This does not define the principle of either. If we are to state with entire accuracy the Reason-Principles of the Forms in Matter and associated with Matter, we cannot pass over the generative Reason-Principle, in this case that of Man, especially since we hold that a complete definition must cover the essential manner of being.
What, then, is this essential of Man? What is the indwelling, inseparable something which constitutes Man as here? Is the Reason-Principle itself a reasoning living being or merely a maker of that reasoning life-form? and what is it apart from that act of making?
The living being corresponds to a reasoning life in the Reason-Principle; man therefore is a reasoning life: but there is no life without soul; either, then, the soul supplies the reasoning life — and man therefore is not an essence but simply an activity of the soul — or the soul is the man.
But if reasoning soul is the man, why does it not constitute man upon its entry into some other animal form?
