"Art is the queen of all sciences..." - Quote by Leonardo Da Vinci

“Oysters open completely when the moon is full; and when the crab sees one it throws a piece of stone or seaweed into it and the oyster cannot close again so that it serves the crab for meat. Such is the fate of him who opens his mouth too much and thereby puts himself at the mercy of the listener.”

“Although the poet has as wide a choice of subjects as the painter, his creations fail to afford as much satisfaction to mankind as do paintings... if the poet serves the understanding by way of the ear, the painter does so by the eye, which is the nobler sense.”

“Every now and then go away, have a little relaxation, for when you come back to your work your judgment will be surer.”

“While one should always study the method of a great artist, one should never imitate his manner. The manner of an artist is essentially individual, the method of an artist is absolutely universal. The first personality, which no one should copy.”

“All high beauty has a moral element in it.”

“If you're a guest [at my $113 million house], you'll be able to call up on screens throughout the house almost any image you like - presidential portraits, reproductions of High Renaissance paintings, pictures of sunsets, airplanes, skiers in the Andes, a rare French stamp, the Beatles in 1965.”

“I've always been amazed by Da Vinci, because he worked out science on his own. He would work by drawing things and writing down his ideas. Of course, he designed all sorts of flying machines way before you could actually build something like that.”

“Sometimes people feel mind is merely the - in some animal, the energy or something from the brain. Now there are little sort of curiosities or I think doubt sometimes a sheer sort of mental attitude, some change in our brain. So these fields, now scientists are showing some interest.”

“I am not a positivist. Positivism states that what cannot be observed does not exist. This conception is scientifically indefensible, for it is impossible to make valid affirmations of what people 'can' or 'cannot' observe. One would have to say 'only what we observe exists,' which is obviously false.”
