In one part or another of his mental field of vision each of us therefore is a mystic. From all the phenomena which he himself has not observed, everyone forms shadowy, unstable presentations. Nevertheless, it is easy to distinguish healthy men from those who deserve the designation of mystic. There is a sure sign for each. The healthy man is in a condition to obtain sharply-defined presentations from his own immediate perceptions, and to comprehend their real connection. The mystic, on the contrary, mixes his ambiguous, cloudy, half-formed liminal representations with his immediate perceptions, which are thereby disturbed and obscured. Even the most superstitious peasant has definite presentations of his field work, of the feeding of his cattle, and of looking after his landmark. He may believe in the weather-witch, because he does not know how the rain comes to pass, but he does not wait a moment for the angels to plough for him. He may have his field blessed, because the real conditions of the thriving or perishing of his seed are beyond his ken, but he will never so put his trust in supernatural favour as to omit sowing his grain. All the genuine mystic’s presentations, on the contrary, even those of daily experience, are permeated and overgrown with that which is incomprehensible, because it is without form. His want of attention makes him incapable of apprehending the real connecting links between the simplest and most obviously related phenomena, and leads him to deduce them from one or another of the hazy, intangible presentations wavering and wandering in his consciousness.
