Quotes from the same author

The extreme limit of wisdom, that's what the public calls madness.
 Jean Cocteau
I shall never forget what I saw at the Museum of Modern Art: in a spotless schoolroom, fifty little girls painting away at tables covered with brushes, pots, tubes, bowls, staring into space and sticking out their tongues like the clever animals that ring a bell, tongues lolling and eyes vague. Teachers supervise these young creators of abstract art and slap their wrists if what they paint represents something and dangerously inclines toward realism. The mothers - still at the Picasso stage - are not admitted.
 Jean Cocteau
I have never felt any connection with my family. There is—I must say simply—something in me that is not in my family. That was not visible in my father or mother. I do not know its origin.
 Jean Cocteau
Nothing is more intriguing than a still photograph in the middle of a motion picture... Just as an accident is a cry changed into silence and not a silence after a cry, photography is speed rendered motionless.
 Jean Cocteau
All good music resembles something. Good music stirs by its mysterious resemblance to the objects and feelings which motivated it.
 Jean Cocteau
