As his understanding increased, the passions became stronger in proportion: and here is to be observed the wonderful wisdom of nature, or rather of the Great Author of nature, in the formation of the human system, that the passions given to us, especially those of the worst sort, are, for the most part, such opposites, that the one is a sufficient check upon the other.--The _pride_ of treating those beneath us with contempt, is restrained by the _fear_ of meeting the same usage from those above us.--A _sordid covetousness_ is controlled by _ostentation_.--_Sloth_ is roused by _ambition_, and so of the rest.--I have been told that when Natura, by the enticements of his companions, and his own eagerness to pursue the sports suitable to his years, had been drawn in to neglect his studies, he had often ran home on a sudden, and denied himself both food and sleep, till he had not only finished the task assigned him by his school-master, but also exceeded what was expected from him, instigated by the ambition of praise, and hope of being removed to a higher form.--But at other times again his love of play has rendered him totally forgetful of every thing besides, and all emulation in him absorbed in pleasure.--Thus hurried, as the different propensities prevailed, from one extreme to the other;--never in a medium, but always doing either more or less than was required of him. In like manner was his _avarice_ moderated by his _pity_;--an instance of which was this;--One morning having won at chuck-farthing, or some such game, all the money a poor boy was master of, and which he said had been given him to buy his breakfast, Natura was so much melted at his tears and complaints, that he generously returned to him the whole of what he had lost.--Greatly is it to be wished, the same sentiments of compassion would influence some of riper years, and make them scorn to take the advantage chance sometimes affords of ruining their fellow-creatures; but the misfortune is, that when we arrive at the state of perfect manhood, the _worst_ passions are apt to get the better of the more _noble_, as the prospect they present is more alluring to the eye of sense: all men (as I said before) being born with the same propensities, it is _virtue_ alone, or in other words, a strict _morality_, which prevents them from actuating alike in all.--But to return to the young Natura.
