FORE:The De Rerum Natura is the greatest of Roman poems, because it is just the one work where the abstract genius of Rome met with a subject combining an abstract form with the interest and inspiration of concrete reality; where negation works with a greater power than assertion; where the satire is directed against follies more wide-spread and enduring than any others; where the teaching in some most essential points can never be superseded; and where dependence on a Greek model left the poet free to contribute from his own imagination those elements to which the poetic value of his work is entirely due. By a curious coincidence, the great poet of mediaeval Italy attained success by the employment of a somewhat similar method. Dante represented, it is true, in their victorious combination, three influences against which Lucretius waged an unrelenting warfarereligion, the idealising love of woman, and the spiritualistic philosophy of Greece. Nevertheless, they resemble each other in this important particular, that both have taken an114 abstract theory of the world as the mould into which the burning metal of their imaginative conceptions is poured. Dante, however, had a power of individual presentation which Lucretius either lacked or had no opportunity of exercising; and therefore he approaches nearer to that supreme creativeness which only two races, the Greek and the English, have hitherto displayed on a very extended scale.
FORE:Modern agnosticism occupies the same position with regard to the present foundation and possible future extension of human knowledge as was occupied by the ancient Sceptics with regard to the possibility of all knowledge. Its conclusions also are based on a very insufficient experience of what can be effected by experience, and on an analysis of cognition largely adopted from the system which it seeks to overthrow. Like Scepticism also, when logically thought out, it tends to issue in a self-contradiction, at one time affirming the consciousness of what is, by definition, beyond consciousness; and at another time dogmatically determining the points on which we must remain for ever ignorant. It may be that some problems, as stated by modern thinkers, are insoluble; but perhaps we may find our way our of them by transforming the question to be solved.Reciprocating tools are divided into those wherein the cutting movement is given to the tools, as in shaping and slotting machines, and machines wherein the cutting movement is given to the material to be planed, as in a common planing machine. Very strangely we find in general practice that machine tools for both the heaviest and the lightest class of work, such as shaping, and butting, operate upon the first principle, while pieces of a medium size are generally planed by being moved in contact with stationary tools.
