To preserve Nature's chiefest boon, that is freedom, I can find means of offence and defence, when it is assailed by ambitious tyrants, and first I will speak of the situation of the walls, and also I shall show how communities can maintain their good and just Lords.
Leonardo da Vinci
-
Fire destroys all sophistry, that is deceit; and maintains truth alone, that is gold.

There will be many which will increase in their destruction.
Leonardo da Vinci

The spirit has no voice, because where there is a voice there is a body, and where there is a body space is occupied, and this prevents the eye from seeing what is placed behind that space; hence the surrounding air is filled by the body, that is by its image.
Leonardo da Vinci
-
Man has much power of discourse which for the most part is vain and false; animals have but little, but it is useful and true, and a small truth is better than a great lie.
Leonardo da Vinci
-
Every body in light and shade fills the surrounding air with infinite images of itself; and these, by infinite pyramids diffused in the air, represent this body throughout space and on every side.
Leonardo da Vinci

Why does the eye see a thing more clearly in dreams than with the imagination being awake?

I obey Thee Lord, first for the love I ought, in all reason to bear Thee; secondly for that Thou canst shorten or prolong the lives of men.
Leonardo da Vinci
-
The earth is not in the centre of the Sun's orbit nor at the centre of the universe, but in the centre of its companion elements, and united with them. And any one standing on the moon, when it and the sun are both beneath us, would see this our earth and the element of water upon it just as we see the moon, and the earth would light it as it lights us.
Leonardo da Vinci
-
Many will there be who will give up work and labour and poverty of life and goods, and will go to live among wealth in splendid buildings, declaring that this is the way to make themselves acceptable to God.
Leonardo da Vinci
-
I give the degrees of things seen by the eye as the musician does of the sounds heard by the ear.
Leonardo da Vinci
-
All objects transmit their image to the eye in pyramids, and the nearer to the eye these pyramids are intersected the smaller will the image appear of the objects which cause them.
Leonardo da Vinci
