_ 66 Cf._ Roux, “Archiv. fur Entwicklungsmechanik.” The name sufficiently indicates the scope. 67 For a discussion of the difficulties and impossibilities of this theory see page 148 above. 68 “Preformation oder Epigenesis?” Outlines of a theory of the development of organisms. Jena, 1894. (Part I. of “Zeit- und Streit-fragen der Biologie.”) Translated by P. Chalmers Mitchell, “The Biological Problem of To-day.” 69 In his earlier period. Later he rejects both preformation and epigenesis, as mechanical distortions of vital processes. 70 See also Lotze’s interesting article “Instinct” in the same work. 71 Part II. of his “Zeit- und Streit-fragen der Biologie.” 72 Second Edition, 1902. 73 In Vol. II. p. 139. 1898. 74 “General Physiology.” Translated by Lee. London. 1899. P. 170. 75 As a remarkable instance and corroboration of this, we may refer to the ever-recurring, instinctive antipathy of deeply religious temperaments, from Augustine to Luther and Schleiermacher, to the Aristotelian mood and its conception of the world, and their sympathy with Plato’s (mostly and especially in their “Platonised” expressions). The clear-cut, luminous, conception of the world which expresses everything in terms of commensurable concepts is thoroughly Aristotelian. But it would be difficult to find a place in it for the peculiar element which lies at the root of all true devotional feeling, and which makes faith something more than the highest “reverence, love and trust.” 76 “Arch. für pathol. Anatomie und Physiologie,” Bd. VIII. 1855. 77 Vol. IX., 1856. 78 The same is true even of crystals, “_omne crystallum e crystallo_.” _ 79 Cf._ “Ueber die Aufgabe der Naturwissenschaft,” Jena, 1876. “Naturwissenschaftliche Tatsachen und Probleme.” “Physiologie und Entwicklungslehre,” 1886, in the collection of the “Allgemeiner Vereins für Deutsche Literatur.” Also in the same collection, “Aus Natur- und Menschen-leben.”
