ONE:CHAPTER X. MACHINERY FOR TRANSMITTING AND DISTRIBUTING POWER."I have been in every room," she said. "There is positively nobody there. I shall have to send you away for a change of air. If you have no further dreams to tell me we had better go to bed."

ONE:In no other branch of machinery has so much research and experiment been made during eighty years past as in steam machinery, and, strange to say, the greater part of this research has been directed to the details of engines; yet there has been no improvement made during the time which has effected any considerable saving of heat or expense. The steam-engines of fifty years ago, considered as steam-using machines, utilised nearly the same proportion of the energy or power developed by the boiler as the most improved engines of modern constructiona fact that in itself indicates that an engine is not the vital part of steam machinery. There is not the least doubt that if the efforts to improve steam-engines had been mainly directed to economising heat and increasing the evaporative power of boilers, much more would have been accomplished with the same amount of research. This remark, however, does not apply to the present day, when the principles of steam-power are so well understood, and when heat is recognised as the proper element to deal with in attempts to diminish the expense of power. There is, of course, various degrees of economy in steam-using as well as in steam-generating machinery; but so long as the best steam machinery does not utilise but one-tenth or one-fifteenth part of the heat represented in the fuel burned, there need be no question as to the point where improvements in such machinery should be mainly directed.The style of polemics adopted on this occasion, whatever else may be its value, will serve excellently to illustrate the general dialectic method of attack. When Plato particularly disliked a class of persons, or an institution, or an art, or a theory, or a state of consciousness, he tried to prove that it was confused, unstable, and self-contradictory; besides taking full advantage of any discredit popularly attached to it. All these objections are brought to bear with full force against pleasure. Some pleasures are delusive, since the reality of them falls far short of the anticipation; all pleasure is essentially transitory, a perpetual becoming, never a fixed state, and therefore not an end of action; pleasures which ensue on the satisfaction of desires are necessarily accompanied by pains and disappear simultaneously with them; the most intense, and for that reason the most typical, pleasures, are associated with feelings of shame, and their enjoyment is carefully hidden out of sight.
