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.
But whatever pleasure may be found in the review of distresses when art or courage has surmounted them, few will be persuaded to wish that they may be awakened by want, or terrour, to the conviction of their own abilities. Every one should therefore endeavour to invigorate himself by reason and reflection, and determine to exert the latent force that nature may have reposed in him, before the hour of exigence comes upon him, and compulsion shall torture him to diligence. It is below the dignity of a reasonable being to owe that strength to necessity which ought always to act at the call of choice, or to need any other motive to industry than the desire of performing his duty.
Reflections that may drive away despair, cannot be wanting to him who considers how much life is now advanced beyond the state of naked, undisciplined, uninstructed nature. Whatever has been effected for convenience or elegance, while it was yet unknown, was believed impossible; and therefore would never have been attempted, had not some, more daring than the rest, adventured to bid defiance to prejudice and censure. Nor is there yet any reason to doubt that the same labour would be rewarded with the same success. There are qualities in the products of nature yet undiscovered, and combinations in the powers of art yet untried. It is the duty of every man to endeavour that something may be added by his industry to the hereditary aggregate of knowledge and happiness. To add much can indeed be the lot of few, but to add something, however little, every one may hope; and of every honest endeavour, it is certain, that, however unsuccessful, it will be at last rewarded.
