The life of a nation thus flows in a regular sequence, determined by invariable law, and hence, in estimating different nations, we must not be deceived by the casual aspect they present. The philosophical comparison is made by considering their entire manner of career or cycle of progress, and not their momentary or transitory state. Though they may encounter disaster, their absolute course can never be retrograde; it is always onward, even if tending to dissolution. It is as with the individual, who is equally advancing in infancy, in maturity, in old age. Pascal was more than justified in his assertion that "the entire succession of men, through the whole course of ages, must be regarded as one man, always living and incessantly learning." In both cases, the manner of advance, though it may sometimes be unexpected, can never be abrupt. At each stage events and ideas emerge which not only necessarily owe their origin to preceding events and ideas, but extend far into the future and influence it. As these are crowded together, or occur more widely apart, national life, like individual, shows a variable rapidity, depending upon the intensity of thought and action. But, no matter how great that energy may be, or with what rapidity modifications may take place--since events are emerging as consequences of preceding events, and ideas from preceding ideas--in the midst of the most violent intellectual oscillations, a discerning observer will never fail to detect that there exists a law of continuous variation of human opinions. [Sidenote: Plan of this work.] [Sidenote: Selection among European communities.] In the examination of the progress of Europe on which we now enter, it is, of course, to intellectual phenomena that we must, for the most part, refer; material aggrandisement and political power offering us less important though still valuable indications, and serving our purpose rather in a corroborative way. There are five intellectual manifestations to which we may resort--philosophy, science, literature, religion, government. Our obvious course is, first, to study the progress of that member of the European family, the eldest in point of advancement, and to endeavour to ascertain the characteristics of its mental unfolding. We may reasonably expect that the younger members of the family, more or less distinctly, will offer us illustrations of the same mode of advancement that we shall thus find for Greece; and that the whole continent, which is the sum of these different parts, will, in its secular progress, comport itself in like manner. [Sidenote: Our investigation limited to the intellectual, and commencing with Greece.] [Sidenote: From thence we pass to the examination of all Europe.]
