Joseph Kosuth, 1965.
This is one of my favorite (and very popular) conceptual art pieces. Not only was this from a radical new perspective, but deliberatley procative art is already stimulating. One and Three Chairs is essentially an argument. Kosuth places an actual chair against a wall. To its left hangs a dry, documentary-like photograph of that chair, and to its right, a blown up photocopied text panel is to be placed; a dictionary definition of “chair.” It rlly makes obvious how we (the general person) overly focuses on visuals. I battle the possibilities and meanings conveyed. I still question myself when I see it. It's highly intellectually engaging. And of course I love this, it refers to Plato's Forms, in Plato's Republic (Book X).
Joseph Kosuth was 20 years old when he put this together.
