The circumstances under which John Stuart Mill wrote his Liberty are largely connected with the influence which Mrs. Taylor wielded over his career. The dedication is well known. It contains the most extraordinary panegyric on a woman that any philosopher has ever penned. "Were I but capable of interpreting to the world one-half the great thoughts and noble feelings which are buried in her grave, I should be the medium of a greater benefit to it than is ever likely to arise from anything that I can write, unprompted and unassisted by her all but unrivalled wisdom." It is easy for the ordinary worldly cynicism to curl a sceptical lip over sentences like these. There may be exaggeration of sentiment, the necessary and inevitable reaction of a man who was trained according to the "dry light" of so unimpressionable a man as James Mill, the father; but the passage quoted is not the only one in which John Stuart Mill proclaims his unhesitating belief in the intellectual influence of his wife.
