But Heraclitus totally fails to free himself from local conceptions. He speaks of the motion of the primordial principle in the upward and downward directions, in the higher and lower regions. He says that the chief accumulation thereof is above, and the chief deficiency below: and hence he regards the soul of a man as a portion of fire migrated from heaven. He carries his ideas of the transitory nature of all phenomena to their last consequences, and illustrates the noble doctrine that all which appears to us to be permanent is only a regulated and self-renewing concurrence of similar and opposite motions by such extravagances as that the sun is daily destroyed and renewed. [Sidenote: Physical and physiological doctrines of Heraclitus.] In the midst of many wild physical statements many true axioms are delivered. "All is ordered by reason and intelligence, though all is subject to Fate." Already he perceived what the metaphysicians of our own times are illustrating, that "man's mind can produce no certain knowledge from its own interior resources alone." He regarded the organs of sense as being the channels through which the outer life of the world, and therewith truth, enters into the mind, and that in sleep, when the organs of sense are closed, we are shut out from all communion with the surrounding universal spirit. In his view every thing is animated and insouled, but to different degrees, organic objects being most completely or perfectly so. His astronomy may be anticipated from what has been said respecting the sun, which he moreover regarded as being scarcely more than a foot in diameter, and, like all other celestial objects, a mere meteor. His moral system was altogether based upon the physical, the fundamental dogma being the excellence of fire. Thus he accounted for the imbecility of the drunkard by his having a moist soul, and drew the inference that a warm or dry soul is the wisest and best; with justifiable patriotism asserting that the noblest souls must belong to a climate that is dry, intending thereby to indicate that Greece is man's fittest and truest country. There can be no doubt that in Heraclitus there is a strong tendency to the doctrine of a soul of the world. If the divinity is undistinguishable from heat, whither can we go to escape its influences? And in the restless activity and incessant changes it produces in every thing within our reach, do we not recognize the tokens of the illimitable and unshackled?
