For it might be urged that the validity of the sciences depends on on the validity of the processes of' realisation'; hence to base the validity of ' realisation' on the assumed validity of the sciences is to beg the question. Prof. Eulpe'a procedure, however, appears to be quite valid. The anti-realist arguments which he is concerned to refute are all, or nearly all, based oh the ground that' realisation' involves assumptions which are inconsistent with the methods and ideals of soience.

... of. Eulpe rightly maintains that the methods and ideals of science are best studied by observing the actual methods and aims pursued in actual scientific investigation; and any theory that would render the sciences themselves invalid has no claim to be called scientific, or to speak with the authority of science. A realist reviewer is not likely to find much cause for complaint in Prof. Eulpe's searching criticisms of anti-realist standpoints. At the same time it should be noted that he has not yet explained the precise character of his realist philosophy. ' Bealism' may cover a multitude of things, as is evident from the fact that Prof. Eulpe brings together under that designation the views of Bradley, Ladd, and the signatories to the American "Program and First Platform of Six Bealists". Even the term 'Critical Bealism' is not muoh more elucidating, since it only excludes naive realism. However, the volnme before us contains some indications that Prof. Eulpe's Critical Realism will probably not be on the lines of the ' New Bealism' expounded by English writers in recent years. Indeed, Prof. Eulpe does not appear to be acquainted with the F.ngliHh movement; though it is possible that he is reserving his views of English Bealism for later on when he comes to consider the last two questions on his programme. In any case, we are looking forward with great interest to the appearance of the remaining volumes of Die Realisierung, the first instalment of which is certainly full of good things. A. WOLF.
