9. We admit, then, a Necessity in all that is brought about by this compromise between evil and accidental circumstance: what room was there for anything else than the thing that is? Given all the causes, all must happen beyond aye or nay- that is, all the external and whatever may be due to the sidereal circuit- therefore when the Soul has been modified by outer forces and acts under that pressure so that what it does is no more than an unreflecting acceptance of stimulus, neither the act nor the state can be described as voluntary: so, too, when even from within itself, it falls at times below its best and ignores the true, the highest, laws of action.
But when our Soul holds to its Reason-Principle, to the guide, pure and detached and native to itself, only then can we speak of personal operation, of voluntary act. Things so done may truly be described as our doing, for they have no other source; they are the issue of the unmingled Soul, a Principle that is a First, a leader, a sovereign not subject to the errors of ignorance, not to be overthrown by the tyranny of the desires which, where they can break in, drive and drag, so as to allow of no act of ours, but mere answer to stimulus.
