In lieu of an abstract, here is a brief excerpt of the content:Kiyozawa Manshi’s Two Theories of Evolution and Their Western InspirationDennis PROOIIntroductionIf one solely were to confine the scope of one’s inquiry into the defining trait of a “Tokyo School of Philosophy” to the years immediately following the founding of Tokyo University in 1877, it would be hard to escape the conclusion that philosophy there at the time was determined almost entirely by the dominant intellectual wind blowing through its lecture halls, namely that of evolutionary theory. Katō Hiroyuki (1836–1916), president of the university from 1890 to 1893, was one of its staunchest advocates, doing much to foster the spread of ideas that would today be typified as “Social-Darwinian.”1 Inoue Enryō (1858–1919), undoubtedly the Meiji period’s most successful public philosopher, came to embrace many Spencerian ideas on evolution under the influence of Toyama Masakazu (1848–1900), a devout Spencerian, during his time as a student there (from 1881 to 1885).2 Ernest F. Fenollosa (1853–1908), an American philosopher who exerted great influence over the university’s young philosophical minds, was working on a synthesis of the Spencerian and Hegelian philosophical systems.3 He had been brought to Tokyo University by the Darwinian zoologist Edward S. Morse (1838–1925), who was himself instrumental in the spread of evolutionary ideas. This quick survey of Tokyo notables serves not only to establish the dominance of evolutionary theory, but also to show how in the context of late nineteenth-century Japan, “evolutionary theory” (shinkaron 進化論) is best understood as an umbrella term that could refer to a wide array of ideas—including, but certainly not limited to, Darwinian, Social-Darwinian, Spencerian, and Hegelian ones, or a mix of these—on the nature of (individual and social) change, development, and progress.Although the impact of 1859’s The Origin of Species made Darwin a figure impossible to ignore, by no means was evolutionary theory [End Page 77] equated with his theory of natural selection. For their ideas of evolution, many looked to Herbert Spencer (1820–1903), regarded by the Victorian English as the philosopher of evolution and whose system of synthetic philosophy presented positivist-leaning Meiji-era Japanese intellectuals with a definitive model of philosophical achievement. Spencer prided himself in having been the first to formulate the principle of evolution, remarking in the revised version of Social Statics (1892) that he had arrived at the general idea as early as 1850, many years before The Origin of Species had appeared in print.4 From Spencer’s point of view, Darwin had done no more than confirm a posteriori for biological organisms what was in fact an a priori law of evolution, established by Spencer in First Principles (1867) both inductively and deductively as the universal tendency of phenomena to pass from “an indefinite, incoherent homogeneity to a definite, coherent heterogeneity,” a process accompanied by “an integration of matter and concomitant dissipation of motion.”5 Spencer’s nod to the materialist tradition by formulating his conception of evolution in terms of matter in motion in his own self-understanding placed him in the camp of English philosophy, which did not let itself be deluded by the wrong use of language and spurned the invocation of what from its perspective was superfluous metaphysics. The opposing camp of German philosophy—following William Hamilton (1788–1856), derided by Spencer as “absolute theorisers”—made abundant use of such metaphysics to defend a teleological understanding of evolution—the kind of understanding Darwin (with his emphasis on the non-teleological character of natural selection) and Spencer (with his focus on matter in motion) attempted to render obsolete.6Under the influence of Fenollosa, many students of philosophy at Tokyo University became attracted to the alternative German teleological model of evolution, the history of which via the German Romantics goes back to Leibniz’s attempt to reintroduce into physics the idea of final causes after these in that domain had been eliminated by Descartes.7 Descartes, to begin with, was the one to revolutionize natural philosophy by reducing the physical world to one of matter in motion ruled by efficient causation, imagining, much like Spencer two centuries later, that such a minimalist view of...
