ONE:Of course we are speaking of causation as exercised under the conditions of time, space, matter, and motion. It is then identical with the transmission of energy and obeys the laws of energy. And to talk about causation under any other conditions than these is utter nonsense. But Plotinus and other philosophers exclude the most essential of the conditions specified from their enquiries into the ultimate origin of things. We are expressly informed that the genesis of Nous from the One, and of Soul from Nous, must not be conceived as taking place in time but in eternity.472 Unfortunately those who make such reservations are not consistent. They continue to talk about power, causation, priority, and so forth, as if these conceptions were separable from time. Hence they have to choose between making statements which are absolutely unintelligible and making statements which are absolutely untrue.When a tool is guided by turning on points, the movement is perfect, and the straightness or parallelism of holes bored in this manner is dependent only on the truth of the carriage movement. This plan of boring is employed for small steam cylinders, cylindrical valve seats, and in cases where accuracy is essential.
