Fourthly, The tickling pricks of incontinency are blunted by an eager study; for from thence proceedeth an incredible resolution of the spirits, that oftentimes there do not remain so many behind as may suffice to push and thrust forwards the generative resudation to the places thereto appropriated, and therewithal inflate the cavernous nerve whose office is to ejaculate the moisture for the propagation of human progeny.  Lest you should think it is not so, be pleased but to contemplate a little the form, fashion, and carriage of a man exceeding earnestly set upon some learned meditation, and deeply plunged therein, and you shall see how all the arteries of his brains are stretched forth and bent like the string of a crossbow, the more promptly, dexterously, and copiously to suppeditate, furnish, and supply him with store of spirits sufficient to replenish and fill up the ventricles, seats, tunnels, mansions, receptacles, and cellules of the common sense,—­of the imagination, apprehension, and fancy,—­of the ratiocination, arguing, and resolution,—­as likewise of the memory, recordation, and remembrance; and with great alacrity, nimbleness, and agility to run, pass, and course from the one to the other, through those pipes, windings, and conduits which to skilful anatomists are perceivable at the end of the wonderful net where all the arteries close in a terminating point; which arteries, taking their rise and origin from the left capsule of the heart, bring through several circuits, ambages, and anfractuosities, the vital, to subtilize and refine them to the ethereal purity of animal spirits.  Nay, in such a studiously musing person you may espy so extravagant raptures of one as it were out of himself, that all his natural faculties for that time will seem to be suspended from each their proper charge and office, and his exterior senses to be at a stand.  In a word, you cannot otherwise choose than think that he is by an extraordinary ecstasy quite transported out of what he was, or should be; and that Socrates did not speak improperly when he said that philosophy was nothing else but a meditation upon death.  This possibly is the reason why Democritus deprived himself of the sense of seeing, prizing at a much lower rate the loss of his sight than the diminution of his contemplations, which he frequently had found disturbed by the vagrant, flying-out strayings of his unsettled and roving eyes.  Therefore is it that Pallas, the goddess of wisdom, tutoress and guardianess of such as are diligently studious and painfully industrious, is, and hath been still accounted a virgin.  The Muses upon the same consideration are esteemed perpetual maids; and the Graces, for the like reason, have been held to continue in a sempiternal pudicity.
