Imanishi Kinji, the founder of Japanese primatology, anthropologist,
ecologist, alpinist, and explorer, devoted his life to quest for the structure
and function of this world, including human beings. The influence of
Nishida Kitarō’s thought can be clearly read in his work. Imanishi wrote
“The World of Living Things” in 1941, during the Second World War, and
stated that since all organisms were originally differentiated from one
another, they must have the ability to recognize each other, and that is
why they can recognize each other and coexist even after differentiation
into many species. However, there must be a “place where mutual
recognition occurs.” This idea was derived from the phenomenon of
“segregation,” which Imanishi discovered through his observation of
mayflies. These ideas of “acceptance,” “segregation,” and “coexistence” are
in tension to Darwin’s evolutionary theory of “competition,” “adaptation,”
and “selection.” Darwin believed that the environment is a one-way
influence on organisms, and that selection functions by allowing
individuals of each species to adapt to the environment in which they live.
Imanishi, however, saw organisms and the environment as one and the
same, each affecting the other. In fact, the influence of Nishida can be
seen in this idea. In “Logic and Life,” published in 1937, Nishida stated,
“Life changes the environment, and the environment changes life.” This
is also a concept that is shared by von Uexküll’s “Umwelt” and Watsuji
Tetsurō’s “Fūdō (Milieu)” of the same period. Both Nishida and Imanishi
regarded “the structure as function, and the function as structure” as the
fundamental principle of life, and Imanishi called the state in which
individuals of the same species recognize each other and coexist spatially
and temporally a “society.” This was Imanishi’s practice of trying to prove
Nishida’s idea through nature observation, and through the results of
primatology, it is now common knowledge around the world that animals
have societies. Augustin Berque refers to the ideas of Nishida, Watsuji,
and Imanishi as predicative, not as a logic of substance and sees them as a
necessary alternative to Western excluded middle and dualism for the
present era, in the vein of the Oriental biassertion. The objective
remaking of the environment by modern science and technology to suit human convenience, we are now plagued by rapid climate and
environmental changes that exceed the limits of the earth. The “natural
study (not science)” that Imanishi conceived in his later years is a way of
thinking that does not divide nature into elements but considers the
whole as a flow, as a principle rather than as a phenomenon. Imanishi
spent his entire life exploring the issues of “proto-identity” as a human
organism. This problem originated in the philosophy of Nishida Kitarō
and has emerged as a problem of the Anthropocene through Imanishi’s
vast explorations of nature in his academic expeditions.
