Omnis divinæ atque humanæ eruditionis elementa tria, Nosse, Velle, Posse; quorum principium unum Mens; cujus oculus Ratio; cui lumen * * præbet Deus.
VICO.
Naturam hominis hanc Deus ipse voluit, ut duarum rerum cupidus et appetens esset, religionis et sapientiæ. Sed homines ideo falluntur, quod aut religionem suscipiunt omissa sapientia; aut sapientiæ soli student omissa religione; cum alterum sine altero esse non possit verum.

THE AUTHOR'S PREFACE.
AN Author has three points to settle: to what sort his work belongs, for what description of readers it is intended, and the specific end, or object, which it is to answer. There is indeed a preliminary question respecting the end which the writer himself has in view, whether the number of purchasers, or the benefit of the readers. But this may be safely passed by; since where the book itself or the known principles of the writer do not supersede the question, there will seldom be sufficient strength of character for good or for evil, to afford much chance of its being either distinctly put or fairly answered.
I shall proceed therefore to state as briefly as possible the intentions of the present volume in reference to the three first-mentioned points, viz. What? For Whom? and For what?
I. What? The answer is contained in the title-page.[3] It belongs to the class of didactic works. Consequently, those who neither wish instruction for themselves, nor assistance in instructing others, have no interest in its contents. Sis sus, sis Divus: sum caltha, et non tibi spiro.
