“Art is science made clear.”

“Every artist was first an amateur.”

“No man but a blockhead ever wrote, except for money.”

“Pictures deface walls oftener than they decorate them.”

“I don't want life to imitate art. I want life to be art.”

“Boredom is always counter-revolutionary. Always.”

“Quotations are useful in periods of ignorance or obscurantist beliefs.”

“Tourism, human circulation considered as consumption is fundamentally nothing more than the leisure of going to see what has become banal.”

“In societies where modern conditions of production prevail, all of life presents itself as an immense accumulation of spectacles. Everything that was directly lived has moved away into a representation.”

“There is nothing more natural than to consider everything as starting from oneself, chosen as the center of the world; one finds oneself thus capable of condemning the world without even wanting to hear its deceitful chatter.”

“Ideas improve. The meaning of words participates in the improvement. Plagiarism is necessary. Progress implies it. It embraces an author's phrase, makes use of his expressions, erases a false idea, and replaces it with the right idea.”
