Categories are the forms according to which the combining unity of self-consciousness (synthetic unity of apperception) pluralizes itself through the various functions involved in the constitution of objectivity in different types of the one act of thought, viz.
The clue to the discovery of transcendental conditions Kant finds in the existence of judgments, most manifest in mathematics and in the pure science of nature, which are certain, yet not trifling, necessary and yet not reducible to identities, synthetic therefore and a priori, and so accounted for neither by Locke nor by Leibnitz.
These ancient Exopterygota were synthetic in type, and included insects that may, with probability, be regarded as ancestral to most of the existing orders.
It may therefore be said that caoutchouc has been already artificially or synthetically prepared, and the possibility of producing synthetic rubber cheaply on a commercial scale remains the only problem.
Many synthetic processes are known for the production of acridine and its derivatives.
This knowledge, however, is by no means positivistic or empirical, but on the contrary it is dialectical and a priori synthetic, brought about by the spiritual categories; and from it there constantly arise new problems, an ever new position of the fundamental categories.
An important nucleus-synthetic reaction is the saponification of nitriles, which may be obtained by the interaction of potassium cyanide with a halogen substitution derivative or a sulphonic acid.
Chief among these encumbering presuppositions was that of a fundamental distinction between perception and conception and consequent upon it between the synthetic and the analytic use of thought.
It was, as we have seen, this conception of thought as essentially synthetic for which Kant paved the way in his polemic against the formalism of his continental predecessors.
3, p. 319.) Ammonia finds a wide application in organic chemistry as a synthetic reagent; it reacts with alkyl iodides to form amines, with esters to form acid amides, with halogen fatty acids to form amino-acids; while it also combines with isocyanic esters to form alkyl ureas and with the mustard oils to form alkyl thioureas.
On account of the readiness with which it condenses with various compounds, benzaldehyde is an important synthetic reagent.
The compounds formed by the action of magnesium on alkyl iodides in the cold have been largely used in synthetic organic Gri chemistry since V.
It may be urged in reply that the synthetic philosophy could be made consistent by transferring the knowable resistance and persistence of the unknowable noumenon to knowable phenomena on the one hand, and on the other hand by maintaining that all phenomena from the original nebula to the rise of consciousness are only ` 0 impressions produced on consciousness through any of the senses," after all.
The truth is that his theory of evolution can be carried through the whole process without a break, only by giving the synthetic philosophy a materialistic interpretation, and by adhering consistently to [[[Metaphysical Idealism]] Spencer's own materialistic definition of evolution; otherwise there will be a break at least between life and mind.
As to the origin of knowledge, Kant's position is that sense, outer and inner, affected by things in themselves, receives mere sensations or sensible ideas (Vorstellungen) as the matter which sense itself places in the a priori forms of space and time; that thereupon understanding, by means of the synthetic unity of apperception, " I think " - an act of spontaneity beyond sense, in all consciousness one and the same, and combining all my ideas as mine in one universal consciousness - and under a priori categories, or fundamental notions, such as substance and attribute, cause and effect, &c., unites groups of sensations or sensible ideas into objects and events, e.g.
A house, one ball moving another; and that, accordingly, perception and experience, requiring both sense and understanding, are partly a posteriori and partly a priori, and constitute a knowledge of objects which, being sensations combined by synthetic unity under a priori forms, are more than mere sensations, but less than things in themselves.
Kant had said that the synthetic unity " I think " is in all consciousness one and the same, meaning that I am always present to all my ideas.
Kant further insisted that this apperception, " I think," is an act of spontaneity, distinct from sense, necessary to regarding all my ideas as mine, and to combining them in a synthetic unity of apperception; which act Fichte afterwards developed into an active construction of all knowledge, requiring will directed to the end of duty.
He accepts on the whole the system of synthetic understanding which Kant superimposed on mere association.
After this letter it cannot be doubted that Kant not only differed wholly from Fichte, both about the synthetic unity of apperception and about the thing in itself, but also is to be construed literally throughout.
In working out this process he supposes that reason throws into consciousness a priori categories, synthetic predicates a priori, or, as he also calls them, " dialectic percepts."
The most important data bearing upon the first great period are given elsewhere in this work, and it is proposed to offer here a more general survey.5 To the prehistoric ages belong the palaeolithic and neolithic flints, from the distribution of which an attempt might be made to give a synthetic sketch of early Palestinian man.6 A burial cave at Gezer has revealed the existence of a race of slight build and stature, muscular, with elongated crania, and thick and heavy skull-bones.
Owing to the manufacture of synthetic indigo by German chemists the export trade in indigo, which was formerly the most important business carried on by European capital in India, has been almost entirely ruined.
The manufacture of synthetic indigo by German chemists has greatly affected the growth and manufacture of indigo, the indigo factories decreasing in1904-1905from 402 to 252.
Analytic and Synthetic Deduction.
This done, as the major is convertible, the analytic order - P-M, S-P, S-M - was easily inverted into the synthetic order - M-P, S-M, S-P; and in this progressive order the deduction as now taught begins with the centripetal force of the sun as real ground, and deduces the facts of planetary motion as consequences.
Really, we first experience that particular causes have particular effects; then induce that causes similar to those have effects similar to these; finally, deduce that when a particular cause of the kind occurs it has a particular effect of the kind by synthetic deduction, and that when a particular effect of the kind occurs it has a particular cause of the kind by analytic deduction with a convertible premise, as when Newton from planetary motions, like terrestrial motions, analytically deduced a centripetal force to the sun like centripetal forces to the earth.
Moreover, causal induction is itself both synthetic and analytic: according as experiment combines elements into a compound, or resolves a compound into elements, it is the origin of a synthetic or an analytic generalization.
So long as the relation of the nominal to the real essence has no other background than Locke's doctrine of perception, the conclusion that what Kant afterwards calls analytical judgments a priori and synthetic judgments a posteriori exhaust the field follows inevitably, with its corollary, which Locke himself has the courage to draw, that the natural sciences are in strictness impossible.
Lotze's logic then, is formal in a sense in which a logic which does not find the conception of synthetic truth embarrassing is not so.
It is a most important synthetic reagent; with sodium or sodium ethylate it forms sodio-malonic ester, which reacts readily with alkyl halides, forming alkyl malonic esters, which are again capable of forming sodium derivatives, that by further treatment with alkyl halides yield the di-alkyl malonic esters.
