[109] In fact, it assumes the existence of two worlds, one good and one bad; the latter created by the evil power for the purpose of damaging the former. The existing cosmos is a mere mixture of the two, and the "last judgment" is a root-and-branch extirpation of the work of Ahriman. Note 12 (p. 69). There is no snare in which the feet of a modern student of ancient lore are more easily entangled, than that which is spread by the similarity of the language of antiquity to modern modes of expression. I do not presume to interpret the obscurest of Greek philosophers; all I wish is to point out, that his words, in the sense accepted by competent interpreters, fit modern ideas singularly well. So far as the general theory of evolution goes there is no difficulty. The aphorism about the river; the figure of the child playing on the shore; the kingship and fatherhood of strife, seem decisive. The [Greek phrase osod ano kato mie] expresses, with singular aptness, the cyclical aspect of the one process of organic evolution in individual plants and animals: yet it may be a question whether the Heracleitean strife included any distinct conception of the struggle for existence. Again, it is tempting to compare the part played by the Heracleitean "fire" with that ascribed by the moderns to heat, or rather to that cause of motion of which heat is one expression; and a little ingenuity might find a foreshadowing of the doctrine of the conservation of energy, in the saying [110] that all the things are changed into fire and fire into all things, as gold into goods and goods into gold. Note 13 (p. 71). Pope's lines in the Essay on Man(Ep. i. 267-8), All are but parts of one stupendous whole, Whose body Nature is, and God the soul," simply paraphrase Seneca's "quem in hoc mundo locum deus obtinet, hunc in homine animus: quod est illic materia, id nobis corpus est."--(Ep. lxv. 24); which again is a Latin version of the old Stoical doctrine, [Greek phrase eis apan tou kosou meros diekei o nous, kataper aph emon e psuche]. So far as the testimony for the universality of what ordinary people call "evil" goes, there is nothing better than the writings of the Stoics themselves. They might serve, as a storehouse for the epigrams of the ultra-pessimists. Heracleitus (circa 500 B.C.) says just as hard things about ordinary humanity as his disciples centuries later; and there really seems no need to seek for the causes of this dark view of life in the circumstances of the time of Alexander's successors or of the early Emperors of Rome. To the man with an ethical ideal, the world, including himself, will always seem full of evil. Note 14 (P. 73).
