We turn to the eighteenth century, and primarily to the school of thinkers called 'philosophes' in France, for the fullest and most enthusiastic statement of progress as a gospel. It is, of course, European, as all the greatest advances of thought have been; and German thinkers, as well as English, stand with the French in the vanguard. Kant and Herder, from different points of view, thought it out perhaps more thoroughly than any one else at that time; but the French believed in it as a nation and were willing to stake their lives and souls on the belief. Thus Turgot, before the Revolution, declared that 'the total mass of the human race marches continually though sometimes slowly towards an ever-increasing perfection'. And Condorcet, in the midst of the Revolution, while himself under its ban, painted a picture 'of the human race, freed from its chains, and marching with a firm tread on the road of truth and virtue and happiness'. Here is the gospel in its purest and simplest form, and when we are inclined to think that the crimes and the partial failure of the Revolution discredit its principles, it is well to remember that the man who believed in them most systematically, expounded his belief with perfect calmness and confidence as he lay under sentence of death from a revolutionary tribunal. If this enthusiasm is madness, we might all well wish to be possessed. The true line of criticism is different. At the Revolution, as before at the Renascence, the leaders of the new movement could not see all their debt to the past. Like the Renascence, they idealized certain features in classical antiquity, but they had not yet gained the notion of historical continuity; above all, they did not realize the value of the religious development of the Middle Ages. It was left for the nineteenth century and for us, its successors, to attempt the supreme task of seeing things steadily and seeing them whole.
