What is there of an exciting nature in the common events of life and the usual course and uniformity of nature? Very little. However wondrous the works of the creation may be, habit has so accustomed us to behold them, that they are familiar to our eyes; they become matter of fact, and science has taught us to comprehend the nature of many phenomena, which might otherwise have appeared incredible: but when we seek for an unattainable object, however fallacious its attraction may be, the mind is roused to energetic action: if we strive to excel all others in the fine arts, in poetical productions, we become fired with an exalted zeal, which age and experience alone can temper. In our vain pursuit of ideal perfection, the mind may be compared to a focus in which our burning thoughts are concentrated, until we are consumed by disappointment: the love of Pygmalion was probably the most ardent passion that could fire the breast of man. Enthusiasm laughs to scorn the suggestion of the senses and common understanding, therefore all its priests and votaries are surrounded with a deceptive halo; and Plotinus maintained that a proper worship of the gods consisted in a mysterious self annihilation and a total extinction of every faculty. The same may be said of love, which, like all other enthusiastic passions, may be considered a temporary hallucination. Moreover the language of fiction is not required to maintain the self-evident testimonies of facts. As true as truth's simplicity, And simpler than the infancy of truth. Whereas false doctrines and fallacious opinions need all the aid of imagination's vivid colours to disguise their real form with a goodly outside. We may in general conclude that enthusiasts are at first deceived themselves to become in turn deceivers. Seldom does man display sufficient humility to admit that he has erred in his favourite doctrines, and how much less will he be disposed to confess his deviation from rectitude, when imposture becomes the source of wealth and power, and hypocrisy a trade: to the ghostly speculator we may well apply the lines of Massinger: Oh, now your hearts make ladders of your eyes, In show to climb to heaven, where your devotion Walks upon crutches. It is, however, fortunate that errors generally assist the development of truth. The progress of the Christian faith was materially forwarded by the absurdities and fallacies of all other religions; and Helvetius has truly observed that if we could for a moment doubt the truth of Christianity, its divine origin would be proved by its having survived the horrors of popery. False theories led Columbus to correct geographic conclusions, and Galileo's discoveries overthrew his own former theories. MEDICINAL EFFECTS OF WATER.
