"The greatest geniuses sometimes accomplish more when..." - Quote by Leonardo Da Vinci

“Although nature commences with reason and ends in experience it is necessary for us to do the opposite, that is to commence with experience and from this to proceed to investigate the reason.”

“Demetrius was wont to say that there was no difference between the words and speech of the unskilled and ignorant and the sounds and rumblings caused by the stomach being full of superfluous wind. This he said, not without reason, for, as he held, it did not in the least matter from what part of them the voice emanated, whether from the lower parts or the mouth, since the one and the other were of equal worth and importance.”

“I think it is no small attraction in a painter to be able to give a pleasing air to his figures, and whoever is not naturally possessed of this grace may acquire it by study, as opportunity offers in the following manner: be on the watch to take good parts of many beautiful faces of which the beautiful parts are established by general repute rather than by your own judgement, for you may deceive yourself by selecting faces that resemble your own, since it often seems that such similarities please us; ... so therefore choose the beautiful ones as I tell you and fix them in your mind.”

“Great geniuses have the shortest biographies.”

“Genius is intellect constructive.”

“Sex energy is the creative energy of all creative geniuses.”

“A genius is the man in whom you are least likely to find the power of attending to anything insipid or distasteful in itself. He breaks his engagements, leaves his letters unanswered, neglects his family duties incorrigibly, because he is powerless to turn his attention down and back from those more interesting trains of imagery with which his genius constantly occupies his mind.”

“Almost any biographer, if he respects facts, can give us much more than another fact to add to our collection. He can give us the creative fact; the fertile fact; the fact that suggests and engenders.”

“Every picture has its own demands, and every picture stimulates something within you to tell it a certain way. I don't know what that is; I don't think too much about that.”
