But the real difficulty appears when the necessity for exposition arises. If one undertakes to explain, if one has to condense and solidify for the purpose of teaching, if one wishes to make others understand, and share the knowledge one has attained, then indeed our difficulties commence. What seemed so grand and alluring to look at will not stand the ordinary handling of scientific language and logical statement as between man and man. The illusion vanishes, the system has gone. In these remarks we speak only of Mr. Spencer's cosmical system. Of the general value of this work as a philosopher we express no opinion. In the estimation of competent thinkers it is very great. Fiske, Youmans, Carveth Read, Ribot, Maudsley, Clifford, Sully, Grant Allen, Gopinay, and others are all working on Spencerian lines, but we do not understand that they accept the cosmical explanation of Mr. Spencer. He marks not the age of complete accomplishment but the age of transition. He has not grasped the solution of problems, but he has shewn the direction of future studies. He has failed in his grand endeavour, but he has shown what to aim at and has pointed the way. Much of his detailed work has been good and effective, and therefore one feels some compunction in writing of him so severely. Nevertheless a man of such eminence must not be held sacred from criticism, but on the contrary, just by reason of his eminence and consequent influence, must his work be well examined before it is accepted and approved. This is the task we have set ourselves and which may now be considered as complete. We have approached the study without any prepossessions, and we have endeavoured, while being very strict, to be perfectly fair and honest in our presentations of Mr. Spencer's theories. Naturally the work has been long and tedious, and where so many contradictory and indistinct expressions of opinion are given it has been necessary to deal largely in quotations. This has been done in justice both to ourselves and to our author. If we have succeeded in bringing out the main lines of thought for the future use of students we shall have accomplished our end. It is only by very strict thinking and discussion that truth is finally evolved.
