"All this criticism [of Hume] proceeds upon the erroneoushypothesis that he was a dogmatist.

This word and its derivatives are often written with c instead of k in the first syllable, sceptic, sceptical, scepticism, etc. Dr. Johnson, struck with the extraordinary irregularity of giving c its heavysoundtill e, altered the spelling, and his example has been followed by most of the lexicographers who have succeeded him; yet the prevalent practice among English writers and printers is in favor of the another mode. In the United States this practice is reversed, a big and increasing majority of educated persons preferring the orthography which is most in accordance with etymology and analogy.
