I regard the theatre as the greatest of all art forms, the most immediate way in which a human being can share with another the sense of what it is to be a human being.

It is through art, and through art only, that we can realise our perfection.

All art is quite useless.

The moment you think you understand a great work of art, it's dead for you.

It is only an auctioneer who can equally and impartially admire all schools of art.
