The development of psychologic research in our day has proved beyond a doubt that individuals of a certain disposition may be conscious of events actually occurring, or which have recently occurred, at a great distance; but it has not shown satisfactorily that things yet to happen are foreshadowed by that restless condition of the sensibilities which we call presentiment. We may, and perhaps must, admit that all that is or has been produces a real and perceptible impression upon all else that is. But there is as yet no good reason for believing that an impression of what shall be can be conveyed by anticipation—without reasoning—to the mind of man.
But though the realisation of a presentiment may be as doubtful as any event depending upon chance alone, yet the immense influence which a mere presentiment may exercise is too well known to be denied. The human intelligence has a strong tendency to believe in its own reasonings, of which, indeed, the results are often more accurate and reliable than those reached by the physical perceptions alone. The problems which can be correctly solved by inspection are few indeed compared with those which fall within the province of logic. Man trusts to his reason, and then often confounds the impressions produced by his passions with the results gained by semi-conscious deduction. His love, his hate, his anger create fears, and these supply him with presentiments which he is inclined to accept as so many well-reasoned grounds of action. If he is often deceived, he becomes aware of his mistake, and, going to the other extreme, considers a presentiment as a sort of warning that the contrary of what he expects will take place; if he chances to be often right he grows superstitious.
