Note 559 — Chapter XII · THE SPIRAL SHELLS OF THE FORAMINIFERA
Reading edition
The evolutionist theory, as Bergson puts it, “consists above all in establishing relations of ideal kinship, and in maintaining that wherever there is this relation of, so to speak, logical affiliation between forms, there is also a relation of chronological succession between the species in which these forms are materialised”: Creative Evolution, 1911, p. 26. Cf. supra, p. 251.
