Iron rusts from disuse; water loses its purity from stagnation... even so does inaction sap the vigor of the mind.

He who wishes to be rich in a day will be hanged in a year.

Human subtlety will never devise an invention more beautiful, more simple or more direct than does nature because in her inventions nothing is lacking, and nothing is superfluous.

From Leonardo da Vinci

The painter who draws merely by practice and by eye, without any reason, is like a mirror which copies every thing placed in front of it without being conscious of their existence.

From Leonardo da Vinci

It seems that it had been destined before that I should occupy myself so thoroughly with the vulture, for it comes to my mind as a very early memory, when I was still in the cradle, a vulture came down to me, he opened my mouth with his tail and struck me a few times with his tail against my lips.

From Leonardo da Vinci

I have found that, in the composition of the human body as compared with the bodies of animals, the organs of sense are duller and coarser. Thus, it is composed of less ingenious instruments, and of spaces less capacious for receiving the faculties of sense.

From Leonardo da Vinci

Medicine is the restoration of discordant elements; sickness is the discord of the elements infused into the living body.

From Leonardo da Vinci

Many are they who have a taste and love for drawing, but no talent; and this will be discernible in boys who are not diligent and never finish their drawings with shading.

From Leonardo da Vinci

Man and animals are in reality vehicles and conduits of food, tombs of animals, hostels of Death, coverings that consume, deriving life by the death of others.

From Leonardo da Vinci

Weight, force and casual impulse, together with resistance, are the four external powers in which all the visible actions of mortals have their being and their end.
