With regard to simple propositions, where the terms are understood, and the whole subject is comprehended at once, there is such an uniformity of sentiment among all human beings, that, for many ages, a very numerous set of notions were supposed to be innate, or necessarily co-existent with the faculty of reason: it being imagined, that universal agreement could proceed only from the invariable dictates of the universal parent. In questions diffuse and compounded, this similarity of determination is no longer to be expected. At our first sally into the intellectual world, we all march together along one straight and open road; but as we proceed further, and wider prospects open to our view, every eye fixes upon a different scene; we divide into various paths, and, as we move forward, are still at a greater distance from each other. As a question becomes more complicated and involved, and extends to a greater number of relations, disagreement of opinion will always be multiplied; not because we are irrational, but because we are finite beings, furnished with different kinds of knowledge, exerting different degrees of attention, one discovering consequences which escape another, none taking in the whole concatenation of causes and effects, and most comprehending but a very small part, each comparing what he observes with a different criterion, and each referring it to a different purpose. Where, then, is the wonder, that they who see only a small part should judge erroneously of the whole? or that they, who see different and dissimilar parts, should judge differently from each other? Whatever has various respects, must have various appearances of good and evil, beauty or deformity; thus, the gardener tears up as a weed, the plant which the physician gathers as a medicine; and "a general," says Sir Kenelm Digby, "will look with pleasure over a plain, as a fit place on which the fate of empires might be decided in battle, which the farmer will despise as bleak and barren, neither fruitful of pasturage, nor fit for tillage[n]." [n] Livy has described the Achaean leader, Philopaemen, as actually so exercising his thoughts whilst he wandered among the rocky passes of the Morea, xxxv. 28. In the graphic page of the Roman historian, as in the stanzas of the "Ariosto of the North:" "From shingles grey the lances start, "The bracken bush sends forth the dart, "The rushes and the willow wand "Are bristling into axe and brand." Lady of the Lake. Canto v. 9. Two men examining the same question proceed commonly like the physician and gardener in selecting herbs, or the farmer and hero looking on the plain; they bring minds impressed with different notions, and direct their inquiries to different ends; they form, therefore, contrary conclusions, and each wonders at the other's absurdity.
