A debility and dimness of the imaginative power, and a consequent necessity of reliance on the immediate impressions of the senses, do, we know well, render the mind liable to superstition and fanaticism. Having a deficient portion of internal and proper warmth, minds of this class seek in the crowd circum fana for a warmth in common, which they do not possess singly. Cold and phlegmatic in their own nature, like damp hay, they heat and inflame by co-acervation; or like bees they become restless and irritable through the increased temperature of collected multitudes. Hence the German word for fanaticism, (such at least was its original import,) is derived from the swarming of bees, namely, schwaermen, schwaermerey. The passion being in an inverse proportion to the insight,--that the more vivid, as this the less distinct--anger is the inevitable consequence. The absense of all foundation within their own minds for that, which they yet believe both true and indispensable to their safety and happiness, cannot but produce an uneasy state of feeling, an involuntary sense of fear from which nature has no means of rescuing herself but by anger. Experience informs us that the first defence of weak minds is to recriminate. There’s no philosopher but sees, That rage and fear are one disease; Tho’ that may burn, and this may freeze, They’re both alike the ague. But where the ideas are vivid, and there exists an endless power of combining and modifying them, the feelings and affections blend more easily and intimately with these ideal creations than with the objects of the senses; the mind is affected by thoughts, rather than by things; and only then feels the requisite interest even for the most important events and accidents, when by means of meditation they have passed into thoughts. The sanity of the mind is between superstition with fanaticism on the one hand, and enthusiasm with indifference and a diseased slowness to action on the other. For the conceptions of the mind may be so vivid and adequate, as to preclude that impulse to the realizing of them, which is strongest and most restless in those, who possess more than mere talent, (or the faculty of appropriating and applying the knowledge of others,)--yet still want something of the creative and self-sufficing power of absolute genius. For this reason therefore, they are men of commanding genius. While the former rest content between thought and reality, as it were in an intermundium of which their own living spirit supplies the substance, and their imagination the ever-varying form; the latter must impress their preconceptions on the world without, in order to present them back to their own view with the satisfying degree of clearness, distinctness, and individuality. These in tranquil times are formed to exhibit a perfect poem in palace, or temple, or landscape-garden; or a tale of romance in canals that join
