The objects around us, beside their separate appearances, have their relations to each other. They suggest, when compared, what would not occur when they are considered apart; they have their effects, and mutual influences; they exhibit, in like circumstances, similar operations, and uniform consequences. When we have found and expressed the points in which the uniformity of their operations consists, we have ascertained a physical law. Many such laws, and even the most important, are known to the vulgar, and occur upon the smallest degrees of reflection; but others are hid under a seeming confusion, which ordinary talents cannot remove; and are therefore the objects of study, long observation, and superior capacity. The faculties of penetration and judgment, are, by men of business, as well as of science, employed to unravel intricacies of this sort; and the degree of sagacity with which either is endowed, is to be measured by the success with which they are able to find general rules, applicable to a variety of cases that seemed to have nothing in common, and to discover important distinctions between subjects which the vulgar are apt to confound. To collect a multiplicity of particulars under general heads, and to refer a variety of operations to their common principle, is the object of science. To do the same thing, at least within the range of his active engagements, is requisite to the man of pleasure, or business; and it would seem, that the studious and the active are so far employed in the same task, from observation and experience, to find the general views under which their objects may be considered, and the rules which may be usefully applied in the detail of their conduct. They do not always apply their talents to different subjects; and they seem to be distinguished chiefly by the unequal reach and variety of their remarks, or by the intentions which they severally have in collecting them. Whilst men continue to act from appetites and passions, leading to the attainment of external ends, they seldom quit the view of their objects in detail, to go far in the road of general inquiries. They measure the extent of their own abilities, by the promptitude with which they apprehend what is important in every subject, and the facility with which they extricate themselves on every trying occasion. And these, it must be confessed, to a being who is destined to act in the midst of difficulties, are the proper test of capacity and force. The parade of words and general reasonings, which sometimes carry an appearance of so much learning and knowledge, are of little avail in the conduct of life. The talents from which they proceed, terminate in mere ostentation, and are seldom connected with that superior discernment which the active apply in times of perplexity; much less with that intrepidity and force of mind which are required in passing through difficult scenes.
