“And when they encounter works of art which show that using new media can lead to new experiences and to new consciousness, and expand our senses, our perception, our intelligence, our sensibility, then they will become interested in this music.”

Vague Thoughts On Art (1911)
Context: I cannot help thinking that historians, looking back from the far future, will record this age as the Third Renaissance. We who are lost in it, working or looking on, can neither tell what we are doing, nor where standing; but we cannot help observing, that, just as in the Greek Renaissance, worn-out Pagan orthodoxy was penetrated by new philosophy; just as in the Italian Renaissance, Pagan philosophy, reasserting itself, fertilised again an already too inbred Christian creed; so now Orthodoxy fertilised by Science is producing a fresh and fuller conception of life — a love of Perfection, not for hope of reward, not for fear of punishment, but for Perfection's sake. Slowly, under our feet, beneath our consciousness, is forming that new philosophy, and it is in times of new philosophies that Art, itself in essence always a discovery, must flourish. Those whose sacred suns and moons are ever in the past, tell us that our Art is going to the dogs; and it is, indeed, true that we are in confusion! The waters are broken, and every nerve and sinew of the artist is strained to discover his own safety. It is an age of stir and change, a season of new wine and old bottles. Yet, assuredly, in spite of breakages and waste, a wine worth the drinking is all the time being made.

The Believer interview (2013)
Context: Yeah, our view of reality, the one we conventionally take, is one among many. It’s pretty much a fact that our entire universe is a mental construct. We don’t actually deal with reality directly. We simply compose a picture of reality from what’s going on in our retinas, in the timpani of our ears, and in our nerve endings. We perceive our own perception, and that perception is to us the entirety of the universe. I believe magic is, on one level, the willful attempt to alter those perceptions. Using your metaphor of an aperture, you would be widening that window or changing the angle consciously, and seeing what new vistas it affords you.

Against Interpretation and Other Essays (1966)
Context: Art today is a new kind of instrument, an instrument for modifying consciousness and organizing new modes of sensibility. And the means for practicing art have been radically extended.... Painters no longer feel themselves confined to canvas and paint, but employ hair, photographs, wax, sand, bicycle tires, their own toothbrushes and socks. Musicians have reached beyond the sounds of the traditional instruments to use tampered instruments and (usually on tape) synthetic sounds and industrial noises.
