even out of their relation to the system, as affording the only argument by which the materiality of the mind can be disproved, and its immateriality put upon a right and intelligible footing.
The ninth contradiction which it corrects.15. The ninth contradiction which the system corrects is found in the assertion that the ego or mind is knowable per se, or in a state of pure indetermination. Proposition IX. gives expression to the true doctrine on this point
