“I shall call modern that art which ... presents the fact that the unpresentable exists. To make visible that there is something which can be conceived and which can neither be seen nor made visible.”

“All there is to thinking is seeing something noticeable which makes you see something you weren't noticing which makes you see something that isn't even visible.”

“The abstract idea of a spirit certainly implies that it has neither substance, form, shape, voice, or anything which can render its presence visible or sensible to human faculties.”

“Neither in environment nor in heredity can I find the exact instrument that fashioned me, the anonymous roller that pressed upon my life a certain intricate watermark whose unique design becomes visible when the lamp of art is made to shine through life's foolscap.”

“...and that visibility which makes us most vulnerable is that which also is the source of our greatest strength.”

“Art does not reproduce the visible; it makes visible.”
