From causes which might be traced in the history and development of English society and government, the general habit and practice of the English mind is compromise. No idea is carried out to more than a small portion of its legitimate consequences. Neither by the generality of our speculative thinkers, nor in the practice of the nation, are the principles which are professed ever thoroughly acted upon; something always stops the application half way. This national habit has consequences of very various character, of which the following is one. It is natural to minds governed by habit (which is the character of the English more than of any other civilized people) that their tastes and inclinations become accommodated to their habitual practice; and as in England no principle is ever fully carried out, discordance between principles and practice has come to be regarded, not only as the natural, but as the desirable state. This is no an epigram, or a paradox, but a sober description of the tone of sentiment commonly found in Englishman. They never feel themselves safe unless they are living under the shadow of some convention fiction — some agreement to say one thing and mean another.
That is from Mill’s Vindication of the French Revolution of February 1848.
