Solitude excites and strengthens the powers of the imagination to an uncommon degree, and thereby enfeebles the effect of the controlling powers of reason. The office of the latter faculty of the mind is, to examine with nice discernment and scrupulous attention, to compare the several properties of thoughts and things with each other, and to acquire, by cool and deliberate investigation, correct ideas of their combinations and effects. The exercise of their power suspends the vehemence of action, and abates the ardor of desire; but fancy performs her airy excursions upon light and vagrant wings, and flying around her objects without examination, embraces every pleasing image with increasing delight. Judgment separates and associates the ideas the mind has gained by sensation and reflection, and by determining their agreement or disagreement, searches after truth through the medium of probability; but the imagination employs itself in raising unsubstantial images, and portraying the form of things unknown in nature, and foreign to truth. It has, indeed, like memory, the power of reviving in the mind the ideas which, after having been imprinted there, have disappeared; but it differs from that faculty by altering, enlarging, diversifying, and frequently distorting, the subjects of its power. It bodies forth the form of things unknown, And gives to airy nothings A local habitation and a name. But the irregular and wild desires which seize upon the mind through the avenues of an untamed fancy and disordered imagination, are not exclusively the produce of solitude. The choice of wisdom or folly is offered to us in all places, and under every circumstance; but the mind of man is unhappily prone to that which is least worthy of it. I shall therefore endeavor to show, by some general observations, in what instances solitude is most likely to create those flights of imagination which mislead the mind, and corrupt the heart.
