To such an extent does nature delight and abound in variety that among her trees there is not one plant to be found which is exactly like another.
The good painter has two principal things to depict: man and the purpose of his mind. The first is easy, the second is difficult, since he must do it by the gestures and movements of the limbs, and this is to be learnt from the dumb, who more than all other men excel in it.
The painter's work will be of little merit if he takes the painting of others as his standard, but if he studies from nature he will produce good fruits.
Oh! marvellous, O stupendous Necessity -- by thy laws thou dost compel every effect to be the direct result of its cause, by the shortest path. These are miracles.
Although human ingenuity may devise various inventions which, by the help of various instruments, answer to one and the same purpose, yet will it never discover any inventions more beautiful, more simple or more practical than those of nature.
For once you have tasted flight, you will forever walk the earth with your eyes turned skyward, for there you have been, and there you will always long to return.
Supreme happiness will be the greatest cause of misery, and the perfection of wisdom the occasion of folly.
Learning acquired in youth arrests the evil of old age; and if you understand that old age has wisdom for its food, you will so conduct yourself in youth that your old age will not lack for nourishment.
A deaf and dumb person who sees two men in conversation may nevertheless understand from the attitudes and gestures of the speakers, how well their discussion is getting along.

Anyone who conducts an argument by appealing to authority is not using his intelligence, he is just using his memory.
Mechanics is the paradise of the mathematical sciences because by means of it, one comes to the fruits of mathematics.
What is called nothingness is to be found only in time and in speech. In time it stands between the past and future and has no existence in the present; and thus in speech it is one of the things of which we say: They are not, or they are impossible.
O admirable necessity! O powerful action! What mind can penetrate your nature? What language can express this marvel? None, to be sure. This is where human discourse turns toward the contemplation of the divine.
Whoever despises the high wisdom of mathematics nourishes himself on delusion and will never still the sophistic sciences whose only product is an eternal uproar.
For once you have tasted flight you will walk the Earth with your eyes turned skywards, for there you have been and there you will long to return.
The men of experiment are like the ant; they only collect and use. But the bee...gathers its materials from the flowers of the garden and of the field, but transforms and digests it by a power of its own.
The instant the atmosphere is illuminated it will be filled with an infinite number of images which are produced by the various bodies and colours assembled in it. And the eye is the target, a lodestone, of these images.
Do not imitate one another's style. If you do, so far as your art is concerned you will be called a grandson, rather than the son of Nature.
The mind of a painter should be like a mirror which is filled with as many images as there are things placed before him.

Appetite is the support of life
Fear or timidity is the prolongation of life, and

To discover the soul living in somebody's body, we watch the surrounding of the body, and if it's messy and disordered, so is the soul.
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.
Painting embraces and contains within itself all the things which nature produces or which results from the fortuitous actions of men... he is but a poor master who makes only a single figure well.

Make your faces so that they do not all have the same expression, as one sees with most painters, but give them different expression, according to age, complexion, and good or bad character.
No human investigation can be called real science if it cannot be demonstrated mathematically.
No human investigation can be called real knowledge if it does not pass through mathematical demonstrations; and if you say that the kinds of knowledge that begin and end in the mind have any value as truth, this cannot be conceded, but rather must be denied for many reasons, and first of all because in such mental discussions there is no experimentation, without which nothing provides certainty of itself.
Whatever you think matters -- doesn't. Follow this rule, and you will add decades to your life. Rodger Rosenblatt As a well spent day brings happy sleep, so life well used brings happy death.

The young man should first learn perspective, then the proportions of objects. Next, copy work after the hand of a good master, to gain the habit of drawing parts of the body well; and then to work from nature, to confirm the lessons learned.
Things severed shall be united and shall acquire of themselves such virtue that they shall restore to men their lost memory: -- That is the papyrus sheets, which are formed out of several strips and preserve the memory of the thoughts and deeds of men.
Every now and then go away, have a little relaxation, for when you come back to your work your judgment will be surer.
An artist who lacks the power of self-criticism accomplishes but little. It is good if your work stands higher than your own opinion of it; bad if it is on the same level. But it is a great disaster if your work stands lower than your judgment of it.

How the various circles of water form around the spot which has been struck by a stone and why a bird sustains itself in the air. These questions and other strange phenomena engaged my thought throughout my life.
If you put on more garments, the cold cannot reach you. Similarly, increase your patience and concentration and even great injuries cannot vex your mind.

It is ordained that to the ambitious, who derive no satisfaction from the gifts of life and the beauty of the world, life shall be a cause of suffering, and they shall possess neither the profit nor the beauty of the world.
Experience, the interpreter between creative nature and the human race, teaches the action of nature among mortals: how under the constraint of necessity she cannot act otherwise than as reason, who steers her helm, teaches her to act.

The mole has very small eyes and it always lives under ground; and it lives as long as it is in the dark but when it comes into the light it dies immediately, because it becomes known; -- and so it is with lies.
In fact, whatever exists in the universe, in essence, in appearance, in the imagination, the painter has first in his mind and then in his hands ... it lies in his power to create them.
Men of lofty genius sometimes accomplish the most when they work least, for their minds are occupied with their ideas and the perfection of their conceptions, to which they afterwards give form.

The vivacity and brightness of colors in a landscape will never bear any comparison with a landscape in nature when it is illumined by the sun, unless the painting is placed in such a position that it will receive the same light from the sun as does the landscape.
Look at light and admire its beauty. Close your eyes, and then look again: what you saw is no longer there; and what you will see later is not yet.
