"Because," say some, "you have believed from childhood that a box was empty when you saw nothing in it, you have therefore believed the possibility of a vacuum. This is an illusion of your senses, strengthened by custom, which science must correct." "Because," say others, "you were taught at school that there is no such thing as a vacuum, your common sense, which clearly comprehended the matter before, is corrupted, and you must correct this false impression by returning to your primitive nature." Which has deceived you, your senses or your education?
Diseases are another source of error. They impair our judgment and our senses, and if the more violent produce a sensible change, I do not doubt that slighter ailments produce each its proportionate impression.
Our own interest is again a wonderful instrument for putting out our eyes in a pleasant way. The man of greatest probity can not be judge in his own cause; I know some who that they may not fall into this self love are, out of opposition, thoroughly unjust. The certain way of ruining a just cause has been to get it recommended to these men by their near relatives.

If he had only reason without passions....
If he had only passions without reason....
But having both he must have continual strife, since he cannot be at peace with one unless he be at war with the other. Hence he is always divided against and contrary to himself.
The habit of seeing kings accompanied by guards, drums, officers and all those things which mechanically incline man to respect and terror, causes their countenance, when now and then seen alone, and without these accompaniments, to impress respect and terror on their subjects, because our thought cannot separate their personality from those surroundings with which it is ordinarily joined. And the world which does not know that the effect arises from habit, believes that it arises from natural force, and hence come such expressions as: "The character of Divinity is imprinted on his countenance," etc.
The power of kings is based both on the reason and the folly of the people, and mainly on their folly. The greatest and most important matter in the world has weakness for its foundation, and this foundation is admirably sure, for there is nothing more sure than this, that the people will be weak. What is founded on sound reason is very ill founded, as the value of wisdom.
