ONE:Yet, if the conception of unity was gaining ground, the conceptions of purpose and vitality must have been growing weaker as the triumph of brute force prolonged itself without limit or hope of redress. Hence Stoicism in its later form shows a tendency to dissociate the dynamism of Heracleitus from the teleology of Socrates, and to lean on the former rather than on the latter for support. One symptom of this changed attitude is a blind worship of power for its own sake. We find the renunciation of pleasure and the defiance of pain appreciated more from an aesthetic than from an ethical point of view; they are exalted almost in the spirit of a Red Indian, not as means to higher ends, but as manifestations of unconquerable strength; and sometimes the highest sanction of duty takes the form of a morbid craving for applause, as if the universe were an amphitheatre and life a gladiatorial game.102With a white oblong sheet of paper in his pocket with the signature of the chief magistrate at Bow Street, Prout went down jauntily to call upon Lawrence. The latter looked at him smilingly.

THREE:For disadvantages there is, on the other hand, a want of uniformity in fittings that prevents their interchange from one part of a line shaft to the othera matter of great importance, as such exchanges are frequently required. A line shaft, when constructed with pieces of varying diameter, is special machinery, adapted to some particular place or duty, and not a standard product that can be regularly manufactured as a staple article by machinists, and thus afforded at a low price. Pulleys, wheels, bearings, and couplings have all to be specially prepared; and in case of a change, or the extension of lines of shafting, cause annoyance, and frequently no little expense, which may all be avoided by having shafts of uniform diameter. The bearings, besides being of varied strength and proportions, are generally in such cases placed at irregular intervals, and the lengths of the different sections of the shaft are sometimes varied to suit their diameter. With line shafts of uniform diameter, everything pertaining to the shaftsuch as hangers, couplings, pulleys, and bearingsis interchangeable; the pulleys, wheels, bearings, or hangers can be placed at pleasure, or changed from one part of the shaft to another, or from [47] one part of the works to another, as occasion may require. The first cost of a line of shafting of uniform diameter, strong enough for a particular duty, is generally less than that of a shaft consisting of sections varying in size. This may at first seem strange, but a computation of the number of supports required, with the expense of special fitting, will in nearly all cases show a saving.
