Author Quotes

All objects project their whole image and likeness, diffused and mingled in the whole of the atmosphere, opposite to themselves. The image of every point of the bodily surface, exists in every part of the atmosphere. All the images of the objects are in every part of the atmosphere.

The air is filled with endless images of the objects distributed in it; and all are represented in all, and all in one, and all in each, whence it happens that if two mirrors are placed in such a manner as to face each other exactly, the first will be reflected in the second and the second in the first. The first being reflected in the second takes to it the image of itself with all the images represented in it, among which is the image of the second mirror, and so, image within image, they go on to infinity in such a manner as that each mirror has within it a mirror, each smaller than the last and one inside the other. Thus, by this example, it is clearly proved that every object sends its image to every spot whence the object itself can be seen; and the converse: That the same object may receive in itself all the images of the objects that are in front of it.

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.

The point, being indivisible, occupies no space. That which occupies no space is nothing. The limiting surface of one thing is the beginning of another.

Nothing is that which fills no space. If one single point placed in a circle may be the starting point of an infinite number of lines, and the termination of an infinite number of lines, there must be an infinite number of points separable from this point, and these when reunited become one again; whence it follows that the part may be equal to the whole.

The smallest natural point is larger than all mathematical points, and this is proved because the natural point has continuity, and any thing that is continuous is infinitely divisible; but the mathematical point is indivisible because it has no size.

Necessity is the mistress and guardian of Nature.

The supreme misfortune is when theory outstrips performance.

The organ of perception acts more readily than judgment.

An average human looks without seeing, listens without hearing, touches without feeling, eats without tasting, moves without physical awareness, inhales without awareness of odour or fragrance, and talks without thinking.

Make your work to be in keeping with your purpose.

The acquisition of knowledge is always of use to the intellect, because it may thus drive out useless things and retain the good. For nothing can be loved or hated unless it is first known.

Life without love, is no life at all.

Water is the driving force in nature.

The time will come when men such as I will look upon the murder of animals as they now look on the murder of men.

Obstacles cannot crush me; every obstacle yields to stern resolve.

Our life is made by the death of others.

He who thinks little errs much.

The knowledge of all things is possible.

Study without desire spoils the memory, and it retains nothing that it takes in.

You do ill if you praise, but worse if you censure, what you do not understand.

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

While I thought that I was learning how to live, I have been learning how to die.

Where there is shouting, there is no true knowledge.

The truth of things is the chief nutriment of superior intellects.
