The preceding remarks are partly attempts at interpretation, and partly critical emendations of some of the concepts and opinions expressed by Marx and in the Marxian literature. But how many other points deserve to undergo revision! Beginning with that _concentration of private property in a few hands_, which threatens to become something like the discredited _iron law of wages_, and ending with that strange statement in the history of philosophy that _the labour movement is the heir of German classical philosophy_. And attention could thus be given to another group of questions which we have not discussed (_e.g._ to the conception of future society) in regard to their detailed elucidation and their practical and historical applications.[72] If that _decomposition of Marxism_, which some have predicted,[73] meant a careful critical revision, it would indeed be welcome. To sum up, in the meantime, the chief results which are suggested in the preceding remarks: they maintain. 1. In regard to economic science, the _justification_ of Marxian economics, understood not as general economic science, but as comparative sociological economics, which is concerned with a problem of primary interest for historical and social life. 2. In regard to the philosophy of history, the _purification_ of historical materialism from all traces of any _a priori_ standpoint (whether inherited from Hegelianism or an infection from ordinary evolutionism) and the understanding of the theory as a simple, albeit a fruitful, _canon_ of historical interpretation. 3. In regard to practical matters, the _impossibility of inferring_ the Marxian social programme (or, indeed, any other social programme) from the propositions of pure science, since the appraisement of social programmes must be a matter of empirical observations and practical convictions; in which connection the Marxian programme cannot but appear one of the noblest and boldest and also one of those which obtain most support from the objective conditions of existing society. 4. In regard to ethics, the _abandonment of the legend_ of the intrinsic _immorality_ or of the intrinsic _anti-ethical_ character of Marxism.
