FORE:It is well for an apprentice to invent or demonstrate all that he canthe more the better; but as explained in a previous place, what is attempted should be according to some system, and with a proper object. Time spent groping in the dark after something of which no definite conception has been formed, or for any object not to fill an ascertained want, is generally time lost. To demonstrate or invent, one should begin methodically, like a bricklayer builds a wall, as he mortars and sets each brick, so should an engineer qualify, by careful study, each piece or movement that is added to a mechanical structure, so that when done, the result may be useful and enduring.Boring may be called internal turning, differing from external turning, because of the tools performing the cutting movement, and in the cut being made on concave instead of convex surfaces; otherwise there is a close analogy between the operations of turning and boring. Boring is to some extent performed on lathes, either with boring bars or by what is termed chuck-boring, in the latter the material is revolved and the tools are stationary.

FORE:All existence, according to Plotinus, proceeds from the One, which he also calls God. But God does not create the world by a conscious exercise of power; for, as we have seen, every form of consciousness is excluded from his definition.319 Neither does it proceed from him by emanation, for this would imply a diminution of his substance.469 It is produced by an overflow of his infinite power.470 Our philosopher tries to explain and defend this rather unintelligible mode of derivation by the analogy of physical substances and their actions. Light is constantly coming from the sun without any loss to the luminary itself.471 And all things are, in like manner, constantly communicating their proper virtue to others while remaining unaltered themselves. Here we have a good example of the close connexion between science and abstract speculation. People often talk as if metaphysics was something beyond the reach of verification. But some metaphysical theories admit, at any rate, of disproof, in so far as they are founded on false physical theories. Had Plotinus known that neither the sun nor anything else in Nature can produce force out of nothing, he would, very probably, have hesitated to credit the One with such a power.You wont make me believe Dick flew that-there crate, he declared.
