In this way, it may be conceived, modern science comes into the field under the cloak of technology and gradually encroaches on the domain of authentic theory previously held by other, higher, nobler, more profound, more spiritual, more intangible conceptions and systems of knowledge. In this early phase of modern science its central norm and universal solvent is the concept of workmanlike initiative and efficiency. This is the new organon. Whatever is to be explained must be reduced to this notation and explained in these terms; otherwise the inquiry does not come to rest. But when the requirements of this notation in terms of workmanship have been duly fulfilled the inquiry does come to rest. By the early decades of the nineteenth century, with a passable degree of thoroughness, other grounds of validity and other interpretations of phenomena, other vouchers for truth and reality, had been eliminated from the quest of authentic knowledge and from the terms in which theoretical results were conceived or expressed. The new organon had made good its pretensions. In this movement to establish the hegemony of workmanlike efficiency--under the style and title of the "law of causation," or of "efficient cause"--in the realm of knowledge, the English-speaking communities took the lead after the earlier scientific onset of the south-European communities had gone up in the smoke of war, politics and religion during the great era of state-making. The ground of this British lead in science is apparently the same as that of the British lead in technology which came to a head in the Industrial Revolution; and these two associated episodes of European civilisation are apparently both traceable to the relatively peaceable run of life, and so of habituation, in the English-speaking communities, as contrasted with the communities of the continent.[3]
