Leonardo era definitivamente un genio. Como tal, usó su intelecto para vivir en sinfonía con la vida y escribir sobre muchas cosas que su mente traía de vuelta a nuestra realidad.

Men who desire nothing but material riches and are absolutely devoid of that of wisdom, which is the food and the only true riches of the mind. For so much more worthy as the soul is than the body, so much more noble are the possessions of the soul than those of the body.

— Leonardo Da Vinci.

Nothing is that which fills no space.

— Leonardo Da Vinci.

Every object as sit becomes more remote loses first those parts which are smallest.

— Leonardo Da Vinci.

The nature of the outline. The boundaries of bodies are the last of all things. The proposition is proved to be true, because the boundary of a thing is a surface, which is not part of the body contained within that surface; nor is it part of the air surrounding that body, but is the medium interposed between the air and the body, as is proved in its place. But the lateral boundaries of these bodies is the line forming the boundary of the surface, which line is of invisible thickness. Wherefore O Painter! do not surround your bodies with lines, and above all when representing object smaller than nature; for not only will their external outlines become indistinct, but their parts will be invisible from distance.

— Leonardo Da Vinci.

Every visible body, in so far as it affects the eye, includes three attributes, that is to say: mass, form and colour; and the mass is recognizable at a greater distance from the place of its actual existence than either colour or form. Again, colour is discernible at a greater distance than form, but this law does not apply to luminous bodies.

— Leonardo Da Vinci.

No white or black is transparent.

— Leonardo Da Vinci.

Il bianco non e colore ma e inpotentia ricettiva d'ogni colore. (White is not a colour, but the neutral recipient of every color.)

— Leonardo Da Vinci.

Hence, O Painter! when you represent mountains, see that from hill to hill the bases are paler than the summits, and in proportion as they recede beyond each other make the bases paler than the summits while, the higher they are the more you must show of their true form and colour.

— Leonardo Da Vinci.

Monboso, a peak of the Alps which divide France from Italy. The base of this mountain gives birth to the four rivers which flow in four different directions through the whole of Europe. And no mountain has its base at so great a height as this, which lifts itself almost above the clouds; and snow seldom falls there, but only hail in the summer, when the clouds are highest. And this hail lies [unmelted] there, so that if iy were not for the absorption of the rising and falling clouds, which does not happen twice in an age, an enormous mass of ice would be piled up there by the hail, and in the middle of July I found it very considerable.

— Leonardo Da Vinci.

Small rooms or dwelling discipline the mind, large ones weaken it.

— Leonardo Da Vinci.

If poetry deals with moral philosophy, painting deals with natural philosophy.

— Leonardo Da Vinci.

Our life is made by death of others. In dead matter insensible life remains, which, reunited to the stomachs of the living being, resumes life, both sensual and intellectual.

— Leonardo Da Vinci.

To keep in health, this rule is wise: eat only when you want and relish food. Chew thoroughly that it may do you good. Have it well cooked, unspiced and undisguised. He who takes medicine is ill advised.

— Leonardo Da Vinci.

The soul can never be corrupted with the corruption of the body, but is in the body as it were the air which causes the sound of the organ, where when a pipe bursts, the wind would cease to have any good effect.

— Leonardo Da Vinci.

The senses are of the earth; Reason, stands apart in contemplation.

— Leonardo Da Vinci.

All our knowledge has its origin in our perceptions.

— Leonardo Da Vinci.

Wisdom is the daughter of experience.

— Leonardo Da Vinci.

Truth was the only daughter of Time.

— Leonardo Da Vinci.

Nothing can be loved or hated unless it is first known.

— Leonardo Da Vinci.

It is true that impatience, the mother of stupidity, praises brevity.

— Leonardo Da Vinci.
