Dear Sophie -
JOSEPH KOSUTH is a conceptual artist, drawing concepts from language, history, philosophy, semiotics (the study of signs & symbols) and a range of cultural references to create his art. He is strongly influenced by the philosophy of LUDWIG WITTGENSTEIN and the Russian SUPREMATIST artist KAZIMIR MALEVICH.
He's one smart cookie. I was a switchboard operator while attending his class and found the juxtaposition of art theory and practical necessity hilarious.
With love,
Mom
