J. B. Bury,
The Idea of Progress: An Inquiry into Its Origin and Growth
“ Civilisation has been organised here and there, now and then, up to a certain point; there have been eras of rapid progress, but how can we be sure that these are not episodes, themselves also fortuitous? For growth has been followed by decay, progress by regress; can it be said that history, authorises the conclusion that reason will ever gain such an ascendancy that the play of chance will no longer be able to thwart her will? Is such a conclusion more than a hope, unsanctioned by the data of past experience, merely one of the characteristics of the age of illumination? ”
