It is commonly observed that there is a disposition in men to complain of the viciousness and corruption of the age in which they live as greater than that of former ones; which is usually followed with this further observation, that mankind has been in that respect much the same in all times. Now, not to determine whether this last be not contradicted by the accounts of history; thus much can scarce be doubted, that vice and folly takes different turns, and some particular kinds of it are more open and avowed in some ages than in others; and, I suppose, it may be spoken of as very much the distinction of the present to profess a contracted spirit, and greater regards to self-interest, than appears to have been done formerly. Upon this account it seems worth while to inquire whether private interest is likely to be promoted in proportion to the degree in which self-love engrosses us, and prevails over all other principles; _or whether the contracted affection may not possibly be so prevalent as to disappoint itself_, _and even contradict its own and private good_. And since, further, there is generally thought to be some peculiar kind of contrariety between self-love and the love of our neighbour, between the pursuit of public and of private good; insomuch that when you are recommending one of these, you are supposed to be speaking against the other; and from hence arises a secret prejudice against, and frequently open scorn of, all talk of public spirit and real good-will to our fellow- creatures; it will be necessary to _inquire what respect benevolence hath to self-love_, _and the pursuit of private interest to the pursuit of public_: or whether there be anything of that peculiar inconsistence and contrariety between them over and above what there is between self-love and other passions and particular affections, and their respective pursuits. These inquiries, it is hoped, may be favourably attended to; for there shall be all possible concessions made to the favourite passion, which hath so much allowed to it, and whose cause is so universally pleaded: it shall be treated with the utmost tenderness and concern for its interests. In order to do this, as well as to determine the forementioned questions, it will be necessary to _consider the nature_, _the object_, _and end of that self-love_, _as distinguished from other principles or affections in the mind_, _and their respective objects_.
