above their merit at first, they are afterwards depressed below it; nor can the brightest elegance of diction, or most artful subtilty of reasoning, hope for so much esteem from those whose regard is no longer quickened by curiosity or pride.
It is indeed the fate of controvertists, even when they contend for philosophical or theological truth, to 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 enquiring what cavils were produced against him, or by what proofs they were confuted.
