When I come across a writer of this sort, I do not much mind his lying; the practice is much too well established for that, even with professed philosophers; I am only surprised at his expecting to escape detection. Now I am myself vain enough to cherish the hope of bequeathing something to posterity; I see no reason for resigning my right to that inventive freedom which others enjoy; and, as I have no truth to put on record, having lived a very humdrum life, I fall back on falsehood—but falsehood of a more consistent variety; for I now make the only true statement you are to expect—that I am a liar. This confession is, I consider, a full defence against all imputations. My subject is, then, what I have neither seen, experienced, nor been told, what neither exists nor could conceivably do so. I humbly solicit my readers’ incredulity.
