The source of genius is imagination alone.

The outcome of my days is always the same; an infinite desire for what one never gets; a void one cannot fill; an utter yearning to produce in all ways, to battle as much as possible against time that drags us along, and the distractions that throw a veil over our soul.

All painting worth its name, unless one is talking about black and white, must include the idea of color as one of its necessary supports, in the same way that it includes chiaroscuro, proportion, and perspective.

Real beauty in the arts is eternal and would be accepted at all periods; but it wears the dress of its century: something of that dress clings to it, and woe to the works which appear in periods when the general taste is corrupted.

A taste for simplicity cannot last for long.

The secret of not having worries, for me at least, is to have ideas.

Talent does whatever it wants to do. Genius does only what it can.
