To excel in any of these forms of writing will require a particular cultivation of the genius: whoever can attain to excellence, will be certain to engage a set of readers, whom no other method would have equally allured; and he that communicates truth with success, must be numbered among the first benefactors to mankind. The same observation may be extended likewise to the passions: their influence is uniform, and their effects nearly the same in every human breast: a man loves and hates, desires and avoids, exactly like his neighbour; resentment and ambition, avarice and indolence, discover themselves by the same symptoms in minds distant a thousand years from one another. Nothing, therefore, can be more unjust, than to charge an author with plagiarism, merely because he assigns to every cause its natural effect; and makes his personages act, as others in like circumstances have always done. There are conceptions in which all men will agree, though each derives them from his own observation: whoever has been in love, will represent a lover impatient of every idea that interrupts his meditations on his mistress, retiring to shades and solitude, that he may muse without disturbance on his approaching happiness, or associating himself with some friend that flatters his passion, and talking away the hours of absence upon his darling subject. Whoever has been so unhappy as to have felt the miseries of long-continued hatred, will, without any assistance from ancient volumes, be able to relate how the passions are kept in perpetual agitation, by the recollection of injury and meditations of revenge; how the blood boils at the name of the enemy, and life is worn away in contrivances of mischief. Every other passion is alike simple and limited, if it be considered only with regard to the breast which it inhabits; the anatomy of the mind, as that of the body, must perpetually exhibit the same appearances; and though by the continued industry of successive inquirers, new movements will be from time to time discovered, they can affect only the minuter parts, and are commonly of more curiosity than importance.
