If I negate powdered wigs, I am still left with unpowdered wigs. - Karl Marx

Once the inner connection is grasped, all theoretical belief in the permanent necessity of existing conditions collapses before their collapse in practice — Letter to Ludwig Kugelmann (July 11, 1868)

These contradictions, of course, lead to explosions, crises, in which momentary suspension of all labour and annihilation of a great part of the capital violently lead it back to the point where it is enabled [to go on] fully employing its productive powers without committing suicide. Yet, these regularly recurring catastrophes lead to their repetition on a higher scale, and finally to its violent overthrow. There are moments in the developed movement of capital which delay this movement other than by crises; such as e.g. the constant devaluation of a part of the existing capital: the transformation of a great part of capital into fixed capital which does not serve as agency of direct production; unproductive waste of a great portion of capital etc.

It is impossible to pursue this nonsense any further.
