Excerpts From Speculation (1967-1970)
Mel Bochner
For a variety of reasons I do not like the term “conceptual art.” Connotations of an easy dichotomy with perception are obvious and inappropriate. The unfortunate implication is of a somewhat magical/mystical leap from one mode of existence to another. The problem is the confusion of idealism and intention. By creating an original fiction, “conceptualism” posits its special nonempirical existence as a positive (transcendent) value. But no amount of qualification (or documentation) can change the situation. Outside the spoken word, no thought can exist without a sustaining support.
