Abuses Of Speech

To these Uses, there are also foure correspondent Abuses. First, when men register their thoughts wrong, by the inconstancy of the signification of their words; by which they register for their conceptions, that which they never conceived; and so deceive themselves. Secondly, when they use words metaphorically; that is, in other sense than that they are ordained for; and thereby deceive others. Thirdly, when by words they declare that to be their will, which is not. Fourthly, when they use them to grieve one another: for seeing nature hath armed living creatures, some with teeth, some with horns, and some with hands, to grieve an enemy, it is but an abuse of Speech, to grieve him with the tongue, unlesse it be one whom wee are obliged to govern; and then it is not to grieve, but to correct and amend.

Names Proper & Common Universall

it is called an Universall; there being nothing in the world Universall but Names; for the things named, are every one of them Individual and Singular.

But here wee must take notice, that by a Name is not alwayes understood, as in Grammar, one onely word; but sometimes by circumlocution many words together. For all these words, Hee That In His Actions Observeth The Lawes Of His Country, make but one Name, equivalent to this one word, Just.

And it seems, there was a time when those names of number were not in use; and men were fayn to apply their fingers of one or both hands, to those things they desired to keep account of; and that thence it proceeded, that now our numerall words are but ten, in any Nation, and in some but five, and then they begin again.

For True and False are attributes of Speech, not of

things. And where Speech in not, there is neither Truth nor Falshood. Errour there may be, as when wee expect that which shall not be; or suspect what has not been: but in neither case can a man be charged with Untruth.

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.

For words are wise mens counters, they do but

words are wise men's counters

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 T...

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:

Use Of Names Positive

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 Insign...

All other names, are but insignificant sounds; and those of two sorts. One, when they are new...

explained by Definition; whereof there have been aboundance coyned by Schoole-men,...

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 w...

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, b...

Inconstant Names

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 therefore such names can never be true grounds of any ratiocination. No more can Metaphors, and Tropes of speech: but these are less dangerous, because they profess their inconstancy; which the other do not.

CHAPTER V. OF REASON, AND SCIENCE.

Reason Wha...

Reason Defined

Reckoning (that is, Adding and Substracting) of the Consequences of generall names agreed upon, for the Marking and Signifying of our thoughts; I say Marking them, when we reckon by our selves; and Signifying, when we demonstrate, or approve our reckonings to other men.

Right Reason Where

But no one mans Reason, nor the Reason of any one number of men, makes the certaintie; no more than an account is therefore well cast up, because a great many men have unanimously approved it. And therfore, 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 controversie must either come to blowes, or be undecided,

for want of a right Reason constituted by Nature; so is it also in all debates of what kind soever:

For they do nothing els, 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 claym they lay to it.

The Use Of Reason

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 any thing; but onely beleeveth.

Of Error And Absurdity

But when we make

a generall assertion, unlesse it be a true one, the possibility of it is unconceivable. And words whereby we conceive nothing but the sound, are those we call Absurd, insignificant, and Non-sense. 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 any Free, but free from being hindred by opposition, I should not say he were in an Errour; but that his words were without meaning; that is to say, Absurd.

free subject and free will are absurd

now I adde this other degree of the same excellence, that he can by words reduce the consequences he findes to generall Rules, called Theoremes, or Aphorismes; that is, he can Reason, or reckon, not onely in number; but in all other things, whereof one may be added unto, or substracted from another.

But this priviledge, is allayed by another; and that is, by the priviledge of Absurdity; to which no living creature is subject, but man onely. And of men, those are of all most subject to it, that professe Philosophy. For it is most true that Cicero sayth 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 onely...

Causes Of Abs...

The first cause of Absurd conclusions I ascribe 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 k...

The second cause of Absurd assertions, I ascribe 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 Powred, or Breathed into any thing, but body; and that, Extension is

Body; that Phantasmes are Spirits, &c.

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...

The fourth, to the giving of the names of Bodies, to Names, or Speeches; as they do that say, that There Be Things Universall; that A Living Cre...

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 In Its Definition; A...

sixth, to the use of Metaphors, Tropes, and other Rhetoricall figures, in stead of words proper. For though it be lawfull to say, (for example) in common speech, The Way Goeth, Or Leadeth Hither, Or Thither, The Proverb Sayes This Or That (whereas wayes cannot go, nor Proverbs speak;) y...

metaphors etc.

The seventh, to names that signifie nothing; but are taken up, and learned by rote from the Schooles, as Hypostatical, Transubstantiate, Consubstanti...
