He was a man of pleasing conversation, and was accompanied by a young gentleman, his son.
I mentioned that I had in my possession the Life of Sir Robert Sibbald, the celebrated Scottish antiquary, and founder of the Royal College of Physicians at Edinburgh, in the original manuscript in his own handwriting; and that it was I believed the most natural and candid account of himself that ever was given by any man. As an instance, he tells that the Duke of Perth, then Chancellor of Scotland, pressed him very much to come over to the Roman Catholick faith: that he resisted all his Grace's arguments for a considerable time, till one day he felt himself, as it were, instantaneously convinced, and with tears in his eyes ran into the Duke's arms, and embraced the ancient religion; that he continued very steady in it for some time, and accompanied his Grace to London one winter, and lived in his household; that there he found the rigid fasting prescribed by the church very severe upon him; that this disposed him to reconsider the controversy, and having then seen that he was in the wrong, he returned to Protestantism. I talked of some time or other publishing this curious life. MRS. THRALE. 'I think you had as well let alone that publication. To discover such weakness, exposes a man when he is gone.' JOHNSON. 'Nay, it is an honest picture of human nature. How often are the primary motives of our greatest actions as small as Sibbald's, for his re-conversion[641].' MRS. THRALE. 'But may they not as well be forgotten?' JOHNSON. 'No, Madam, a man loves to review his own mind. That is the use of a diary, or journal[642].' LORD TRIMLESTOWN. 'True, Sir. As the ladies love to see themselves in a glass; so a man likes to see himself in his journal.' BOSWELL. 'A very pretty allusion.' JOHNSON. 'Yes, indeed.' BOSWELL. 'And as a lady adjusts her dress before a mirror, a man adjusts his character by looking at his journal.' I next year found the very same thought in Atterbury's Funeral Sermon on Lady Cutts; where, having mentioned her Diary, he says, 'In this glass she every day dressed her mind.' This is a proof of coincidence, and not of plagiarism; for I had never read that sermon before.
Next morning, while we were at breakfast, Johnson gave a very earnest recommendation of what he himself practised with the utmost conscientiousness: I mean a strict attention to truth, even in the most minute particulars. 'Accustom your children (said he) constantly to this; if a thing happened at one window, and they, when relating it, say that it happened at another, do not let it pass, but instantly check them; you do not know where deviation from truth will end.' BOSWELL. 'It may come to the door: and when once an account is at all varied in one circumstance, it may by degrees be varied so as to be totally different from what really happened.' Our lively hostess, whose fancy was impatient of the rein, fidgeted at this, and ventured to say, 'Nay, this is too much. If Mr. Johnson should forbid me to drink tea, I would comply, as I should feel the restraint only twice a day; but little variations in narrative must happen a thousand times a day, if one is not perpetually watching.' JOHNSON. 'Well, Madam, and you ought to be perpetually watching. It is more from carelessness about truth than from intentional lying, that there is so much falsehood in the world[643].'
In his review of Dr. Warton's Essay on the Writings and Genius of Pope, Johnson has given the following salutary caution upon this subject:--
'Nothing but experience could evince the frequency of false information, or enable any man to conceive that so many groundless reports should be propagated, as every man of eminence may hear of himself. Some men relate what they think, as what they know; some men of confused memories and habitual inaccuracy, ascribe to one man what belongs to another; and some talk on, without thought or care. A few men are sufficient to broach falsehoods, which are afterwards innocently diffused by successive relaters[644].'
Had he lived to read what Sir John Hawkins and Mrs. Piozzi have related concerning himself, how much would he have found his observation illustrated. He was indeed so much impressed with the prevalence of falsehood, voluntary or unintentional, that I never knew any person who upon hearing an extraordinary circumstance told, discovered more of the incredulus odi[645]. He would say, with a significant look and decisive tone, 'It is not so. Do not tell this again[646].' He inculcated upon all his friends the importance of perpetual vigilance against the slightest degrees of falsehood; the effect of which, as Sir Joshua Reynolds observed to me, has been, that all who were of his school are distinguished for a love of truth and accuracy, which they would not have possessed in the same degree, if they had not been acquainted with Johnson[647].
Talking of ghosts, he said, 'It is wonderful that five thousand years have now elapsed since the creation of the world, and still it is undecided whether or not there has ever been an instance of the spirit of any person appearing after death.
