TWO:Plotinus, as we have said, starts with the Aristotelian account of Matter; but by a process of dialectical manipulation, he gradually brings it into almost complete agreement with Platos conception; thus, as usual, mediating between and combining the views of his two great authorities. In the first place, he takes advantage of Aristotles distinction between intelligible and sensible Matter, to strip the latter of that positive and vital significance with which it had been clothed in the Peripatetic system. In the world of Ideas, there is an element common to all specific forms, a fundamental unity in which they meet and inhere, which may without impropriety be called their Matter. But this Matter is an eternal and divine substance, inseparably united with the fixed forms which it supports, and, therefore, something which, equally with them, receives light and life and thought from the central source of being. It is otherwise with sensible Matter, the common substance of the corporeal elements. This is, to use the energetic expression of our philosopher, a decorated corpse.481 It does not remain constantly combined with any form, but is for ever passing from one to another, without manifesting a particular preference for any. As such, it is the absolute negation of Form, and can only be conceived, if at all, by326 thinking away every sensible quality. Neither has it any quantity, for quantity means magnitude, and magnitude implies definite figure. Aristotle opposed to each particular form a corresponding privation, and placed Matter midway between them. Plotinus, on the other hand, identifies Matter with the general privation of all forms. It is at this point that he begins to work his way back to the Platonic notion of Matter as simple extension. There must, after all, be something about Matter which enables it to receive every kind of quality and figure,it must have some sort of mass or bulk, not, indeed, in any definite sense, but with an equal capacity for expansion and for contraction. Now, says Plotinus, the very indeterminateness of Matter is precisely the capacity for extension in all directions that we require. Having no principle of stability, but being borne towards every form, and easily led about in all directions, it acquires the nature of a mass.482Machine motion is mainly rotary; and as rotary motion is accomplished by cylindrical parts such as shafts, bearings, pulleys and wheels, we find that the greater share of machine tools are directed to preparing cylindrical forms. If we note the area of the turned, bored and drilled surface in ordinary machinery, and compare with the amount of planed surface, we will find the former not less than as two to one in the finer class of machinery, and as three to one in the coarser class; from this may be estimated approximately the proportion of tools required for operating on cylindrical surfaces and plane surfaces; assuming the cutting tools to have the same capacity in the two cases, the proportion will be as three to one. This difference between the number of machines required for cylindrical and plane surfaces is farther increased, when we consider that tools act continually on cylindrical surfaces and intermittently on plane surfaces.

FORE:Nor was this all. Thought, after having, as it would seem, wandered away from reality in search of empty abstractions, by the help of those very abstractions regained possession of concrete existence, and acquired a far fuller intelligence of its complex manifestations. For, each individual character is an assemblage of qualities, and can only be understood when those qualities, after having been separately studied, are finally recombined. Thus, biography is a very late production of literature, and although biographies are the favourite reading of those who most despise philosophy, they could never have been written without its help. Moreover, before characters can be described they must exist. Now, it is partly philosophy which calls character into existence by sedulous inculcation of self-knowledge and self-culture, by consolidating a mans individuality into something independent of circumstances, so that it comes to form, not a figure in bas-relief, but what sculptors call a figure in the round. Such was Socrates himself, and such were the figures which he taught Xenophon and Plato to recognise and portray. Character-drawing begins with them, and the Memorabilia in particular is the earliest attempt at a biographical analysis that we possess. From this to Plutarchs Lives there was still a long journey to be accomplished, but the interval between them is less considerable than that which divides Xenophon from his immediate predecessor, Thucydides. And when we remember how intimately the substance of Christian teaching is connected with the literary form of its first record, we shall still better appreciate the all-penetrating influence of Hellenic thought,158 vying, as it does, with the forces of nature in subtlety and universal diffusion.

FORE:A remarkable strike had taken place in the Leo XIII Hospital. The head of this institution, Dr. Tits, also had been taken as a hostage. It was the most blackguardly act one can think of, to take away the man who had spent night and day mostly nursing wounded Germans. Dr. Noyons found it so harsh that he took counsel with the other doctors, and they decided not to resume work before Dr. Tits came back. This of course happened immediately.

FORE:But, towards the close of the sixteenth century, the time for amassing observations was past, no further progress being possible until the observations already recorded were interpreted aright. The just instinct of science perceived this; and for nearly a century after Cesalpino no addition of any magnitude was made to what Bacon called History, while mens conceptions of natural law were undergoing a radical transformation.544 To choose such a time for developing the Aristotelian philosophy was peculiarly unfortunate; for that philosophy had become, both on its good and on its bad side, an obstacle to progress, by encouraging studies which were not wanted, and by fostering a spirit of opposition to the Copernican astronomy.
