Body and matter are here the same thing although there is hardly any such thing as synonym in the most rigorous sense of the word. There have been persons who by this word “body” have understood “spirit” also. They have said spirit originally signifies breath; only a body can breathe, therefore body and spirit may, after all, be the same thing. In this sense La Fontaine said to the celebrated Duke de la Rochefoucauld: “J’entens les esprits corps et pétris de matière.” In the same sense he says to Madame Sablière:

Je subtiliserais un morceau de matière,

Quintessence d’atome, extrait de la lumière,

Je ne sais quoi plus vif et plus subtil encor . . . .

No one thought of harassing good Monsieur La Fontaine, or bringing him to trial for his expressions. Were a poor philosopher, or even a poet, to say as much nowadays, how many would there be to fall on him! How many scribblers to sell their extracts for sixpence! How many knaves, for the sole purpose of making mischief, to cry philosopher! peripatetic! disciple of Gassendi! pupil of Locke, and the primitive fathers! damnable!

As we know not what a spirit is, so also we are ignorant of what a body is; we see various properties, but what is the subject in which those properties reside? “There is nothing but body,” said Democritus and Epicurus; “there is no such thing as body,” said the disciples of Zeno, of Elia.

Berkeley, bishop of Cloyne, is the last who, by a hundred captious sophisms, has pretended to prove that bodies do not exist. They have, says he, neither color, nor smell, nor heat; all these modalities are in your sensations, not in the objects. He might have spared himself the trouble of proving this truth for it was already sufficiently known. But thence he passed to extent and solidity, which are essential to body, and thinks he proves that there is no extent in a piece of green cloth because the cloth is not in reality green, the sensation of green being in ourselves only, therefore the sensation of extent is likewise in ourselves only. Having thus destroyed extent he concludes that solidity, which is attached to it, falls of itself, and therefore that there is nothing in the world but our ideas. So that, according to this doctor, ten thousand men killed by ten thousand cannon shots are in reality nothing more than ten thousand apprehensions of our understanding, and when a female becomes pregnant it is only one idea lodged in another idea from which a third idea will be produced.

Surely, the bishop of Cloyne might have saved himself from falling into this excessive absurdity. He thinks he shows that there is no extent because a body has appeared to him four times as large through a glass as to his naked eye, and four times as small through another glass. Hence he concludes, that, since a body cannot be at the same time four feet, sixteen feet, and but one foot in extent, there is no extent, therefore there is nothing. He had only to take any measure and say: of whatever extent this body may appear to me to be, it extends to so many of these measures.

He might very easily see that............
