Yet I am not more sure that ...

Yet I am not more sure that my soul lives, than I am that perverseness is one of the primitive impulses of the human heart - one of the indivisible primary faculties, or sentiments, which give direction to the character of Man. Who has not, a hundred times, found himself committing a vile or a silly action, for no other reason than because he knows he should not? Have we not a perpetual inclination, in the teeth of our best judgment, to violate that which is Law, merely because we understand it to be such?

I must perish in this deplorable folly. Thus, thus, and not otherwise, shall I be lost. I dread the events of the future, not in themselves, but in their results. I shudder at the thought of any, even the most trivial, incident, which may operate upon this intolerable agitation of soul. I have, indeed, no abhorrence of danger, except in its absolute effect-in terror. In this unnerved-in this pitiable condition-I feel that the period will sooner or later arrive when I must abandon life and reason together, in some struggle with the grim phantasm, FEAR.

It is the curse of a certain order of mind, that it can never rest satisfied with the consciousness of its ability to do a thing.Still less is it content with doing it. It must both know and show how it was done.
