To say that a thing is beautiful is simply an act of faith, not a measurement on some kind of scale. - Édouard Vuillard

We perceive nature through the senses, which give us images of forms of colour, sounds etc. A form which exists only in relation to another form on its own, it does not exist.

Nothing is important save the spiritual state that enables one to subjectify one's thoughts to a sensation and to think only of the sensation, all the while searching to express it.

Conceive of a picture really as a series of harmonies.
