ONE:Machines may be defined in general terms as agents for converting, transmitting, and applying power, or motion and force, which constitute power. By machinery the natural forces are utilised, and directed to the performance of operations where human strength is insufficient, when natural force is cheaper, and when the rate of movement exceeds what the hands can perform. The term "agent" applied to machines conveys a true idea of their nature and functions.

THREE:So far, Aristotle regards the soul as a function, or energy, or perfection of the body, from which it can no more be separated than vision from the eye. It is otherwise with the part of mind which he calls Nous, or Reasonthe faculty which takes cognisance of abstract ideas or the pure forms of things. This corresponds, in the microcosm, to the eternal Nous of the macrocosm, and, like it, is absolutely immaterial, not depending for its activity on the exercise of any bodily organ. There is, however, a general analogy between sensation and thought considered as processes of cognition. Previous to experience, the Nous is no thought in particular, but merely a possibility of thinking, like a smooth wax tablet waiting to be written on. It is determined to some particular idea by contact with the objective forms of things, and in this determination is raised from power to actuality. The law of moderation, however, does not apply to thought. Excessive stimulation is first injurious and then destructive to the organs of sense, but we cannot have too much of an idea; the more intense it is the better are we able to conceive all the367 ideas that come under it, just because ideation is an incorporeal process. And there seems to be this further distinction between sensation and thought, that the latter is much more completely identified with its object than the former; it is in the very act of imprinting themselves on the Nous that the forms of things become perfectly detached from matter, and so attain their final realisation. It is only in our consciousness that the eternal ideas of transient phenomena become conscious of themselves. Such, we take it, is the true interpretation of Aristotles famous distinction between an active and a passive Nous. The one, he tells us, makes whatever the other is made. The active Nous is like light raising colours from possibility to actuality. It is eternal, but we have no remembrance of its past existence, because the passive Nous, without which it can think nothing, is perishable.That also was Sandys opinion when, after a rapid inspection, they agreed with Jeff that the amphibian, set down with only a strained tail skid and a burst tire in the landing wheel gear, was usable.
THREE:We have already repeatedly alluded to the only man of genius whom Epicureanism ever counted among its disciples. It is time that we should determine with more precision the actual relation in which he stood to the master whom, with a touching survival of religious sentiment, he revered as a saviour and a god.
THREE:We now enter on the last period of purely objective philosophy, an age of mediating and reconciling, but still profoundly original speculation. Its principal representatives, with whom alone we have to deal, are Empedocles, the Atomists, Leucippus and Democritus, and Anaxagoras. There is considerable doubt and difficulty respecting the order in which they should be placed. Anaxagoras was unquestionably the oldest and Democritus the youngest of the four, the difference between their ages being forty years. It is also nearly certain that the Atomists came after Empedocles. But if we take a celebrated expression of Aristotles21 literally (as there is no reason why it should not be taken),27 Anaxagoras, although born before Empedocles, published his views at a later period. Was he also anticipated by Leucippus? We cannot tell with certainty, but it seems likely from a comparison of their doctrines that he was; and in all cases the man who naturalised philosophy in Athens, and who by his theory of a creative reason furnishes a transition to the age of subjective speculation, will be most conveniently placed at the close of the pre-Socratic period.
