So a fool is one that hath lost his wisdom, and right notion of God and divine things which were communicated to man by creation; one dead in sin, yet one not so much void of rational faculties as of grace in those faculties, not one that wants reason, but abuses his reason. In Scripture the word signifies foolish.
The wise man has his follies, no less than the fool; but it has been said that herein lies the difference,the follies of the fool are known to the world, but are hidden from himself; the follies of the wise are known to himself, but hidden from the world. A harmless hilarity and a buoyant cheerfulness are not infrequent concomitants of genius; and we are never more deceived than when we mistake gravity for greatness, solemnity for science, and pomposity for erudition.
Some things are done by men, though not through outward force and impulsion, though not against, yet without, their wills; as in alienation of mind, or any like inevitable utter absence of wit and judgment.
Foolishness, being properly a mans deviation from right reason, in point of practice must needs consist in his pitching upon such an end as is unsuitable to his condition, or pitching upon means unsuitable to the compassing of his end.
