TWO:The Alexandrian Sceptics general arguments against the possibility of knowledge resolve themselves into a criticism of what Sir W. Hamilton called Natural Realism, somewhat complicated and confused by a simultaneous attack on the theory of natural morality conceived as something eternal and immutable. They are summed up in the famous ten Tropes. Of these the first three are founded on the conflicting sensations produced by the same object when acting on different animalsas is inferred from the marked contrast presented by their several varieties of origin and structure,on different men, and on the different senses of the same individual. The fourth, which has evidently an ethical bearing, enlarges on the changes in mens views caused by mental and bodily changes, according to their health, age, disposition, and so forth. The next five Tropes relate to circumstances connected with the objects themselves: their distance and position as regards the spectator, the disturbance produced in their proper action by external influences such as air and light, together with the various membranes and humours composing the organs of sense through which they are apprehended; their quantitative variation, involving as it does opposite effects on the senses, or as with medicines, on the health; the law of relativity, according to which many things are only known when taken in company with others, such as double and half, right and left, whole and part; comparative frequency or rarity of occurrence, as with comets, which, while really of much less importance than the sun, excite much more interest from their being so seldom seen. Finally, the tenth Trope is purely ethical, and infers the non-existence of a fixed moral standard from the divergent and even opposite customs prevailing among different nations.297
THREE:She waited just for a moment in eager expectation. There was the form again, and then the spurt and flare of gas. What would anybody want gas for at this time of the day? The question was answered immediately, for a hand went over the gas flame holding something that looked like a kettle to the flame. Then the hand disappeared and nothing more was to be seen, despite Hetty's patience.
