Since [Rousseau's] time, and largely thanks to him, the Ego has steadily tended to efface itself, and, for purposes of model, to become a manikin on which the toilet of education is to be draped in order to show the fit or misfit of the clothes. The object of study is the garment, not the figure. [...] The manikin, therefore, has the same value as any other geometrical figure of three or more dimensions, which is used for the study of relation. For that purpose it cannot be spared; it is the only measure of motion, of proportion, of human condition; it must have the air of reality; must be taken for real; must be treated as though it had life;—Who knows? Possibly it had! (7-8)
