THREE:
FORE:Drawings are, in fact, the base of shop system, upon which depends not only the accuracy and uniformity of what is produced, but also, in a great degree, its cost. Complete drawings of whatever is made are now considered indispensable in the best regulated establishments; yet we are not so far removed from a time when most work was made without drawings, but what we may contrast the present system with that which existed but a few years ago, when to construct [76]a new machine was a great undertaking, involving generally many experiments and mistakes.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.482
FORE:"Indeed it is, sir. A good deal better looking than the other poor fellow, but directly I set eyes upon him I couldn't fail to see the likeness. And when he took off his gloves, and showed the big orange spots, I felt certain."35
FORE:Cutting processes may be divided into two classes: cylindrical cutting, as in turning, boring, and drilling, to produce circular forms; and plane cutting, as in planing, shaping, slotting and shearing, to produce plane or rectangular forms. Abrading or grinding processes may be applied to forms of any kind.So much only is established in the Physics. Further particulars are given in the twelfth book of the Metaphysics. There we learn that, all movement being from possibility to actuality, the source of movement must be a completely realised actualitypure form without any admixture of matter. But the highest form known to us in the ascending scale of organic life is the human soul, and the highest function of soul is reason. Reason then must be that which moves without being moved itself, drawing all things upwards and onwards by the love which its perfection inspires. The eternal, infinite, absolute actuality existing beyond the outermost starry sphere is God. Aristotle describes God as the thought which thinks itself and finds in the simple act of self-consciousness an everlasting happiness, wonderful if it always equals the best moments of our mortal life, more wonderful still if it surpasses them. There is only one supreme God, for plurality is due to an admixture of matter, and He is pure form. The rule of many is not good, as Homer says. Let there be one Lord.

TWO:We have now reached a point where Greek philosophy seems to have swung back into the position which it occupied three hundred years before, towards the close of the Peloponnesian War. The ground is again divided between naturalists and humanists, the one school offering an encyclopaedic training in physical science and exact philology, the other literary, sceptical, and limiting its attention to the more immediate interests of life; but both agreeing in the supreme importance of conduct, and differing chiefly as to whether its basis should or should not be sought in a knowledge of the external world. Materialism is again in the ascendant, to this extent at least, that no other theory is contemplated by the students of physical science; while the promise of a spiritualistic creed is to be found, if at all, in the school whose scepticism throws it back on the subjective sphere, the invisible and impalpable world of mind. The attitude of philosophy towards religion has, indeed, undergone a marked change; for the Stoic naturalists count themselves among the159 most strenuous supporters of beliefs and practices which their Sophistic predecessors had contemned, while the humanist criticism is cautiously guarded by at least an external conformity to established usage; but the Platonic doctrine of immortality has disappeared with the dogmatic spiritualism on which it rested; and faith in superior beings tends to dissociate itself from morality, or to become identified with a simple belief in the fixity of natural law.
