THREE:The sudden and varied resistance to line shafts tends to loosen couplings, destroy gearing, and produce sudden strains that are unknown in other cases; and shafting arranged with the usual proportions for transmitting power will soon fail if applied to driving trip-hammers. Rigid connections or metal attachments ace impracticable, and a slipping belt arranged so as to have the tension varied at will is the usual and almost the only successful means of transmitting power to hammers. The motion of trip-hammers is a curious problem; a head and die weighing, together with the irons for attaching them, one hundred pounds, will, with a helve eight feet long, strike from two to three hundred blows a minute. This speed exceeds anything that could be attained by a direct reciprocal motion given to the hammer-head by a crank, and far exceeds any rate of speed that would be assumed from theoretical inference. The hammer-helve being of wood, is elastic, and acts like a vibrating spring, its vibrations keeping in unison with the speed of the tripping points. The whole machine, in fact, must be constructed upon a principle of elasticity throughout, and in this regard stands as an exception to almost every other known machine. The framing for supporting the trunnions, which one without experience would suppose should be very rigid and solid, is found to answer best when composed of timber, and still better when this timber is laid up in a manner that allows the structure to spring and [107] yield. Starting at the dies, and following back through the details of a trip-hammer to the driving power, the apprentice may note how many parts contribute to this principle of elasticity: First��the wooden helve, both in front of and behind the trunnion; next��the trunnion bar, which is usually a flat section mounted on pivot points; third��the elasticity of the framing called the 'husk,' and finally the frictional belt. This will convey an idea of the elasticity required in connecting the hammer-head with the driving power, a matter to be borne in mind, as it will be again referred to.1.

THREE:"What, a Netherlander!��a Netherlander! All traitors! You are helping the Germans, but we are not afraid of either German or Netherlander."The religious tendency of Seneca��s philosophy appears rather in his psychology than in his metaphysics, in the stress which he lays on human immortality rather than in his discussions on creation and divine providence. His statements on this subject are not, indeed, very consistent, death being sometimes spoken of as the end of consciousness, and at other times, as the beginning of a new life, the ��birthday of eternity,�� to quote a phrase afterwards adopted by Christian preachers. Nor can we be absolutely certain that the promised eternity is not merely another way of expressing the soul��s absorption into and identification with the fiery element whence it was originally derived. This, however, is an ambiguity to be met with in other doctrines of a spiritual existence after death, nor is it entirely absent from the language even of Christian theologians. What deserves attention is that, whether the future life spoken of by Seneca be taken in a literal or in a figurative sense, it is equally intended to lead our thoughts away from the world of sensible experience to a more ideal order of things; and, to that extent, it falls in with the more general religious movement of the age. Whether Zeller is, for that reason, justified in speaking of him as a Platonising Stoic seems more questionable; for the Stoics always agreed with Plato in holding that the soul is distinct from and superior to the body, and that it is consubstantial with the animating principle of Nature. The same circumstances which were elsewhere leading to a revival of Platonism, equally tended to develope this side of Stoicism, but it seems needless to seek for a closer connexion between the two phenomena.376

THREE:It is, after all, very questionable whether human happiness would be increased by suppressing the thought of death as something to be feared. George Eliot, in her Legend of Jubal, certainly expresses the contrary opinion.180 The finest edge of enjoyment would be taken off if we forgot its essentially transitory character. The free man may, in Spinoza��s words, think of nothing less than of death; but he cannot prevent the sunken shadow from throwing all his thoughts of life into higher and more luminous relief. The ideal enjoyment afforded by literature would lose much of its zest were we to discard all sympathy with the fears and sorrows on which our mortal condition has enabled it so largely to draw��the lacrimae rerum, which Lucretius himself has turned to such admirable account. And the whole treasure of happiness due to mutual affection must gain by our remembrance that the time granted for its exercise is always limited, and may at any moment be brought to an end��or rather, such an94 effect might be looked for were this remembrance more constantly present to our minds.��He said, this morning, we had helped him a lot and he didn��t have money to pay us,�� Larry answered. ��He offered us a joy-ride.��

THREE:The author of the Leviathan has sometimes been represented as one who carried the Baconian method into politics, and prepared the way for its more thorough application to psychology by Locke. But this view, which regards the three great leaders of English philosophy in the seventeenth century as successive links in a connected series, is a misapprehension of history, which could only have arisen through leaving out of account the contemporary development of Continental speculation, and through the inveterate habit of looking on the modern distinction between empiricism and transcendentalism as a fundamental antithesis dividing the philosophers of every epoch into two opposing schools. The truth is that, if the three writers just mentioned agree in deriving knowledge solely from experience, they agree in nothing else; and that their unanimity on this one point does not amount to much, will be evident if we consider what each understood by the notion in question.
