Undoubtedly a great deal here depends upon the question whether, and in what degree, our knowledge is limited. And here the Reply seems to be by no means in accord with Newton and with Butler. By its contempt for authority, the Reply seems to cut off from us all knowledge that is not at first hand; but then also it seems to assume an original and first hand knowledge of all possible kinds of things. I will take an instance, all the easier to deal with because it is outside the immediate sphere of controversy. In one of those pieces of fine writing with which the Reply abounds, it is determined _obiter_ by a backhanded stroke (N. A. R., p. 491) that Shakespeare is "by far the greatest of the human race." I do not feel entitled to assert that he is not; but how vast and complex a question is here determined for us in this airy manner! Has the writer of the Reply really weighed the force, and measured the sweep of his own words? Whether Shakespeare has or has not the primacy of genius over a very few other names which might be placed in competition with his, is a question which has not yet been determined by the general or deliberate judgment of lettered mankind. But behind it lies another question, inexpressibly difficult, except for the Reply, to solve. That question is, what is the relation of human genius to human greatness. Is genius the sole constitutive element of greatness, or with what other elements, and in what relations to them, is it combined? Is every man great in proportion to his genius? Was Goldsmith, or was Sheridan, or was Burns, or was Byron, or was Goethe, or was Napoleon, or was Alcibiades, no smaller, and was Johnson, or was Howard, or was Washington, or was Phocion, or Leonidas, no greater, than in proportion to his genius properly so-called? How are we to find a common measure, again, for different kinds of greatness; how weigh, for example, Dante against Julius Caesar? And I am speaking of greatness properly so called, not of goodness properly so called. We might seem to be dealing with a writer whose contempt for authority in general is fully balanced, perhaps outweighed, by his respect for one authority in particular.
