The historical process has created the preconditions, both material and intellectual, for the realisation of Reason (Hegel) in the organisation (Marx), for the convergence of freedom and necessity. However, freedom which converges with (or is even absorbed by) necessity is not the final form of freedom. At this ultimate point, Hegel and Marx again agree. The realm of true freedom is beyond the realm of necessity. Freedom as well as necessity is redefined. For Hegel, ultimate freedom resides in the realm of the Absolute Spirit. For Marx, the realm of necessity is to be mastered by a society whose reproduction has been subjected to the control of the individuals, and freedom is the free play of individual faculties outside the realm of necessary labour. Freedom is 'confined' to free time - but free time is, quantitatively and qualitatively, the very content of life.
