"Et quo quemque modo fugiatque feratque laborem." ["And how you may shun or sustain every hardship." --Virgil, AEneid, iii. 459.] by what secret springs we move, and the reason of our various agitations and irresolutions: for, methinks the first doctrine with which one should season his understanding, ought to be that which regulates his manners and his sense; that teaches him to know himself, and how both well to dig and well to live. Amongst the liberal sciences, let us begin with that which makes us free; not that they do not all serve in some measure to the instruction and use of life, as all other things in some sort also do; but let us make choice of that which directly and professedly serves to that end. If we are once able to restrain the offices of human life within their just and natural limits, we shall find that most of the sciences in use are of no great use to us, and even in those that are, that there are many very unnecessary cavities and dilatations which we had better let alone, and, following Socrates' direction, limit the course of our studies to those things only where is a true and real utility: "Sapere aude; Incipe; Qui recte vivendi prorogat horam, Rusticus exspectat, dum defluat amnis; at ille Labitur, et labetur in omne volubilis oevum." ["Dare to be wise; begin! he who defers the hour of living well is like the clown, waiting till the river shall have flowed out: but the river still flows, and will run on, with constant course, to ages without end."--Horace, Ep., i. 2.] 'Tis a great foolery to teach our children: "Quid moveant Pisces, animosaque signa Leonis, Lotus et Hesperia quid Capricornus aqua," ["What influence Pisces have, or the sign of angry Leo, or Capricorn, washed by the Hesperian wave."--Propertius, iv. I, 89.] the knowledge of the stars and the motion of the eighth sphere before their own: ["What care I about the Pleiades or the stars of Taurus?" --Anacreon, Ode, xvii. 10.] Anaximenes writing to Pythagoras, "To what purpose," said he, "should I trouble myself in searching out the secrets of the stars, having death or slavery continually before my eyes?" for the kings of Persia were at that time preparing to invade his country. Every one ought to say thus, "Being assaulted, as I am by ambition, avarice, temerity, superstition, and having within so many other enemies of life, shall I go ponder over the world's changes?"
