"In 1946, when I was still an adolescent, I went and signed my name on the other side of the sky during a fantastic realistico-imaginary voyage."
"Blue has no dimensions, it is beyond dimensions, whereas the other colours are not. They are pre-psychological expanses, red, for example, presupposing a site radiating heat.. .All colours arouse specific associative ideas, psychologically material or tangible, while blue suggests at most the sea and sky, and they, after all, are in actual, visible nature what is most abstract."

Yves Klein was a French artist and an important figure in post-war European art. He was a leading member of the French artistic movement of Nouveau réalisme, founded in 1960 by art critic Pierre Restany. Klein was a pioneer in the development of performance art, and is seen as an inspiration to and as a forerunner of minimal art, as well as pop art. He developed and used International Klein Blue.
"In 1946, when I was still an adolescent, I went and signed my name on the other side of the sky during a fantastic realistico-imaginary voyage."
"It was in 1947 that the idea of a conscious monochrome vision came to me.. .Pure, existential space was regularly winking at me, each time in a more impressive manner, and this sensation of total freedom attracted me so powerfully that I painted some monochrome surfaces just to see, to see with my own eyes what existential sensibility granted me; absolute freedom! But each time I could neither imagine or think of the possibility of considering this as a painting, a picture, until the day when I said: Why not?"
"It was pure chance that led me to judo. Judo has helped me to understand that pictorial space is above al the product of spiritual exercises. Judo is in fact the discovery by the human body of a spiritual space."
"Dubbed as a Knight of the Order of Saint Sebastian, I espoused the cause of pure colour, which has been invaded by guile, occupied and oppressed in cowardly fashion by line and its manifestation; drawing in Art. I aimed to defend and deliver it, and lead it to triumph and final glory."
"I was trying to show colour, but I realized at the private view that the public were prisoners of a preconceived point of view and that, confronted with all these surfaces of different colours, they responded far more to the inter-relationship of the different propositions, they reconstituted the elements of a decorative polychromy."
"..the thinking man is no longer the center of the universe, but the universe is the center of the man [referring to collaborations between artists, in which Klein was involved several times]. We shall then know prestige in comparison to the vertigo of before. Thus we shall become men of the air, we shall know the upward force of attraction, towards space, towards nowhere and everywhere at once; having thus mastered the earthly force of attraction we shall literally levitate in complete physical and spiritual freedom."
"Now Art, used collectively for painting, sculpture, architecture and music, is the mediatress between, and reconciler of, nature and man. It is, therefore, the power of humanizing nature, of infusing the thoughts and passions of man into everything which is the object of his contemplation."
"The Good consists in the congruity of a thing with the laws of the reason and the nature of the will, and in its fitness to determine the latter to actualize the former: and it is always discursive. The Beautiful arises from the perceived harmony of an object, whether sight or sound, with the inborn and constitutive rules of the judgment and imagination: and it is always intuitive."
"I believe that the unity of man as opposed to other living things derives from the fact that man is the conscious life of himself. Man is conscious of himself, of his future, which is death, of his smallness, of his impotence; he is aware of others as others; man is in nature, subject to its laws even if he transcends it with his thought."
"Who made you glorious as the gates of heaven Beneath the keen full moon? Who bade the sun Clothe you with rainbows? Who, with living flower Of loveliest blue, spread garlands at your feet? God! let the torrents, like a shout of nations, Answer! and let the ice-plains echo, God! God! sing, ye meadow-streams, with gladsome voice! Ye pine-groves, with your soft and soul-like sounds! And they too have a voice, yon piles of snow, And in their perilous fall shall thunder, God!"
"All Nature seems at work. Slugs leave their lair — The bees are stirring — birds are on the wing — And Winter slumbering in the open air, Wears on his smiling face a dream of Spring! And I the while, the sole unbusy thing, Nor honey make, nor pair, nor build, nor sing."
"Taste is the intermediate faculty which connects the active with the passive powers of our nature, the intellect with the senses; and its appointed function is to elevate the images of the latter, while it realizes the ideas of the former."
