Another note on how crises arise from the fundamental conditions of the capitalist social form. From what I recall Heinrich identifies the following in his introduction to capital and his comments on the crisis:
The general, abstract possibility of crisis denotes no more than the most abstract form of crisis, without content, without a compelling motivating factor. Sale and purchase may fall apart. They thus represent crisis potentia and their coincidence always remains a critical factor for the commodity. The transition from one to the other may, however, proceed smoothly. The most abstract form of crisis (and therefore the formal possibility of crisis) is thus the metamorphosis of the commodity itself; the contradiction of exchange value and use value, and furthermore of money and commodity, comprised within the unity of the commodity, exists in metamorphosis only as an involved movement. The factors which turn this possibility of crisis into [an actual] crisis are not contained in this form itself; it only implies that the framework for a crisis exists. Page mecw 32. 140
