And I will say yet more; in ethical matters, I have not yet succeeded in freeing myself from the prison of the Kantian Critique, and do not yet see the position taken up by Kant surpassed; on the contrary, I see it strengthened by some of the most modern tendencies, and to me the way in which Engels attacks Dühring with regard to the principles of morality in his well-known book, does not in truth appear very exhaustive.[70] Here again the procedure is repeated which we have already criticised in connection with the discussions upon the general concept of value. Where Dühring, owing to the exigencies of scientific abstraction, takes for consideration the isolated individual and explicitly states that he is dealing with an abstract illustration (_Denkschema_), Engels remarks, wittily but erroneously--that the isolated man is nothing but a new edition of the first Adam in the Garden of Eden. It is true that in that criticism are contained many well-directed blows; and it might even be called just, if it refers only to ethical conceptions in the sense of assemblages of special rules and moral judgments, relative to definite social situations, which assemblages and constructions cannot claim absolute truth for all times, and all places, precisely because they are always made for particular times and particular places. But apart from these special constructions, analysis offers us the essential and ruling principles of morality, which give opportunity for questions which may, truly, be differently answered, but which most certainly are not taken into account by Marx and Engels. And, in truth, even if some may be able to write on the _theory of knowledge according to_ _Marx_,[71] to write on the principles of ethics according to Marx seems to me a somewhat hopeless undertaking. VI CONCLUSION _Recapitulation: 1. Justification of Marxian economics as comparative sociological economics: 2. Historical materialism simply a canon of historical interpretation: 3. Marxian social programme not a pure science: 4. Marxism neither intrinsically moral nor antimoral._
