For it consists of a series of discourses in praise of love, so arranged as to typify the manner in which Greek speculation, after beginning with mythology, subsequently advanced to physical theories of phenomena, then passed from the historical to the contemporary method, asking, not whence did things come, but what are they in themselves; and finally arrived at the logical standpoint of analysis, classification, and induction.
"We beseech all residents in the municipality to guard the highest interests of all the inhabitants and of those who are hostages of the German Army, and not to commit any assault on the soldiers of this army.
"Keep the doctor to yourself," Maitrank snapped. "I'm all right. See, there is nothing in any of my pockets. My overcoat could not----"This analogy with subsequent developments is aided, so far as it goes, by the admixture of a certain Platonic element with Virgils Stoicism, shown chiefly by the references to an antenatal existence of the soul, introduced for the purpose of bringing Romes future heroes on the scene. This, however, is the last example of an attempt on the part of a Roman writer to combine Platos teaching with Stoicism.286 At a time when the Romans were more conscious of their literary dependence on Greece than was the case after the Augustan age had reached its zenith, they were probably drawn by the beauty of its literary form to study a system which could otherwise interest them but little. Thus, not only is Cicero full of admiration for Platoas, indeed, might be expected with so highly cultivated a disciple of the Academybut Cato, according to the well-known story, spent his last hours reading and re-reading the Phaedo; and his nephew Brutus also occupied an intermediate position between the Old Academy and the Porch. The Roman love of simplification and archaism induced subsequent thinkers either to let Platonism drop altogether, or to study those elements in which it differed from the pure naturalistic doctrine under their Pythagorean form. It may even be doubted whether Virgils psychology is not derived from Pythagoras rather than from Plato; Ovid, so far as he philosophises at all, is unquestionably a follower of the former;287 and in the moral teaching of the Sextii, who flourished under Augustus, Pythagorean principles are blended with Stoicism.288 It is another manifestation of the same effort to grasp every Greek doctrine by its roots, that Horace should proclaim himself the disciple of Aristippus rather than of Epicurus.289 Even he, however, feels183 himself drawn with advancing years towards the nobler faith which was now carrying all before it.290
It was Hetty who came back with the second message that the Countess would see her visitor presently in her dressing-room. The girl started as she recognized the features of the detective.
In practice this difference of effect on the top and bottom, or between the anvil and hammer sides of a piece, is much greater than would be supposed. The yielding of the soft metal on the top cushions the blow and protects the under side from the force. The effect produced by a blow struck upon hot iron cannot be estimated by the force of the blow; it requires, to use a technical term, a certain amount of force to "start" the iron, and anything less than this force has but little effect in moving the particles and changing the form of a piece.
