... a snapshot of a thing, of a nothing, really ---- a ball in the air, a guy in a T-shirt standing in a nowhere street, a Volvo, whatever ---- cool. Anything could be cool as long as you didn't try to exert too much influence over it. Cool is the art of not appearing to try too hard ---- or to care too much. That neutrality, feigned or otherwise, would come to embody a generation's wishful relationship to the trashy world that is our visual culture, like one long episode of the old Route 66 TV show, which was about life as seen from a passing car.
Adapted from David Salle's "The Petite Cinema of John Baldessari"
... a word we use to describe anything we find intriguing or unique – something or someone that catches our eye and tests the depths of self-expression and imagination that we commonly confine ourselves to.
