The invariability of the properties of the phases is in close connexion with the invariability of the pressure (called maximum tension).
In Hume's theory, which Mill formally adopted with a modification,[3] there is nothing observable but the constancy or invariability of the connexion.
The Experimental Methods proceed on the assumption that there is other outward and visible evidence of causal connexion than invariability of sequence.
After all, the only point recognised in the theory as observable is the invariability of the sequence.
If this conception were exact, the principle of the invariability of mass would naturally be destroyed.
Moreover, the marks are traced on the plane of the neutral fibres[2] exposed, and the invariability of their distance apart is thus assured, even when a change is made in the way the rule is supported.
And the growth of new out of old forms is of necessity a sequence, and falls under the law of invariability of sequences, and becomes the subject-matter of Science.
We discover invariability much faster than we can discover causation; and having discovered invariability in any given case, we presume causation even when we cannot yet show it, and use language in accordance with that presumption.
His steady watch over them showed the invariabilityof their position with regard to the terminator; and this is as much as to say that the regions of day and night do not shift on the surface of the planet.
One fact well ascertained as regards both species is the invariability of the type.
The other school, reposing on the great principle of the invariability of the laws of Nature, insisted that affairs had always gone on at the same rate and in the same way as they do now.
The invariability of that law is indicated by the numberless ages through which it has been maintained, its universality by its holding good in the life of the meanest individual.
But out of this invariability of natural causes variations in their condition of action arise, and it is these that affect organic forms.
Can he not see that the degradation and wickedness of humanity are in striking contrast to the "glorious perfection and invariability of the order of nature"?
The opinion so implicitly entertained regarding the invariability of the force of gravity at any given point of the earth's surface, has in some degree been controverted by the gradual rise of large portions of the earth's surface.
This invariability of form presupposes also a great invariability in the distribution of relations of density in the interior of the globe.
The usage of money has taken from the unity of value that character of invariability which it ought necessarily to possess.
But how can its invariability be assured if a material support is given to it open to incessant fluctuations of value resulting from all the speculations to which what ever can be bought and sold is submitted?
The memoir in which Laplace communicated his results on the invariability of the mean motions or mean distances, is dated 1773.
We pause here to remark that, throughout the whole inquiry into the question of miracles, we meet with nothing from theologians but mere assumptions, against which the invariability of the known order of nature steadily opposes itself.
Life favours no presumption for the suspension of law, but, on the contrary, whilst acting in nature, universally exhibits the prevalence and invariability of law.
The whole theory of this abortive design of creation, with such impotent efforts to amend it, is emphatically contradicted by the glorious perfection and invariability of the order of nature.
And science does not rest for us on sure foundations unless the invariability of the laws of nature is admitted.
Cartesianism affirmed the two positive axioms of the supremacy of reason, and the invariability of the laws of nature; and its instrument was a new rigorous analytical method, which was applicable to history as well as to physical knowledge.
The two axioms which he launched upon the world--the supremacy of reason, and the invariability of natural laws--struck directly at the foundations of orthodoxy.
The invariability of nature, as he conceived it, was true of the emotions and the will, as well as of the intellect.
There is in the content of tradition an invariability which could not exist if it were a dual composite, as is the constitution of the germ-plasm.
Euclid preferred to assert as a postulate, directly, the fact that all right angles are equal; and hence his postulate must be taken as equivalent to the principle of invariability of figures, or its equivalent, the homogeneity of space.
But this method would not be valid unless on the assumption of the invariability of figures, which would have to be asserted as an antecedent postulate.
Such a mechanism is in keeping with the manner in which the course of nature is fulfilled, and bears in its very style the impress of invariability of action.
The permanence of organic forms is altogether dependent on the invariability of the material conditions under which they live.
Invariability can only be observed, in any of the methods of induction, by collecting more and more instances, or repeating experiments.
So that invariability will not really be inferred from a single experiment; besides that every prudent inquirer repeats his experiments, if only to guard against his own liability to error.
He then speaks of the chief characteristic of nature being invariability of law.
It is this invariability of sequence which can alone give value to experience, and render education, in the true sense, possible.
The invariabilityof the belief is with him the real guarantee.
The invariability of belief, tested by the inconceivableness of its negation, "is our sole warrant for every demonstration.
Passing from inorganic to organic forms, our author remarks that their permanence is altogether dependent 'on the invariability of the material conditions under which they live.
The question is about an invariable measure of value, and your proof of invariability is that it will measure profits as well as labour, which every variable measure will also do.
I still think that the invariability of your measure is the definition with which you set out, and not the conclusion to which you arrive by any legitimate argument.
