SIGMAR POLKE, Fotografien (Edition Cantz, Stuttgart 1990)

"Polke's experiments with photo-chemicals dematerialise the reality of photographic representation, and point to his later concern with 'cosmic' forces and emanations (...) Polke's rearrangements of matter, his materialist excesses and nonlogical operations are aimed at transgressing the laws of the scientific universe and at reinstating the sovreignty of man as 'homo ludens'." (from my article, 'How to make gold from shit', Perspektief 42, Rotterdam 1991)
