arithmeticians teach to add and subtract in numbers; so the geometricians teach the same in lines, figures, solid and superficial, angles, proportions, times, degrees of swiftness, force, power, and the like; the logicians teach the same in consequences of words; adding together two names to make an affirmation, and two affirmations to make a syllogism; and many syllogisms to make a demonstration; and from the sum, or conclusion of a syllogism, they subtract one proposition to find the other. Writers of politics add together pactions to find men's duties; and lawyers, laws and facts, to find what is right and wrong in the actions of private men. In sum, in what matter soever there is place for addition and subtraction, there also is place for reason; and where these have no place, there reason has nothing at all to do.

Out of all which we may define, that is to say determine, what that is, which is meant by this word reason, when we reckon it amongst the faculties of the mind. For REASON, in this sense, is nothing but reckoning, that is adding and subtracting, of the consequences of general names agreed upon for the marking and signifying of our thoughts; I say marking them when we reckon by ourselves, and signifying, when we demonstrate or approve our reckonings to other men.

And, as in arithmetic, unpractised men must, and professors themselves may often, err, and cast up false; so also in any other subject of reasoning, he ablest, most attentive, and most practised men

deceive themselves, and infer false conclus; not but that reason itself is always right son, as well as arithmetic is a certain and infal

lible art but no one man's reason, nor the reason of any one number of men, makes the certainty; no more than an account is therefore well cast up, because a great many men have unanimously approved it. And therefore, as when there is a controversy in an account, the parties must by their own accord, set up, for right reason, the reason of some arbitrator, or judge, to whose sentence they will both stand, or their controversy must either come to blows, or be undecided, for want of a right reason constituted by nature; so is it also in all debates of what kind soever. And when men that think themselves wiser than all others, clamour and demand right reason for judge, yet seek no more, but that things should be determined, by no other men's reason but their own, it is as intolerable in the society of men, as it is in play after trump is turned, to use for trump on every occasion, that suite whereof they have most in their hand. For they do nothing else, that will have every of their passions, as it comes to bear sway in them, to be taken for right reason, and that in their own controversies bewraying their want of right reason, by the claim they lay to it.

The use and end of reason, is not the finding of The use of the sum and truth of one, or a few consequences, remote from the first definitions, and settled significations of names, but to begin at these, and proceed from one consequence to another. For there can be no certainty of the last conclusion, without a certainty of all those affirmations and negations, on which it was grounded and inferred. As when a master of a family, in taking an account, casteth up the sums of all the bills of expense into one sum,

Of error and absurdity.

and not regarding how each bill is summed up, by those that give them in account; nor what it is he pays for; he advantages himself no more, than if he allowed the account in gross, trusting to every of the accountants' skill and honesty : so also in reasoning of all other things, he that takes up conclusions on the trust of authors, and doth not fetch them from the first items in every reckoning, which are the significations of names settled by definitions, loses his labour; and does not know anything, but only believeth.

When a man reckons without the use of words, which may be done in particular things, as when upon the sight of any one thing, we conjecture what was likely to have preceded, or is likely to follow upon it; if that which he thought likely to follow, follows not, or that which he thought likely to have preceded it, hath not preceded it, this is called error; to which even the most prudent men are subject. But when we reason in words of general signification, and fall upon a general inference which is false, though it be commonly called error, it is indeed an absurdity, or senseless speech. For error is but a deception, in presuming that somewhat is past, or to come; of which, though it were not past, or not to come, yet there was no impossibility discoverable. But when we make a general assertion, unless it be a true one, the possibility of it is inconceivable. And words whereby we conceive nothing but the sound, are those we call absurd, insignificant, and nonsense. And therefore if a man should talk to me of a round quadrangle; or, accidents of bread in cheese; or, immaterial substances; or of a free subject; a free will; or

5.

any free, but free from being hindered by opposi- PART I. tion, I should not say he were in an error, but that his words were without meaning, that is to say, absurd.

I have said before, in the second chapter, that a man did excel all other animals in this faculty, that when he conceived any thing whatsoever, he was apt to inquire the consequences of it, and what effects he could do with it. And now I add this other degree of the same excellence, that he can by words reduce the consequences he finds to general rules, called theorems, or aphorisms; that is, he can reason, or reckon, not only in number, but in all other things, whereof one may be added unto, or subtracted from another.

But this privilege is allayed by another; and that is, by the privilege of absurdity; to which no living creature is subject, but man only. And of men, those are of all most subject to it, that profess philosophy. For it is most true that Cicero saith of them somewhere; that there can be nothing so absurd, but may be found in the books of philosophers. And the reason is manifest. For there is not one of them that begins his ratiocination from the definitions, or explications of the names they are to use; which is a method that hath been used only in geometry; whose conclusions have thereby been made indisputable.

I. The first cause of absurd conclusions I ascribe Causes of absurdity. to the want of method; in that they begin not their ratiocination from definitions; that is, from settled significations of their words: as if they could cast account, without knowing the value of the numeral words, one, two, and three.

PART I.

And whereas all bodies enter into account upon 5. divers considerations, which I have mentioned in Causes of the precedent chapter; these considerations being diversely named, divers absurdities proceed from the confusion, and unfit connexion of their names into assertions. And therefore,

absurdity.

II. The second cause of absurd assertions, I asscribe to the giving of names of bodies to accidents; or of accidents to bodies; as they do, that say, faith is infused, or inspired; when nothing can be poured, or breathed into anything, but body; and that, extension is body; that phantasms are spirits, &c.

III. The third I ascribe to the giving of the names of the accidents of bodies without us, to the accidents of our own bodies; as they do that say, the colour is in the body; the sound is in the air, &c.

IV. The fourth, to the giving of the names of bodies to names, or speeches; as they do that say, that there be things universal; that a living creature is genus, or a general thing, &c.

v. The fifth, to the giving of the names of accidents to names and speeches; as they do that say, the nature of a thing is its definition; a man's command is his will; and the like.

VI. The sixth, to the use of metaphors, tropes, and other rhetorical figures, instead of words proper. For though it be lawful to say, for example, in common speech, the way goeth, or leadeth hither, or thither; the proverb says this or that, whereas ways cannot go, nor proverbs speak; yet in reckoning, and seeking of truth, such speeches are not to be admitted.

VII. The seventh, to names that signify nothing;
