I feel shame, not for the wrong things I have done, but for the right things that I have failed to do. - Marcel Duchamp

..Yes, indeed, what have we been up to? I feel rather like I've retired to the country, in some remote province, for that's what my life is like in N. Y. I see few people and people don’t try to see me anymore as they know they bore me. I write to the Arensberg's once a year and they do the same. There is a general weariness which, I think, is not confined to our generation. To tell the truth, most people prefer war to peace.. .Well, there you are, my dear Yvonne. Nothing as usual. Chess as much as possible: at least chess players don’t talk -

I realized very soon the danger of repeating indiscriminately this form of expression and decided to limit the production of 'ready-mades' to a small number yearly. I was aware at that time, that for the spectator even more than for the artist, art is a habit forming drug and I wanted to protect my 'ready-mades' against such contamination.

All in all, the creative act is not performed by the artist alone.. the spectator brings the work in contact with the external world by deciphering and interpreting its inner qualifications and thus adds his contribution to the creative act.
