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 What It Is

When a man Reasoneth, hee does nothing els but conceive a summe totall,
from Addition of parcels; or conceive a Remainder, from Substraction of
one summe from another: which (if it be done by Words,) is conceiving of
the consequence of the names of all the parts, to the name of the whole;
or from the names of the whole and one part, to the name of the other
part. And though in some things, (as in numbers,) besides Adding and
Substracting, men name other operations, as Multiplying and Dividing;
yet they are the same; for Multiplication, is but Addition together of
things equall; and Division, but Substracting of one thing, as often as
we can. These operations are not incident to Numbers onely, but to
all manner of things that can be added together, and taken one out of
another. For as Arithmeticians teach to adde and substract in Numbers;
so the Geometricians teach the same in Lines, Figures (solid and
superficiall,) Angles, Proportions, Times, degrees of Swiftnesse, 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 syllogisme; and Many syllogismes to make a
Demonstration; and from the Summe, or Conclusion of a syllogisme, they
substract one Proposition, to finde the other. Writers of Politiques,
adde together Pactions, to find mens Duties; and Lawyers, Lawes and
Facts, to find what is Right and Wrong in the actions of private men.
In summe, in what matter soever there is place for Addition and
Substraction, there also is place for Reason; and where these have no
place, there Reason has nothing at all to do.

Reason Defined

Out of all which we may define, (that is to say determine,) what that
is, which is meant by this word Reason, when wee reckon it amongst
the Faculties of the mind. For Reason, in this sense, is nothing but
Reckoning (that is, Adding and Substracting) of the Consequences of
generall names agreed upon, for the Marking and Signi
