Those who expected from Mr. Harrison an interesting rejoinder to my reply, will not be disappointed. Those who looked for points skilfully made, which either are, or seem to be, telling, will be fully satisfied. Those who sought pleasure from witnessing a display of literary power, will close his article gratified with the hour they have spent over it. Those only will be not altogether contented who supposed that my outspoken criticism of Mr. Harrison’s statements and views, would excite him to an unusual display of that trenchant style for which he is famous; since he has, for the most part, continued the discussion with calmness. After saying thus much it may seem that some apology is needed for continuing a controversy of which many, if not most, readers, have by this time become weary. But gladly as I would leave the matter where it stands, alike to save my own time and others’ attention, there are sundry motives which forbid me. Partly my excuse must be the profound importance and perennial interest of the questions raised. Partly I am prompted by the consideration that it is a pity to cease just when a few more pages will make clear sundry of the issues, and leave readers in a better position for deciding. Partly it seems to me wrong to leave grave misunderstandings unrectified. And partly I am reluctant on personal grounds to pass by some of Mr. Harrison’s statements unnoticed. One of these statements, indeed, it would be imperative on me to notice, since it reflects on me in a serious way. Speaking of the _Descriptive Sociology_, which contains a large part (though by no means all) of the evidence used in the _Principles of Sociology_, and referring to the compilers who, under my superintendence, selected the materials forming that work, Mr. Harrison says:— Of course these intelligent gentlemen had little difficulty in clipping from hundreds of books about foreign races sentences which seem to support Mr. Spencer’s doctrines. The whole proceeding is too much like that of a famous lawyer who wrote a law book, and then gave it to his pupils to find the “cases” which supported his law.
