“The interesting thing is what happens in the specific picture: its precision in terms of the sensations it produces — the illusion it creates and the effect of this illusion on the psychology opposed to it.”

“Since one cannot create 'depth' by carving a hole in the picture, and since one should not attempt to create the illusion of depth by tonal gradation, depth as a plastic reality must be two dimensions in a formal sense as well in the sense of color. 'Depth' is not created on a flat surface as an illusion, but as a plastic reality. The nature of the picture plane makes it possible to achieve depth without destroying the two-dimensional essence of the picture plane.. A plane is a fragment in the architecture of space. When a number of planes are opposed one to another, a spatial effect results. A plane functions in the same manner as the walls of a building... Planes organized within a picture create the pictorial space of its composition... The old masters were plane-consciousness. This makes their pictures restful as well as vital…”

“All spiritual practices are illusions created by illusionists to escape illusion.”

“For in the Spirit-World there is Reality; as the process of differentiation proceeds, illusion is produced, and it is this mind, this growing mind, that makes the illusion. It is this growing mind that has endless images and pictures, that has the image-making faculty which we speak of as imagination, that has the reasoning faculty which builds on the airy picture that it has made— it is this which is the real creator of illusion, it is this which slays the Real, so far as the disciple is concerned, and his first work as disciple will be to slay the slayer.”

“Most of us, no matter what we say, are walking in the dark, whistling in the dark. Nobody knows what is going to happen to him from one moment to the next, or how one will bear it. This is irreducible. And it's true of everybody. Now, it is true that the nature of society is to create, among its citizens, an illusion of safety; but it is also absolutely true that the safety is always necessarily an illusion. Artists are here to disturb the peace.”

“In this precise sense, Kant was "the inventor of the philosophical history of philosophy": there are necessary stages in the development of philosophy, that is, one cannot directly get at the truth, one cannot begin wit it, philosophy necessarily began with metaphysical illusions. The path from illusion to its critical denunciation is the very core of philosophy, which means that successful ("true") philosophy is no longer defined by its truthful explanation of the totality of being, but by successfully accounting for the illusions, that is, by explaining not only why illusions are illusions, but also why they are structurally necessary, unavoidable, and not just accidents.”

“Love is a simple thing and a deep thing: it is an act of life and not an illusion. Art is an illusion.”

“The fact that man produces a concept "I" besides the totality of his mental and emotional experiences or perceptions does not prove that there must be any specific existence behind such a concept. We are succumbing to illusions produced by our self-created language, without reaching a better understanding of anything. Most of so-called philosophy is due to this kind of fallacy.”

“We create the illusions we need to go on.”

“Progress is not an illusion; it happens, but it is slow and invariably disappointing.”
