"No sin is committed merely because a thought enters the mind, provided it is not made welcome. Perhaps we may use the figure that the thought first passes into an anteroom, where it stands before the mind acting as a judge. No matter how sordid or evil, it has not touched the personality with its infamy nor in any way laid guilt upon the soul unless and until the mind acting as judge admits it with a welcome. If the mind decides against it and dismisses it, the personality is not only unsullied but is, on the contrary, by this act of rejection stimulated and strengthened in moral power."
