“The connected arrangement of the essays which their reissue permits brings into fuller relief Mr. Huxley’s masterly powers of exposition. Sweeping the subject-matter clear of all logomachies, he lets the light of common day fall upon it. He shows that the place of hypothesis in science, as the starting point of verification of the phenomena to be explained, is but an extension of the assumptions which underlie actions in everyday affairs; and that the method of scientific investigation is only the method which rules the ordinary business of life.”—London Chronicle.
