"We cannot but think that Mr. Mill in this, his first work in pure metaphysics, has disappointed just expectation. In leaving the fields of practical philosophy, he seems to have left his genius behind him. Even the peculiar "cunning of his right hand"--even his unexcelled logical power avails him little, so continually does he fail to see distinctly the conception with which he is fencing.... As long as he is applying given principles to the solution of practical questions; as long as he has to do with the process of an argument, he proves himself a most able instructor and guide. But when he has to grapple with a metaphysical problem, it almost invariably arrives that the central, the metaphysical difficulty, escapes him."--(Pp. 78-80.)
