THREE:For loading and unloading carts and waggons, the convenience of the old outside sling is well known; it is also a well-attested fact that accidents rarely happen with sling hoists, although they appear to be less safe than running platforms or lifts. As a general rule, the most dangerous machinery for handling or raising material is that which pretends to dispense with the care and vigilance of attendants, and the safest machinery that which enforces such attention. The condition which leads to danger in hoisting machinery is, that the power employed is opposed to the force of gravity, and as the force of gravity is acting continually, it is always ready to take advantage of the least cessation in the opposing force employed, and thus drag away the weight for which the two forces are contending; as a weight when under the influence of gravity is moved [65] at an accelerated velocity, if gravity becomes the master, the result is generally a serious accident. Lifting may be considered a case wherein the contrivances of man are brought to bear in overcoming or opposing a natural force; the imperfect force of the machinery is liable to accident or interruption, but gravity never fails to act. Acting on every piece of matter in proportion to its weight must be some force opposing and equal to that of gravity; for example, a piece of iron lying on a bench is opposed by the bench and held in resistance to gravity, and to move this piece of iron we have to substitute some opposing force, like that of the hands or lifting mechanism, to overcome gravity.

THREE:And he told us, on the beach, hed been here this morning, Sandy whispered to himself.Improvements, which have totally changed machine fitting during thirty years past, have been of a character to dispense in a great measure with hand skill, and supplant it with what may be termed mental skill. The mere physical effect produced by a man's hands has steadily diminished in value, until it has now almost come to be reckoned in foot-pounds; but the necessity [166] for practical knowledge instead of being diminished is increased.

THREE:It is generally assumed by the German critics that the atomic theory was peculiarly fitted to serve as a basis for the individualistic ethics of Epicureanism. To this we can hardly agree. The insignificance and powerlessness of the atoms, except when aggregated together in enormous numbers, would seem to be naturally more favourable to a system where the community went for everything and the individual for nothing; nor does the general acceptance of atomism by modern science seem to be accompanied by any relaxation of the social sentiment in its professors. Had the Stoics followed Democritus and Epicurus Heracleitusat least a conceivable hypothesissome equally cogent reason would doubtless have been forthcoming to indicate the appropriateness of their choice.161 As it is, we have no evidence that Epicurus saw anything more in the atomic theory than a convenient explanation of the world on purely mechanical principles.The relation of Spinozas Substance to its attributes is ambiguous. It is at once their cause, their totality, and their unity. The highly elastic and indefinite term Power helped these various aspects to play into and replace one another according to the requirements of the system. It is associated with the subjective possibility of multiplying imaginary existences to any amount; with the causal energy in which existence originates; and with the expansiveness characteristic alike of Extension and of Thought. For the two known attributes of the universal substance are not simply related to it as co-predicates of a common subject; they severally express its essential Power, and are, to that extent, identical with one another. But when we ask, How do they express Power? the same ambiguity recurs. Substance is revealed through its attributes, as a cause through its effects; as an aggregate through its constituents; and as an abstract notion through its concrete embodiments. Thus Extension and Thought are identical through their very differences, since these illustrate the versatility of their common source, and at the same time jointly contribute to the realisation of its perfection. But, for all practical purposes, Spinoza deals only with the parallelism and resemblance of the attributes. We have to see how he establishes it, and how far he was helped in so doing by the traditions of Greek philosophy.
