has a special eye (though it does not despise the other), so that the young fry may be brought up to prove good in the end, and serve their country well in whatever position they may be placed. For the performance of this end I take it that this elementary course is most sufficient, being the best means of perfecting all those powers with which nature endows our race, by using those studies which art and reflection appoint, and those methods which nature herself suggests. For the end of education and training is to help nature to her perfection in the complete development of all the various powers. This is what I mean by following nature, not counterfeiting her in her own proper work by foolish imitation, or perverse attempt to produce her effects, like an Apelles in portraiture or an Archimedes in the laws of motion, but after considering and marking with good judgment what are the natural tendencies and inclinations, to frame a scheme of education in consonance with these, and bring to perfection by art all those powers which nature bestows in frank abundance. For the physical life of man, in order to maintain and develop both the individual and the species, nature has provided organs that receive, prepare and distribute nourishment for the body, and has, besides, given us for self-preservation the power of perceiving all sensible things by means of feeling, hearing, seeing, smelling, and tasting. These qualities of the outward world, being apprehended by the understanding and examined by the judgment, are handed over to the memory, and afterwards prove our chief--nay, our only--means of obtaining further knowledge. Moreover, we have also a power of movement, either under the influence of emotion or by the enticement of desire, either for the direct purposes of life, as in the action of the pulse and in breathing, or for outward action, such as walking, running, or leaping. To serve the end both of sense-perception and of motion, nature has planted in the body a brain, the prince of all our organs, which by spreading its channels through every part of our frame produces all the effects through which sense passes into motion. Further, our soul has in it a desire to obtain what it holds to be good, and to avoid what it thinks evil. This desire is stirred either by quiet allurement or by violent incitement, and when once it is inflamed it strives to compass its end. To satisfy this desire nature has given us a heart to kindle heat, and as the sense is moved by the qualities of the object, and motion is effected by means of sinews, so appetite, being stirred by the object of desire or repulsion, is supplied with the means of satisfying itself.
