The camera introduces us to unconscious optics as does psychoanalysis to unconscious impulses.
— Walter Benjamin

Music is the arithmetic of sounds as optics is the geometry of light.
Claude Debussy optic quote

At the heart of the debate over intelligent design is this question: Can a scientific explanation of the history of life include the actions of an unseen higher being? The proponents of intelligent design, a school of thought that some have argued should be taught alongside evolution in the nation's schools, say that the complexity and diversity of life go beyond what evolution can explain.Biological marvels like the optical precision of an eye, the little spinning motors that propel bacteria and the cascade of proteins that cause blood to clot, they say, point to the hand of a higher being at work in the world.
— Kenneth Chang

Marijuana is a useful catalyst for specific optical and aural aesthetic perceptions. I apprehended the structure of certain pieces of jazz and classical music in a new manner under the influence of marijuana, and these apprehensions have remained valid in years of normal consciousness.
— Allen Ginsberg

Education at school continues what has been done at home: it crystallizes the optical illusion, consolidates it with book learning, theoretically legitimizes the traditional trash and trains the children to know without understanding and to accept denominations for definitions. Astray in his conceptions, entangled in words, man loses the flair for truth, the taste for nature. What a powerful intellect must you possess, to be suspicious of this moral carbon dioxide and with your head swimming already, to hurl yourself out of it into the fresh air, with which, into the bargain, everyone round is trying to scare you!
— optic quotation by Alexander Herzen
