Theoretical mind is the attempt of the self-conscious person to take possession of the world through the exercise of the intellect, but Hegel argues that without the supplement of practical activity such a grasp cannot be achieved. In practical activity man transforms objects and once they are thus transformed by human activity, the products can be appropriated by the human intelligence. Full self-consciousness is achieved when the mind can fully elucidate its own relationship to the world in practical activity. This is a point of crucial importance. A conceptual grasp of an object can only be attained when that object has been formed and structured by human praxis…
Accordingly, full self-consciousness is achieved when man can have a full grasp of the kinds of transformations which he has effected through his practical activity on a world which is not the mere product of his mind, but which can be shaped by his will, this process at the same time contributing to his own development as a person.
