ONE:The history of Greek philosophy, whether conceived in this comprehensive sense or as an erudite investigation into matters of detail, is a province which the Germans have made peculiarly their own; and, among German scholars, Dr. Zeller is the one who has treated it with most success. My obligations to his great work are sufficiently shown by the copious references to it which occur throughout the following pages. It is in those instancesand they are, unfortunately, very numerouswhere our knowledge of particular philosophers and of their opinions rests on fragmentary or second-hand information, that I have found his assistance most valuable. This has especially been the case with reference to the pre-Socratic schools, the minor successors of Socrates, the earlier Stoics, the Sceptics, and the later Pythagoreans. I must, however, guard against the supposition that my work is, in any respect, a popularisation or abridgment of Zellers. To popularise Zeller would, indeed, be an impertinence, for nothing can be more luminous and interesting than his style and general mode of exposition. Nor am I playing the part of a finder to a large telescope; for my point of view by no means coincides with that of the learned German historian. Thus, while my limits have obliged me to be content with a very summary treatment of many topics which he has discussed at length, there are others, and those, in my opinion, not the least important, to which he has given less space than will be found allotted to them here. On several questions, also, I have ventured to controvert his opinions, notably with reference to the Sophists, Socrates, Aristotle, and Plotinus. My general way of looking at the Greeks and their philosophy also differs from his. And the reasons which have led me to follow an independent course in this respect involve considerixations of such interest and importance, that I shall take the liberty of specifying them in some detail.Herr Max Kronin nodded approvingly.

ONE:This, again, reaches the proposition that power is heat, and heat is power, the two being convertible, and, according to modern science, indestructible; so that power, when used, must give off its mechanical equivalent of heat, or heat, when utilised, develop its equivalent in power. If the whole amount of heat represented in the fuel used by a steam-engine could be applied, the effect would be, as before stated, from ten to fifteen times as great as it is in actual practice, from which it must be inferred that a steam-engine is a very imperfect machine for utilising heat. This great loss arises from various causes, among which is that the heat cannot be directly nor fully communicated to the water. To store up and retain the water after it is expanded into steam, a strong vessel, called a boiler, is required, and all the heat that is imparted to the water has to pass through the plates of this boiler, which stand as a wall between the heat and its work.VIII.
