“Works of art are analytic propositions. That is, if viewed within their context – as art – they provide no information whatsoever about any matter of fact. A work of art is a tautology in that it is a presentation of the artist’s intention, that is, he is saying that that particular work of art is art, which means, is a definition of art.”

version in Dutch (citaat van Israëls, in het Nederlands): Ik geloof niet in joodse kunst. Er zijn joodse kunstenaars, d.w.z. kunstenaars die joods geboren zijn, maar dat wil nog niet zeggen dat hun werk joodse kunst is.

The Soul of Man Under Socialism (1891)
Context: If a man approaches a work of art with any desire to exercise authority over it and the artist, he approaches it in such a spirit that he cannot receive any artistic impression from it at all. The work of art is to dominate the spectator: the spectator is not to dominate the work of art. The spectator is to be receptive. He is to be the violin on which the master is to play. And the more completely he can suppress his own silly views, his own foolish prejudices, his own absurd ideas of what Art should be, or should not be, the more likely he is to understand and appreciate the work of art in question.

Context: Business art is the step that comes after Art. I started as a commercial artist, and I want to finish as a business artist. After I did the thing called 'art' or whatever it's called, I went into business art. I wanted to be an Art Businessman or a Business Artist. Being good in business is the most fascinating kind of art. During the hippies era people put down the idea of business – they'd say 'Money is bad', and 'Working is bad', but making money is art and working is art and good business is the best art.
