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 signify the appetites, aversions, and passions of man's mind; and of their use and abuse, I shall speak when I have spoken of the passions.
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 signify our conceptions, and all our affections are but conceptions, when we conceive the same things differently, we can hardly avoid 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 must take heed of words; which besides the signification of what we imagine of their nature, have a signification also of the nature, disposition, and interest of the speaker; such as are the names of virtues and vices; for one man calleth "wisdom," what another calleth "fear"; and one "cruelty," what another "justice"; one "prodigality," what another "magnanimity"; and 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.
