be soon laid aside and slighted. Either the question is decided, and there is no more place for doubt and opposition; or mankind despair of understanding it, and grow weary of disturbance, content themselves with quiet ignorance, and refuse to be harassed with labours which they have no hopes of recompensing with knowledge. The authors of new discoveries may surely expect to be reckoned among those, whose writings are secure of veneration yet it often happens that the general reception of a doctrine obscures the books in which it was delivered. When any tenet is generally received and adopted as an incontrovertible principle, we seldom look back to the arguments upon which it was first established, or can bear that tediousness of deduction, and multiplicity of evidence, by which its author was forced to reconcile it to prejudice, and fortify it in the weakness of novelty against obstinacy and envy. It is well known how much of our philosophy is derived from Boyle's discovery of the qualities of the air; yet of those who now adopt or enlarge his theory, very few have read the detail of his experiments. His name is, indeed, reverenced; but his works are neglected; we are contented to know, that he conquered his opponents, without inquiring what cavils were produced against him, or by what proofs they were confuted. Some writers apply themselves to studies boundless and inexhaustible, as experiments and natural philosophy. These are always lost in successive compilations as new advances are made, and former observations become more familiar. Others spend their lives in remarks on language, or explanations of antiquities, and only afford materials for lexicographers and commentators, who are themselves overwhelmed by subsequent collectors, that equally destroy the memory of their predecessors by amplification, transposition, or contraction. Every new system of nature gives birth to a swarm of expositors, whose business is to explain and illustrate it, and who can hope to exist no longer than the founder of their sect preserves his reputation. There are, indeed, few kinds of composition from which an author, however learned or ingenious, can hope a long continuance of fame. He who has carefully studied human nature, and can well describe it, may with most reason flatter his ambition. Bacon, among all his pretensions to the regard of posterity, seems to have pleased himself chiefly with his Essays, which come home to men's business and bosoms, and of which, therefore, he declares his expectation, that they will live as long as books last. It may, however, satisfy an honest and benevolent mind to have been useful, though less conspicuous; nor will he that extends his hopes to higher rewards, be so much anxious to obtain praise, as to discharge the duty which Providence assigns him.
