I too was filled with a sort of shyness and fear, as I was called to leave 'the world of will and idea' in which I had lived and created, and in whose reality I had believed. But the happy liberating touch of non-objectivity drew me out into the 'desert' where only feeling is real.... and so feeling became the content of my life. It was no 'empty square' I had exhibited but the feeling of non-objectivity. I perceived that the 'thing' and the 'idea' were taken to be equivalents of feeling, and understood the lie of the world of will and idea. Is the milk bottle the symbol of milk? Suprematism is the rediscovery of that pure art which in the course of time, and by an accretion of 'things', had been lost to sight.
