But as time passes and habituation to the exigencies of the machine techDology gains in range and consistency, the quasi-personal, handicraft conception of causation decays, — first and most notably in those material, inorganic sciences that stand in the closest relation to the mechanical technology, hut presently also in the organic sciences, and even in the moral sciences. The machine technology is a mechanical or material process, and requires the attention to be centred upon this process and the exigencies of the process. In such a process no one factor stands out as unequivocally the efficient cause in the case, whose personal char-

In this view there is, no doubt, a large and valuable element of truth. To the end of a mathematical (onnnlation o( causal phenomena as well as a tenacions grasp of the
