valid, something that cannot be perceived by the body at all, but only by the mind; and then, something that cannot, as many other things can, be perceived by the dim feeling of the mind, but only by the eye of the mind, by clear perception.

The mind is hurried out of itself, by a crowd of great and confused images; which affect because they are crowded and confused. For separate them, and you lose much of the greatness; and join them, and you infallibly lose the clearness. [...] But painting, when we have allowed for the pleasure of imitation, can only affect simply by the images it presents; and even in painting, a judicious obscurity in some things contributes to the effect of the picture; because the images in painting are exactly similar to those in nature; and in nature, dark, confused, uncertain images have a greater power on the fancy to form the grander passions, than those have which are more clear and determinate. But where and when this observation may be applied to practice, and how far it shall be extended, will be better deduced from the nature of the subject, and from the occasion, than from any rules that can be given.

Image is psyche.

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.

Images are defined to be information structures, with different kind of images representing different kind of information about what the actor is doing, why and how, and what kind of progress is being made.
