As I practised conjecture more, I learned to trust it less; and after I had printed a few plays, resolved to insert none of my own readings in the text. Upon this caution I now congratulate myself, for every day encreases my doubt of my emendations. Since I have confined my imagination to the margin, it must not be considered as very reprehensible, if I have suffered it to play some freaks in its own dominion. There is no danger in conjecture, if it be proposed as conjecture; and while the text remains uninjured, those changes may be safely offered, which are not considered even by him that offers them as necessary or safe. If my readings are of little value, they have not been ostentatiously displayed or importunately obtruded. I could have written longer notes, for the art of writing notes is not of difficult attainment. The work is performed, first by railing at the stupidity, negligence, ignorance, and asinine tastelessness of the former editors, and shewing, from all that goes before and all that follows, the inelegance and absurdity of the old reading; then by proposing something, which to superficial readers would seem specious, but which the editor rejects with indignation; then by producing the true reading, with a long paraphrase, and concluding with loud acclamations on the discovery, and a sober wish for the advancement and prosperity of genuine criticism. All this may be done, and perhaps done sometimes without impropriety. But I have always suspected that the reading is right, which requires many words to prove it wrong; and the emendation wrong, that cannot without so much labour appear to be right. The justness of a happy restoration strikes at once, and the moral precept may be well applied to criticism, quod dubitas ne feceris. To dread the shore which he sees spread with wrecks, is natural to the sailor. I had before my eye, so many critical adventures ended in miscarriage, that caution was forced upon me. I encountered in every page Wit struggling with its own sophistry, and Learning confused by the multiplicity of its views. I was forced to censure those whom I admired, and could not but reflect, while I was dispossessing their emenations, how soon the same fate might happen to my own, and how many of the readings which I have corrected may be some other editor defended and established. Criticks, I saw, that other's names efface, And fix their own, with labour, in the place; Their own, like others, soon their place resign'd, Or disappear'd, and left the first behind.--Pope.
