If the importance of the truth be requisite to compleat the pleasure, 'tis not on account of any considerable addition, which of itself it brings to our enjoyment, but only because 'tis, in some measure, requisite to fix our attention. When we are careless and inattentive, the same action of the understanding has no effect upon us, nor is able to convey any of that satisfaction, which arises from it, when we are in another disposition.
But beside the action of the mind, which is the principal foundation of the pleasure, there is likewise requir'd a degree of success in the attainment of the end, or the discovery of that truth we examine. Upon this head I shall make a general remark, which may be useful on many occasions, viz. that where the mind pursues any end with passion; tho' that passion be not deriv'd originally from the end, but merely from the action and pursuit; yet by the natural course of the affections, we acquire a concern for the end itself, and are uneasy under any disappointment we meet with in the pursuit of it. This proceeds from the relation and parallel direction of the passions above-mention'd.
To illustrate all this by a similar instance, I shall observe, that there cannot be two passions more nearly resembling each other, than those of hunting and philosophy, whatever disproportion may at first sight appear betwixt them. 'Tis evident, that the pleasure of hunting consists in the action of the mind and body; the motion, the attention, the difficulty, and the uncertainty. 'Tis evident likewise, that these actions must be attended with an idea of utility, in order to their having any effect upon us. A man of the greatest fortune, and the farthest remov'd from avarice, tho' he takes a pleasure in hunting after partridges and pheasants, feels no satisfaction in shooting crows and magpies; and that because he considers the first as fit for the table, and the other as entirely useless. Here 'tis certain, that the utility or importance of
