Ignorance of inductive philosophy has given rise to many superstitions. By the means of inductive philosophy, we are enabled to trace effects to their true causes. For example: Lights have frequently been seen dancing over marshy grounds, near tan-yards, and burying-places, and along the sea shore. Credulous people have believed them to be the spirits of the uneasy dead. This belief must be considered superstitious, not having any foundation on rational evidence. Philosophy teaches that these lights are occasioned by an inflammable gas, which arises from decayed animal and vegetable substances, and takes fire on coming in contact with atmospheric air. Thus we may trace all effects to their true causes.
Many persons have supposed that pork killed in the increase of the moon would swell in boiling, while that killed in her wane would shrink. This opinion probably originated in the following manner: Some person killed, at different periods of the moon, two hogs which had been born and fattened together. That killed in her increase swelled in boiling; while the other, killed in her wane, shrunk. He could conceive of no way to account for the facts but on the supposition of lunar influence. This conclusion was accordingly adopted, and at length became an established truth. Yet there was no philosophy in forming this opinion from a few such facts. More experiments should have been tried; and they results would have shown that the real cause of the swelling and shrinking existed in the constitution of the animals. It would have been discovered that pork of fine and solid texture would commonly swell, whenever killed; while that of loose and coarse grain would as generally shrink. And the person would no more have thought of attributing the difference in his pork to the moon than to the spirit of Bonaparte.
Let this philosophic principle be applied to this whole class of superstitions, and we shall arrive at similar results. There is the supposed influence of the moon on making soap, grafting trees, cutting timber, and also upon the fortunes of love-sick swains and maidens. The latter are directed to go out in the evening and stand over the bars of a gate, and, looking on the moon, repeat the following lines:—
"All hail to the moon! all hail to thee!
I pray thee, good moon, reveal to me,
This night, who my husband shall be."
They must then go directly to bed, and will dream of their future husband. Upon trial of the experiment, they will probably be inclined to consider it a dreamy notion altogether; for love is of too serious a nature to be fed upon mere moonshine.
CHAPTER III.
IGNORANCE OF THE CAUSES OF DREAMS.
Ignorance of the causes of our dreams has given rise to many superstitions. Ancient divines have told us that some of our dreams proceed from ourselves, others from the Deity, and others again from the devil. We know, to be sure, from experience, that dreams proceed from ourselves in some, if not in all cases. We admit, however, that God has spoken to some of his dependent creatures by dreams; for we learn this from the Holy Scriptures. But such dreams were direct revelations for the accomplishment of some divine purpose. The volume of revelation was long since closed, and all that is essential to the present and eternal happiness of mankind is plainly revealed. There is therefore no necessity for any further communications from Heaven; and the gospel does not authorize us to expect any. Dreams may sometimes strike a conviction upon the mind, which our waking thoughts may fail to do. And they may sometimes have the appearance of being fulfilled; and yet there may be no necessity of supposing that God has made us the special organ of divine communications. Our dreams, in such cases, may be explained upon the principles of mental philosophy, without resorting to the miraculous interposition of Deity for an explanation.
To say that the devil is the author of all our disagreeable dreams that happen generally when we are in some trouble of body, mind, or estate, is too absurd to believe. And it is specially unbecoming the followers of Jesus to harbor an opinion so unbecoming in itself, so pernicious in its consequences, and so derogatory to the supreme Ruler of the universe. The true doctrine is, that our dreams originate from ourselves. Some are influenced by our bodily sensations. A person with a bottle of hot water at his feet dreams of ascending Ætna; and he finds the heat of the ground almost insupportable. Another kicks the bed clothes from his feet, and dreams of walking through snow banks, even in the summer season. Some dreams are influenced by the state of our stomach and bowels. The hungry prisoner dreams of well-furnished tables and the pleasures of eating. The glutton dreams of a surfeit and its attendant unpleasant sensations. Some dreams are influenced by our dispositions. The person of amiable temper and cheerful spirits is frequently refreshed with delightful scenes and visions of bliss; while those of morose, gloomy, irritable, and melancholy habits are generally harassed with those of a disagreeable and oppressive character. Some dreams are influenced by the state of our health. Sickness is usually productive of those of an unpleasant nature; while health secures those of an opposite description. A gentleman, mentioned by Locke, was not sensible of dreaming till he had a fever, at the age of twenty-six or seven. Some dreams are influenced by our waking thoughts. The mathematician solves difficult problems. The poet roves in Elysian groves. The miser makes great bargains. The sensualist riots in the haunts of dissipation. The criminal sees the dungeon or the gallows. The awakened sinner beholds the flames of hell, or looks upon the sceptre of pardon; and the Christian anticipates heavenly joy.
