Conceptual artist Joseph Kosuth has spent six decades treating language as the content and subject of art. I Shall Offer It To You As A Ready-Made Product at Castelli Gallery centers on his decade-long dialogue with Freud, with neon reproductions of handwritten annotations, negated sentences, and fetishism turned back on itself. Alongside Proto-Investigations from 1965 and Lewis Carroll logic games, the exhibition reveals the enduring sense of play embedded in Kosuth's philosophical inquiry.
