For though wee usually have one name of Wisedome for them both; yet the Latines did always distinguish between Prudentia and Sapientia, ascribing the former to Experience, the later to Science.

But to make their difference appeare more cleerly, let us suppose one man endued with an excellent naturall use, and dexterity in handling his armes; and another to have added to that dexterity, an acquired Science, of where he can offend, or be offended by his adversarie, in every possible posture, or guard: The ability of the former, would be to the ability of the later, as Prudence to Sapience; both usefull; but the later infallible.

But they that trusting onely to the authority of books, follow the blind blindly, are like him that trusting to the false rules of the master of fence, ventures praesumptuously upon an adversary, that either kills, or disgraces him.
Signes Of Science The signes of Science, are some, certain and infallible; some, uncertain.

Certain, when he that pretendeth the Science of any thing, can teach the same; that is to say, demonstrate the truth thereof perspicuously to another: Uncertain, when onely some particular events answer to his pretence, and upon many occasions prove so as he sayes they must.

Signes of prudence are all uncertain; because to observe by experience, and remember all circumstances that may alter the successe, is impossible.
