In attending to the subject of this Essay we have been led to observe the different ways, in which the mind of man may be brought into a position tending to exhibit its powers in a less creditable and prepossessing point of view, than that in which all men, idiots and extraordinary cases excepted, are by nature qualified to appear. Many, not contented with those occupations, modest and humble in certain cases, to which their endowments and original bent had designed them, shew themselves immoderately set upon more alluring and splendid pursuits in which they are least qualified to excel. Other instances there are, still more entitled to our regret, where the individual is seen to be gifted with no ordinary qualities, where his morning of life has proved auspicious, and the highest expectations were formed of a triumphant career, while yet in the final experiment he has been found wanting, and the "voyage of his life" has passed "in shallows and in miseries." But our survey of the subject of which I treat will not be complete, unless we add to what has been said, another striking truth respecting the imperfection of man collectively taken. The examples of which the history of our species consists, not only abound in cases, where, from mistakes in the choice of life, or radical and irremediable imperfection in the adventurer, the most glaring miscarriages are found to result,--but it is also true, that all men, even the most illustrious, have some fatal weakness, obliging both them and their rational admirers to confess, that they partake of human frailty, and belong to a race of beings which has small occasion to be proud. Each man has his assailable part. He is vulnerable, though it be only like the fabled Achilles in his heel. We are like the image that Nebuchadnezzar saw in his dream, of which though the head was of fine gold, and the breast and the arms were silver, yet the feet were partly only of iron, and partly of clay. No man is whole and entire, armed at all points, and qualified for every undertaking, or even for any one undertaking, so as to carry it through, and to make the achievement he would perform, or the work he would produce, in all its parts equal and complete.
