Some, whatsoever is beyond their reach, will seem to despise, or make light of it, as impertinent or curious; and so would have their ignorance seem judgment. Some are never without a difference, and commonly by amusing men with a subtilty, blanch the matter; of whom A. Gellius saith, Hominem delirum, qui verborum minutiis rerum frangit pondera. Of which kind also, Plato, in his Protagoras, bringeth in Prodicus in scorn, and maketh him make a speech, that consisteth of distinction from the beginning to the end. Generally, such men in all deliberations find ease to be of the negative side, and affect a credit to object and foretell difficulties; for when propositions are denied, there is an end of them; but if they be allowed, it requireth a new work; which false point of wisdom is the bane of business.
