René Magritte said this quote

As regards the artists themselves, most of them gave up their freedom quite lightly, placing their art at the service of someone or something. As a rule, their concerns and their ambitions are those of any old careerist. I thus acquired a total distrust of art and artists, whether they were officially recognised or were endeavouring to become so, and I felt that I had nothing in common with this guild. I had a point of reference which held me elsewhere, namely that magic within art which I had encountered as a child.
