The differences in intentionality
[Marc] Treib summarized Irwin's views on conditional art as follows: "One does not start with a personal vocabulary or manner to be adapter to each situation. Thus, given the differences in intentionality between art and design, the artist and the designer will 'plow different furrows seemingly in the same field.'" This is an important point since it gets at the difference that Irwin sees between art and design, the first of which is predicated, as he says, on the opportunity to deal with each situation freely and without constraints, and the latter, which is restricted in many ways from the outset by functional, stylistic, and economic concerns.
