Nature and Second Nature

While the expression 'second nature' has no precise definition, at minimum, it connotes a transcendence of a 'nature' that is not necessarily incorporeal.  Now, in a pivotal passage in the Philosophy of Right, Hegel uses the term to characterize the relation of Will to Mind, i. e. the actualization of the freedom of the latter in the former.  So, Marx is plainly familiar with a concept of a Second Nature, and while he might not accept the implied characterization of incorporeal Mind as 'natural', there would be no such problem in adopting the contrast to Materialism.  So, the transcendence of 'nature' by voluntsry activity, in the German Ideology, and by a "power", in Trotsky's Their Morality and Ours, can be explained as a Second Nature, though the status of Dialectical Materialism in the immanent Dualism remains unclear, i. e. insofar as it precludes the exercise of Free Will, it, too, is transcended by the Second Nature.
