But when the citizens entertain different opinions upon subjects which affect the whole country alike, such, for instance, as the principles upon which the government is to be conducted, then distinctions arise which may correctly be styled parties. Parties are a necessary evil in free governments; but they have not at all times the same character and the same propensities. At certain periods a nation may be oppressed by such insupportable evils as to conceive the design of effecting a total change in its political constitution; at other times the mischief lies still deeper, and the existence of society itself is endangered. Such are the times of great revolutions and of great parties. But between these epochs of misery and of confusion there are periods during which human society seems to rest, and mankind to make a pause. This pause is, indeed, only apparent, for time does not stop its course for nations any more than for men; they are all advancing towards a goal with which they are unacquainted; and we only imagine them to be stationary when their progress escapes our observation, as men who are going at a foot-pace seem to be standing still to those who run. But however this may be, there are certain epochs at which the changes that take place in the social and political constitution of nations are so slow and so insensible that men imagine their present condition to be a final state; and the human mind, believing itself to be firmly based upon certain foundations, does not extend its researches beyond the horizon which it descries. These are the times of small parties and of intrigue. The political parties which I style great are those which cling to principles more than to their consequences; to general, and not to especial cases; to ideas, and not to men. These parties are usually distinguished by a nobler character, by more generous passions, more genuine convictions, and a more bold and open conduct than the others. In them private interest, which always plays the chief part in political passions, is more studiously veiled under the pretext of the public good; and it may even be sometimes concealed from the eyes of the very persons whom it excites and impels.
