It often happens, whatever be the cause, that impatience of labour, or dread of miscarriage, seizes those who are most distinguished for quickness of apprehension; and that they who might with greatest reason promise themselves victory, are least willing to hazard the encounter. This diffidence, where the attention is not laid asleep by laziness, or dissipated by pleasures, can arise only from confused and general views, such as negligence snatches in haste, or from the disappointment of the first hopes formed by arrogance without reflection. To expect that the intricacies of science will be pierced by a careless glance, or the eminences of fame ascended without labour, is to expect a particular privilege, a power denied to the rest of mankind; but to suppose that the maze is inscrutable to diligence, or the heights inaccessible to perseverance, is to submit tamely to the tyranny of fancy, and enchain the mind in voluntary shackles. It is the proper ambition of the heroes in literature to enlarge the boundaries of knowledge by discovering and conquering new regions of the intellectual world. To the success of such undertakings perhaps some degree of fortuitous happiness is necessary, which no man can promise or procure to himself; and therefore doubt and irresolution may be forgiven in him that ventures into the unexplored abysses of truth, and attempts to find his way through the fluctuations of uncertainty, and the conflicts of contradiction. But when nothing more is required, than to pursue a path already beaten, and to trample obstacles which others have demolished, why should any man so much distrust his own intellect as to imagine himself unequal to the attempt? It were to be wished that they who devote their lives to study would at once believe nothing too great for their attainment, and consider nothing as too little for their regard; that they would extend their notice alike to science and to life, and unite some knowledge of the present world to their acquaintance with past ages and remote events. Nothing has so much exposed men of learning to contempt and ridicule, as their ignorance of things which are known to all but themselves. Those who have been taught to consider the institutions of the schools, as giving the last perfection to human abilities, are surprised to see men wrinkled with study, yet wanting to be instructed in the minute circumstances of propriety, or the necessary forms of daily transaction; and quickly shake off their reverence for modes of education, which they find to produce no ability above the rest of mankind. "Books," says Bacon, "can never teach the use of books." The student must learn by commerce with mankind to reduce his speculations to practice, and accommodate his knowledge to the purposes of life.
