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.’ 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.’
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. He would say, with a significant look and decisive tone, ‘It is not so. Do not tell this again.’ He inculcated upon all his friends the importance of perpetual vigilance against the slightest degrees of falsehood.
I’d love to have seen Johnson seen the twitters and whatsapps and facebooks of the world…
