less developed concrete entity may have been realized without entering into the manifold relations and bearings which are mentally expressed in the concrete category; but when the concrete entity attains fuller development it will retain the same category as a subordinate relation.
Money may exist and actually had existed in history before capital, or banks, or wage-labor came into existence. With that in mind, it may be said that the more simple category can serve as an expression of the predominant relations of an undeveloped whole or of the subordinate relations of a more developed whole, [relations] which had historically existed before the whole developed in the direction expressed in the more concrete category. In so far, the laws of abstract reasoning which ascends from the most simple to the complex, correspond to the actual process of history.
On the other hand, it may be said that there are highly developed but historically unripe forms of society in which the highest economic forms are to be found, such as co-operation, advanced division of labor, etc., and yet there is no money in existence, e. g. Peru.
