It can, indeed, raise no wonder that temerity has been generally censured; for it is one of the vices with which few can be charged, and which therefore, great numbers are ready to condemn. It is the vice of noble and generous minds, the exuberance of magnanimity, and the ebullition of genius; and is therefore not regarded with much tenderness, because it never flatters us by that appearance of softness and imbecility which is commonly necessary to conciliate compassion. But if the same attention had been applied to the search of arguments against the folly of pre-supposing impossibilities, and anticipating frustration, I know not whether many would not have been roused to usefulness, who, having been taught to confound prudence with timidity, never ventured to excel, lest they should unfortunately fail. It is necessary to distinguish our own interest from that of others, and that distinction will perhaps assist us in fixing the just limits of caution and adventurousness. In an undertaking that involves the happiness or the safety of many, we have certainly no right to hazard more than is allowed by those who partake the danger; but where only ourselves can suffer by miscarriage, we are not confined within such narrow limits; and still less is the reproach of temerity, when numbers will receive advantage by success, and only one be incommoded by failure. Men are generally willing to hear precepts by which ease is favoured; and as no resentment is raised by general representations of human folly, even in those who are most eminently jealous of comparative reputation, we confess, without reluctance, that vain man is ignorant of his own weakness, and therefore frequently presumes to attempt what he can never accomplish; but it ought likewise to be remembered, that man is no less ignorant of his own powers, and might perhaps have accomplished a thousand designs, which the prejudices of cowardice restrained him from attempting. It is observed in the golden verses of Pythagoras, that "Power is never far from necessity." The vigour of the human mind quickly appears, when there is no longer any place for doubt and hesitation, when diffidence is absorbed in the sense of danger, or overwhelmed by some resistless passion. We then soon discover, that difficulty is, for the most part, the daughter of idleness, that the obstacles with which our way seemed to be obstructed were only phantoms, which we believed real, because we durst not advance to a close examination; and we learn that it is impossible to determine without experience how much constancy may endure, or perseverance perform.
