There we have the most important positive idea of eighteenth century speculation, standing forth detached and independent, no longer bound to a system. Fifty years before, no one would have dreamed of defining civilisation like that and counting on the immediate acquiescence of his audience. But progress has to be defined. It does not merely imply the improvement of social relations and public well-being. France in the seventeenth and eighteenth centuries was behind Holland and England in the sum and distribution of well-being among individuals, and yet she can claim that she was the most "civilised" country in those ages. The reason is that civilisation also implies the development of the individual life, of men's private faculties, sentiments, and ideas. The progress of man therefore includes both these developments. But they are intimately connected. We may observe how moral reformers generally recommend their proposals by promising social amelioration as a result, and that progressive politicians maintain that the progress of society necessarily induces moral improvement. The connection may not always be apparent, and at different times one or other kind of progress predominates. But one is followed by the other ultimately, though it may be after a long interval, for "la Providence a ses aises dans le temps." The rise of Christianity was one of the crises of civilisation, yet it did not in its early stages aim at any improvement of social conditions; it did not attack the great injustices which were wrought in the world. It meant a great crisis because it changed the beliefs and sentiments of individuals; social effects came afterwards. The civilisation of modern Europe has grown through a period of fifteen centuries and is still progressing. The rate of progress has been slower than that of Greek civilisation, but on the other hand it has been continuous, uninterrupted, and we can see "the vista of an immense career."
