"There can be no doubt that Tsai's phenomena (whether they be works of art in the strict sense, or whether they be fantastic artifices) are extremely important. They show what promises and dangers may be in here in a "play," if it is proposed by a great artist. Because, even if Tsai's phenomena be considered artifices, there can be no doubt that Tsai is a great artist. Not because what he does is pleasant, or because he proposes a play, or because he represents the spirit of our times, but because he reveals to us, through artifice or works of art, the concrete experience of a future full of promise or abysmal danger."

"The photographer’s gesture as the search for a viewpoint onto a scene takes place within the possibilities offered by the apparatus. The photographer moves within specific categories of space and time regarding the scene: proximity and distance, bird- and worm’s-eye views, frontal- and side-views, short or long exposures, etc. The Gestalt of space–time surrounding the scene is prefigured for the photographer by the categories of his camera. These categories are an a priori for him. He must ‘decide’ within them: he must press the trigger."
