A solemn air, and the best comforter To an unsettled fancy, cure thy brains Now useless, boiled within thy skull. Again; The charm dissolves apace, And, as the morning steals upon the night, Melting the darkness, so their rising senses Begin to chase the ignorant fumes that mantle Their clearer reason. Their understanding Begins to swell: and the approaching tide Will shortly fill the reasonable shores That now lie foul and muddy. The perception of real affinities between events, (that is to say, of _ideal_ affinities, for those only are real,) enables the poet thus to make free with the most imposing forms and phenomena of the world, and to assert the predominance of the soul. 3. Whilst thus the poet animates nature with his own thoughts, he differs from the philosopher only herein, that the one proposes Beauty as his main end; the other Truth. But the philosopher, not less than the poet, postpones the apparent order and relations of things to the empire of thought. "The problem of philosophy," according to Plato, "is, for all that exists conditionally, to find a ground unconditioned and absolute." It proceeds on the faith that a law determines all phenomena, which being known, the phenomena can be predicted. That law, when in the mind, is an idea. Its beauty is infinite. The true philosopher and the true poet are one, and a beauty, which is truth, and a truth, which is beauty, is the aim of both. Is not the charm of one of Plato's or Aristotle's definitions, strictly like that of the Antigone of Sophocles? It is, in both cases, that a spiritual life has been imparted to nature; that the solid seeming block of matter has been pervaded and dissolved by a thought; that this feeble human being has penetrated the vast masses of nature with an informing soul, and recognised itself in their harmony, that is, seized their law. In physics, when this is attained, the memory disburthens itself of its cumbrous catalogues of particulars, and carries centuries of observation in a single formula. Thus even in physics, the material is degraded before the spiritual. The astronomer, the geometer, rely on their irrefragable analysis, and disdain the results of observation. The sublime remark of Euler on his law of arches, "This will be found contrary to all experience, yet is true;" had already transferred nature into the mind, and left matter like an outcast corpse.
