Thomas Carlyle on Irony and SarcasmThomas Carlyle, Sartor Resartus: The Life and Opinions of Herr Teufelsdröckh (1833), pp. 134-5.
Often, notwithstanding, was I blamed, and by half-strangers hated, for my so-called Hardness, my Indifferentism towards men; and the seemingly ironic tone I had adopted, as my favorite dialect in conversation. Alas, the panoply of Sarcasm was but a buckram case, wherein I had striven to envelope myself; that so my own poor Person might live safe there, and in all friendliness, being no longer exasperated by wounds. Sarcasm I now see to be, in general, the language of the Devil; for which reason I have long since as good as renounced it. But how many individuals did I, in those days, provoke into some degree of hostility thereby! An ironic man, with his sly stillness, and ambuscading ways, more especially a young ironic man, from whom it is least expected, may be viewed as a pest to society.
