Such an optimistic postulate, however, as the reader must have repeatedly observed, is made not only despite all experience but in ignorance of the conditions under which alone ideals are framed and retain their significance.

To postulate something that is not phenomena as the cause of phenomena, is like discussing the possibility of a bird's flight and dismissing the possibility of an atmosphere. Secondly, causation can give no clue to a God because the search for causes is a search for the conditions under which phenomena occur.

We have succeeded in defining this entropy by demonstrating, as has been said, a certain number of propositions which spring from the postulate of Clausius; it is, therefore, natural to suppose that this postulate itself contains in potentia the very idea of a necessary evolution of physical systems. But as it was first enunciated, it contains it in a deeply hidden way.

But I also agree with him that the difference which exists in our premises is one ofprofound importance, philosophically considered;” and not to be dismissed while any part of the case of either of us has not been fully examined and discussed. In his present statement of the Universal Postulate, Mr.

The postulate once formulated, we seek in the flux for confirmations of it, and thus construct a system of 'facts' which are relative to it; that is how the postulate reacts upon experience. If, on the other hand, this process of selection is unfruitful, and the confirmations of our rule turn out infinitesimal, we alter the rule; and thus the 'facts' in the case reject the postulate.

She looked hurt, as if she had been unfairly forced to the logic of her postulate, and Hewson was not altogether pleased with himself; but at least he had had his revenge in making her realize the man's vacuity. He tried to get her back to talk about "Ghosts," again, but she answered with indifference, and just then he was arrested by something a man was saying near the head of the table.

Just as mathematicians and physicists, in their systems, are wont to postulate the fundamental and undeniable truths they are concerned with, or what they take for such and require to be taken for granted, so Mr. Darwin postulates, upon the first page of his notable work, and in the words of Whewell and Bishop Butler: 1.

If, therefore, it should turn out, which seems absurd, that college-educated girls are not as attractive as other women with less advantages, it will have to be admitted that something is the matter with the young ladies, which is preposterous, or that the system is still defective. For the postulate that everybody ought to be attractive cannot be abandoned for the sake of any system.

It might be safe and legitimate enough, when we find a fossil organism imbedded in the earth, to ascribe its production to the ordinary law of generation, even although we had not witnessed the fact of its birth, provided the same species is known to have existed previously; but when we find new races coming into being, for which the ordinary law of derivation cannot account, we are not at liberty to apply the same rule to a case so essentially different, and still less to postulate a spontaneous generation, or a transmutation of species, for which we have no experience at all.

But so long as the cardinal number is inferred from the collections, not constructed in terms of them, its existence must remain in doubt, unless in virtue of a metaphysical postulate ad hoc.
