I. A man must not only consider how daily his life wasteth and decreaseth, but this also, that if he live long, he cannot be certain, whether his understanding shall continue so able and sufficient, for either discreet consideration, in matter of businesses; or for contemplation: it being the thing, whereon true knowledge of things both divine and human, doth depend. For if once he shall begin to dote, his respiration, nutrition, his imaginative, and appetitive, and other natural faculties, may still continue the same: he shall find no want of them. But how to make that right use of himself that he should, how to observe exactly in all things that which is right and just, how to redress and rectify all wrong, or sudden apprehensions and imaginations, and even of this particular, whether he should live any longer or no, to consider duly; for all such things, wherein the best strength and vigour of the mind is most requisite; his power and ability will be past and gone. Thou must hasten therefore; not only because thou art every day nearer unto death than other, but also because that intellective faculty in thee, whereby thou art enabled to know the true nature of things, and to order all thy actions by that knowledge, doth daily waste and decay: or, may fail thee before thou die.
II. This also thou must observe, that whatsoever it is that naturally doth happen to things natural, hath somewhat in itself that is pleasing and delightful: as a great loaf when it is baked, some parts of it cleave as it were, and part asunder, and make the crust of it rugged and unequal, and yet those parts of it, though in some sort it be against the art and intention of baking itself, that they are thus cleft and parted, which should have been and were first made all even and uniform, they become it well nevertheless, and have a certain peculiar property, to stir the appetite. So figs are accounted fairest and ripest then, when they begin to shrink, and wither as it were. So ripe olives, when they are next to putrefaction, then are they in their proper beauty. The hanging down of grapes--the brow of a lion, the froth of a foaming wild boar, and many other like things, though by themselves considered, they are far from any beauty, yet because they happen naturally, they both are comely, and delightful; so that if a man shall with a profound mind and apprehension, consider all things in the world, even among all those things which are but mere accessories and natural appendices as it were, there will scarce appear anything unto him, wherein he will not find matter of pleasure and delight. So will he behold with as much pleasure the true _rictus_ of wild beasts, as those which by skilful painters and other artificers are imitated. So will he be able to perceive the proper ripeness and beauty of old age, whether in man or woman: and whatsoever else it is that is beautiful and alluring in whatsoever is, with chaste and continent eyes he will soon find out and discern. Those and many other things will he discern, not credible unto every one, but unto them only who are truly and familiarly acquainted, both with nature itself, and all natural things.
