We here see that before he was one-and-twenty years old, Greg was possessed by the conception that haunted him to the very end. When the people complain, their complaint savours of rebellion. Those who make themselves the mouthpieces of popular complaint must be wicked incendiaries. The privileged classes must be ordained by Nature to rule over the non-privileged. The few ought to direct and teach, the many to learn. That was Greg's theory of government from first to last. It was derived at this time, I suppose, from Burke, without the powerful correctives and indispensable supplements that are to be found in Burke's earlier writings. Some one said of De Tocqueville, who afterwards became Mr. Greg's friend, and who showed in a milder form the same fear of democracy, 'Il a commence a penser avant d'avoir rien appris; ce qui fait qu'il a quelquefois pense creux.' What is to be said for Mr. Greg, now and always, is that he most honourably accepted the obligations of his doctrine, and did his best to discharge his own duties as a member of the directing class. He did not escape moods of reaction. The truth seems to be, that though his life was always well filled, he inherited rather the easy and buoyant disposition of his father than the energy and strenuousness of his mother, though he too could be energetic and strenuous enough upon occasion. Both William Greg and his favourite brother were of what is called, with doubtful fitness, the feminine temperament. It was much less true of William than of Samuel Greg; but it was in some degree true of him also that, though firm, tenacious, and infinitely patient, 'he rather lacked that harder and tougher fibre, both of mind and frame, which makes the battle of life so easy and so successful to many men.' It may be suspected in both cases that their excessive and prolonged devotion to the practice of mesmerism and animal magnetism had tended to relax rather than to brace the natural fibre. Samuel Greg broke down at a comparatively early age; and though his brother's more vigorous system showed no evil results for many long years to come, there was a severe reaction from the nervous tension of their mesmeric experimentation. Those who trace despondent speculations of the mind to depressed or morbid conditions of body will find some support for their thesis in Mr. Greg's case. When he was only one-and-twenty he writes to his sister (December 2, 1830):--
