In the judgment of D'Alembert the Cartesan theory was the best that the observations of the age admitted; and " its explanation of gravity was one of the most ingenious hypotheses which philosophy ever imagined."
The danger lies not in forming such hypotheses, but in regarding them as final, or as more than an attempt to throw light upon our observation of the phenomena.
All his knowledge of Semitic languages he used in a "conservative Higher Criticism," which is maintained in the following works: The Pentateuch Vindicated from the Aspersions of Bishop Colenso (1863), Moses and the Prophets (1883), The Hebrew Feasts in their Relation to Recent Critical Hypotheses Concerning the Pentateuch (1885), The Unity of the Book of Genesis (1895), The Higher Criticism of the Pentateuch (1895), and A General Introduction to the Old Testament, vol.
In conclusion, it is noteworthy that though resorting to utterly fanciful hypotheses respecting the order of the development of the world, Anaximander agrees with modern evolutionists in conceiving the heavenly bodies as arising out of an aggregation of diffused matter, and in assigning to organic life an origin in the inorganic materials of the primitive earth (pristine mud).
Thus in the end of the 17th century the seed was sown which has at intervals brought forth recurrent crops of evolutional hypotheses, based, more or less completely, on general reasonings.

As a matter of fact, discussions of method and the criticism of hypotheses and assumptions are very rarely found in early economic works.

Only three hypotheses as to the origin of Endopterygota can be suggested as possible, viz.: - (i) That some of the Palaeozoic insects, though we infer them to have been exopterygotous, were really endopterygotous, and were the actual ancestors of the existing Endopterygota; (2) that Endopterygota are not descended from Exopterygota, but were derived directly from ancestors that were never winged; (3) that the predominant division - i.e.

Although such hypotheses could contribute nothing directly to the development of a science which laid especial claim to experimental investigations, yet indirectly they stimulated inquiry into the nature of the " essence " with which the four " elements " were associated.
In 1860 there prevailed such a confusion of hypotheses as to the atom and molecule that a conference was held at Karlsruhe to discuss the situation.
The theory of valency as a means of showing similarity of properties and relative composition became a dominant feature of chemical theory, the older hypotheses of types, radicals, &c.
But he fought in a futile cause; to explain the facts put forward by Dumas he had to invent intricate and involved hypotheses, which, it must be said, did not meet with general acceptance; Liebig seceded from him, and invited Wohler to endeavour to correct him.

The "axioms" of geometry are the fixed conditions which occur in the hypotheses of the geometrical propositions.
In "applied mathematics" the "deductions" are given in the shape of the experimental evidence of natural science, and the hypotheses from which the "deductions" can be deduced are sought.
Newton's Hypotheses non fingo was a proud boast, but it rests upon an entire misconception of the capacities of the mind of man in dealing with external nature.
None of the detailed hypotheses which were based on this idea stood the test of criticism, but towards the end of the 19th century the researches of J.
The mathematical theory which was constructed by Poisson, and extended and freed from doubtful hypotheses by Kelvin, has been elaborated by other investigators, notably F.
Of the customary three themes which he suggested for his trial lecture, that "On the Hypotheses which form the Foundation of Geometry" was chosen at the instance of Gauss, who was curious to hear what so young a man had to say on this difficult subject, on which he himself had in private speculated so pro foundly (see Geometry, Non-Euclidian).
All the hypotheses about the causation of new growths seek to explain the secret of this individuality or " autonomy," as they recognize that the mystery of the origin of the great majority of tumours would be solved if we could trace how or why the tissue elements in which they develop first took on this abnormal growth.
Many of the hypotheses of the past put forward - to explain cancer must be discarded, in view of the facts brought to light by the comparative and experimental research of recent times.
Henser, Bencke, Adami, Marchand and others have also put forward hypotheses to account for the origin of new growths.
The foregoing hypotheses have all sought the origin of new growths in some intrinsic cause which has altered the characters of the cell or cells which gave rise to them, but none of them explain the direct exciting cause.
Cole (1635-1716) (see above) published mechanical hypotheses concerning the causation of fevers which closely agree with those of the Italian iatro-mechanical school.
The first two books enable us better than anything else in ancient literature to appreciate the boldness and, on the whole, the reasonableness of the ancient mind in forming hypotheses on great matters that still occupy the investigations of physical science.
His system, however, like all others, is built in the main upon hypotheses incapable at present of quite satisfactory verification, such, for example, as the conjectural reading " Gargamish " for a group of symbols which recurs in inscriptions from Jerablus and elsewhere.
The various hypotheses, dogmas, proposals, as to the family, to capital, &c., are merely propositions measurable by considerations of utility and a balance of expediencies.

For a true appreciation of the chaotic polytheism that reveals itself even in the earliesttexts it would be necessary to be able to trace its development, stage by stage, out of a number of naive primitive cults; but the period of growth lies behind recorded history, and we are here reduced to hypotheses and a posleriori reconstructions.
