«Fine art, that exists for itself alone, is art in a final state of impotence. If nobody, including the artist, acknowledges art as a means of knowing the world, then art is relegated to a kind of rumpus room of the mind and the irresponsibility of the artist and the irrelevance of art to actual living becomes part and parcel of the practice of art.»

«I hope that some day the practice of producing cowpox in human beings will spread over the world - when that day comes, there will be no more smallpox»

«Christianity: an interesting concept; however, no one keeps true to the practice.»

«If we can, when we have established individual discipline, arrange the children, sending each one to his own place, in order, trying to make them understand the idea that thus placed they look well, and that it is a good thing to be thus placed in order, that it is a good and pleasing arrangement in the room, this ordered and tranquil adjustment of theirs -- then their remaining in their places, quiet and silent, is the result of a species of lesson, not an imposition. To make them understand the idea, without calling their attention too forcibly to the practice, to have them assimilate a principle of collective order -- that is the important thing.»

«God forbid that any book should be banned. The practice is as indefensible as infanticide.»

«Abused as we abuse it at present, dramatic art is in no sense cathartic; it is merely a form of emotional masturbation. It is the rarest thing to find a player who has not had his character affected for the worse by the practice of his profession. Nobody can make a habit of self-exhibition, nobody can exploit his personality for the sake of exercising a kind of hypnotic power over others, and remain untouched by the process.»

«I have noticed that doctors who fail in the practice of medicine have a tendency to seek one another's company and aid in consultation. A doctor who cannot take out your appendix properly will recommend you to a doctor who will be unable to remove your tonsils with success.»

«I believe in the practice and philosophy of what we have agreed to call magic, and what I must call the evocation of spirits, though I do not know what they are, in the power of creating magic illusions in the visions of truth in the depths of the minds when the eyes are closed.»
