To that fact alone I try to ascribe the curious flood of thoughts that swept me in those midnight hours. Except for the heat, perhaps in a measure for the silence, I wouldn't have known them at all. I got to thinking about last night's crime, and I couldn't get it out of mind. The conceptions I had formed of it, the theories and decisions, seemed less and less convincing as I sat overlooking those shadowed, silent grounds. So much depends on the point of view. Ordinarily, our will gives us strength to believe wholly what we want to believe and nothing else. But the powers of the will were unstable to-night, the whole seat of being was shaken, and my fine theories in regard to Pescini seemed to lack the stuff of truth. I suppose every man present provided some satisfactory theory to fit the facts, for no other reason than that we didn't want to change our conception of Things as They Are. Such a course was essential to our own self-comfort and security. But my Pescini theory seemed far-fetched. In that silence and that heat, anything could be true at Kastle Krags!
From this point my mind led logically to the most disquieting and fearful thing of all. What was to prevent last night's crime from recurring?
It isn't hard to see the basis for such a thought. Some way, in these last, stifling, almost maddening hours, it had become difficult to rely implicitly on our rational interpretation of things. Certain things are credible to the every-day man in the every-day mood--things such as aeronautics and wireless, that to a savage mind would seem a thousand times more incredible than mere witchcraft and magic--and certain things simply can not and will not be believed. Society itself, our laws, our customs, our basic attitude towards life depends on a fine balance of what is credible and what is not, an imperious disbelief in any manifestation out of the common run of things. It is altogether good for society when this can be so. Men can not rise up from savagery until it is so. As long as black magic and witchcraft haunt the souls of men, there is nothing to trust, nothing to hold to or build towards, nothing permanent or infallible on which to rely, and hope can not escape from fear, and there is no promise that to-day's work will stand till to-morrow. Men are far happier when they may master their own beliefs. There is nothing so destructive to happiness, so favorable to the dominion of Fear, as an indiscriminate credulity. Those African explorers who have seen the curse of fear in the Congo tribes need not be told this fact.
