Leviathan. Thomas Hobbes

without reckoning anew from the beginning; in which lyes the foundation of their errours. From whence it happens, that they which trust to books, do as they that cast up many little summs into a greater, without considering whether those little summes were rightly cast up or not; and at last finding the errour visible, and not mistrusting their first grounds, know not which way to cleere themselves; but spend time in fluttering over their bookes; as birds that entring by the chimney, and finding themselves inclosed in a chamber, flitter at the false light of a glasse window, for want of wit to consider which way they came in. So that in the right Definition of Names, lyes the first use of Speech; which is the Acquisition of Science: And in wrong, or no Definitions' lyes the first abuse; from which proceed all false and senslesse Tenets; which make those men that take their instruction from the authority of books, and not from their own meditation, to be as much below the condition of ignorant men, as men endued with true Science are above it. For between true Science, and erroneous Doctrines, Ignorance is in the middle. Naturall sense and imagination, are not subject to absurdity. Nature it selfe cannot erre: and as men abound in copiousnesse of language; so they become more wise, or more mad than ordinary. Nor is it possible without Letters for any man to become either excellently wise, or (unless his memory be hurt by disease, or ill constitution of organs) excellently foolish. For words are wise mens counters, they do but reckon by them: but they are the mony of fooles, that value them by the authority of an Aristotle, a Cicero, or a Thomas, or any other Doctor whatsoever, if but a man.

      Subject To Names

      Subject To Names, is whatsoever can enter into, or be considered in an account; and be added one to another to make a summe; or substracted one from another, and leave a remainder. The Latines called Accounts of mony Rationes, and accounting, Ratiocinatio: and that which we in bills or books of account call Items, they called Nomina; that is, Names: and thence it seems to proceed, that they extended the word Ratio, to the faculty of Reckoning in all other things. The Greeks have but one word Logos, for both Speech and Reason; not that they thought there was no Speech without Reason; but no Reasoning without Speech: And the act of reasoning they called syllogisme; which signifieth summing up of the consequences of one saying to another. And because the same things may enter into account for divers accidents; their names are (to shew that diversity) diversly wrested, and diversified. This diversity of names may be reduced to foure generall heads.

      First, a thing may enter into account for Matter, or Body; as Living, Sensible, Rationall, Hot, Cold, Moved, Quiet; with all which names the word Matter, or Body is understood; all such, being names of Matter.

      Secondly, it may enter into account, or be considered, for some accident or quality, which we conceive to be in it; as for Being Moved, for Being So Long, for Being Hot, &c; and then, of the name of the thing it selfe, by a little change or wresting, wee make a name for that accident, which we consider; and for Living put into account Life; for Moved, Motion; for Hot, Heat; for Long, Length, and the like. And all such Names, are the names of the accidents and properties, by which one Matter, and Body is distinguished from another. These are called Names Abstract; Because Severed (not from Matter, but) from the account of Matter.

      Thirdly, we bring into account, the Properties of our own bodies, whereby we make such distinction: as when any thing is Seen by us, we reckon not the thing it selfe; but the Sight, the Colour, the Idea of it in the fancy: and when any thing is Heard, wee reckon it not; but the Hearing, or Sound onely, which is our fancy or conception of it by the Eare: and such are names of fancies.

      Fourthly, we bring into account, consider, and give names, to Names themselves, and to Speeches: For, Generall, Universall, Speciall, Oequivocall, are names of Names. And Affirmation, Interrogation, Commandement, Narration, Syllogisme, Sermon, Oration, and many other such, are names of Speeches.

      Use Of Names Positive

      And this is all the variety of Names Positive; which are put to mark somewhat which is in Nature, or may be feigned by the mind of man, as Bodies that are, or may be conceived to be; or of bodies, the Properties that are, or may be feigned to be; or Words and Speech.

      Negative Names With Their Uses

      There be also other Names, called Negative; which are notes to signifie that a word is not the name of the thing in question; as these words Nothing, No Man, Infinite, Indocible, Three Want Foure, and the like; which are nevertheless of use in reckoning, or in correcting of reckoning; and call to mind our past cogitations, though they be not names of any thing; because they make us refuse to admit of Names not rightly used.

      Words Insignificant

      All other names, are but insignificant sounds; and those of two sorts. One, when they are new, and yet their meaning not explained by Definition; whereof there have been aboundance coyned by Schoole-men, and pusled Philosophers.

      Another, when men make a name of two Names, whose significations are contradictory and inconsistent; as this name, an Incorporeall Body, or (which is all one) an Incorporeall Substance, and a great number more. For whensoever any affirmation is false, the two names of which it is composed, put together and made one, signifie nothing at all. For example if it be a false affirmation to say A Quadrangle Is Round, the word Round Quadrangle signifies nothing; but is a meere sound. So likewise if it be false, to say that vertue can be powred, or blown up and down; the words In-powred Vertue, In-blown Vertue, are as absurd and insignificant, as a Round Quadrangle. And therefore you shall hardly meet with a senselesse and insignificant word, that is not made up of some Latin or Greek names. A Frenchman seldome hears our Saviour called by the name of Parole, but by the name of Verbe often; yet Verbe and Parole differ no more, but that one is Latin, the other French.

      Understanding

      When a man upon the hearing of any Speech, hath those thoughts which the words of that Speech, and their connexion, were ordained and constituted to signifie; Then he is said to understand it; Understanding being nothing els, but conception caused by Speech. And therefore if Speech be peculiar to man (as for ought I know it is,) then is Understanding peculiar to him also. And therefore of absurd and false affirmations, in case they be universall, there can be no Understanding; though many think they understand, then, when they do but repeat the words softly, or con them in their mind.

      What kinds of Speeches signifie the Appetites, Aversions, and Passions of mans mind; and of their use and abuse, I shall speak when I have spoken of the Passions.

      Inconstant Names

      The names of such things as affect us, that is, which please, and displease us, because all men be not alike affected with the same thing, nor the same man at all times, are in the common discourses of men, of Inconstant signification. For seeing all names are imposed to signifie our conceptions; and all our affections are but conceptions; when we conceive the same things differently, we can hardly avoyd different naming of them. For though the nature of that we conceive, be the same; yet the diversity of our reception of it, in respect of different constitutions of body, and prejudices of opinion, gives everything a tincture of our different passions. And therefore in reasoning, a man bust take heed of words; which besides the signification of what we imagine of their nature, disposition, and interest of the speaker; such as are the names of Vertues, and Vices; For one man calleth Wisdome, what another calleth Feare; and one Cruelty, what another Justice; one Prodigality, what another Magnanimity; one Gravity, what another Stupidity, &c. And
