Leonardo da Vinci

Leonardo da Vinci
The art of procreation and the members employed therein are so repulsive, that if it were not for the beauty of the faces and the adornments of the actors and the pent-up impulse, nature would lose the human species.
Leonardo da Vinci
O speculators about perpetual motion, how many vain chimeras have you created in the like quest? Go and take your place with the seekers after gold.
Leonardo da Vinci

Leonardo da Vinci
The cat is nature's masterpiece.
Leonardo da Vinci
He who walks straight rarely falls.
Leonardo da Vinci
Fire is to represent truth because it destroys all sophistry and lies and the mask is for lying and falsehood which conceal truth.
Leonardo da Vinci
Experience does not err. Only your judgments err by expecting from her what is not in her power.
Leonardo da Vinci
It is useful to constantly observe, note, and consider.
Leonardo da Vinci
O mighty and once living instrument of formative nature. Incapable of availing thyself of thy vast strength thou hast to abandon a life of stillness and to obey the law which God and time gave to procreative nature.
Leonardo da Vinci
Perspective is a most subtle discovery in mathematical studies, for by means of lines it causes to appear distant that which is near, and large that which is small.
Leonardo da Vinci
I am still hopeful. A falcon, Time. But the coincidence is probably accidental.
Leonardo da Vinci
In time and with water, everything changes.
Leonardo da Vinci
life without love, is no life at all
Leonardo da Vinci
To be a winner you must want to win but must know of the chance of losing and must not fear of it.
Leonardo da Vinci
