The hour has come for us to commence our retro spect of one of the most wonderful sections of time that was ever measured by the sweep of the earth. Already the expert is at work dissecting out and studying his particular phase of that vast world of thought and action we call the nineteenth century. Art, literature, commerce, industry, politics, ethics all have their high interpreters among us; but in the chance of life it has fallen out that there is none to read aright for us, in historic retrospect, what after ages will probably regard as the most salient feature of the nineteenth century — the con?ict of theology with philosophy and science. The pens of our Huxleys, and Tyndalls, and Darwins lie where they fell there is none left in strength among us to sum up the issues of that struggle with knowledge and sympathy.
