In a later attempt to analyze the problem of development, Driesch examined it more fully from the point of view of the machine theory. This contribution must be looked upon rather as a _tour de force_ that is intended to show how far this idea can be carried in its application to development. Driesch explains that in his analytical theory he assumed from what is “given” in the egg that the egg can be understood causally, as a machine is understood, but what is “given” can be understood only teleologically. He says: “What I defended was not vitalism, but, so far as the phenomena of life are concerned, exactly the current physico-chemical dogmatism; but I did not fail to see and to point out the consequences of this dogmatism, which every one (except Lotze) has avoided, viz., that the adaptive basis in which the living phenomena take place is ‘given.’” Driesch defines his view as formal-teleological, in contrast to vitalistic. The former may also be called a machine theory of life in which the _purpose is given, not explained_. In later writings Driesch has thrown over some of his earlier conclusions and adopted a causal-vitalistic philosophy. The basis of this new conception is found in the proportional development of parts of an original whole, as has been explained in a preceding chapter. This result belongs to a category of phenomena that is in principle not machine-like, but of a specifically different kind. It is something that cannot be explained by the agencies of the outer world, such as light, gravity, salinity, temperature, etc. After examining other hypotheses, Driesch returns to a view that he had previously rejected, viz. the conception of “position,” by which is meant the influence of the location in the whole. This position has certain directions, but nothing in addition that is typical. By the term “location in the whole” is meant that the word “location” (_Lage_) shall refer not to geometric space, but to the organization of the object that has its own directions. A deformation of the whole may change very little the relative location of the parts.
