When he began his travels, or when be concluded them, there is no certain account; nor do there remain any observations made by him in his passage through those countries which he visited.  To consider, therefore, what pleasure or instruction might have been received from the remarks of a man so curious and diligent, would be voluntarily to indulge a painful reflection, and load the imagination with a wish, which, while it is formed, is known to be vain.  It is, however, to be lamented, that those who are most capable of improving mankind, very frequently neglect to communicate their knowledge; either because it is more pleasing to gather ideas than to impart them, or because, to minds naturally great, few things appear of so much importance as to deserve the notice of the publick.

About the year 1634 [72], he is supposed to have returned to London; and the next year to have written his celebrated treatise, called Religio Medici, “the religion of a physician [73],” which he declares himself never to have intended for the press, having composed it only for his own exercise and entertainment.  It, indeed, contains many passages, which, relating merely to his own person, can be of no great importance to the publick; but when it was written, it happened to him as to others, he was too much pleased with his performance, not to think that it might please others as much; he, therefore, communicated it to his friends, and receiving, I suppose, that exuberant applause with which every man repays the grant of perusing a manuscript, he was not very diligent to obstruct his own praise by recalling his papers, but suffered them to wander from hand to hand, till, at last, without his own consent, they were, in 1642, given to a printer.

This has, perhaps, sometimes befallen others; and this, I am willing to believe, did really happen to Dr. Browne:  but there is, surely, some reason to doubt the truth of the complaint so frequently made of surreptitious editions.  A song, or an epigram, may be easily printed without the author’s knowledge; because it may be learned when it is repeated, or may be written out with very little trouble; but a long treatise, however elegant, is not often copied by mere zeal or curiosity, but may be worn out in passing from hand to hand, before it is multiplied by a transcript.  It is easy to convey an imperfect book, by a distant hand, to the press, and plead the circulation of a false copy, as an excuse for publishing the true, or to correct what is found faulty or offensive, and charge the errours on the transcriber’s depravations.

This is a stratagem, by which an author, panting for fame, and yet afraid of seeming to challenge it, may at once gratify his vanity, and preserve the appearance of modesty; may enter the lists, and secure a retreat; and this candour might suffer to pass undetected, as an innocent fraud, but that, indeed, no fraud is innocent; for the confidence which makes the happiness of society is, in some degree, diminished by every man whose practice is at variance with his words.
