ANALYTIC OF PRINCIPLES. 361 all experience, the possibility is given of synthetic judg- ments a priori concerning objects of possible experience. Such judgments, in so far as they are not based on higher and more general cognitions, are termed "principles," and the system of them — to be given, with the table of the categories as a guide, in the Analytic of Principles or the Doctrine of the Faculty of Juclg.ment^furnishes the out- lines of "pure natural science." When thus the rules of tTie subsumption to be effected have been found in the pure concepts, and the conditions and criteria of the subsump- tion in the schemata, it remains to indicate the principles which the understanding, through the aid of the schemata, actually produces a priori from its concepts. The principle of quantity is the Axiom of Intuition, . the principle of quality the Anticipation of Perception; tlTe principles of relation are termed Analogies of Experi- ence, those of modality Postulates of Empirical Thought in General. The first runs, " All intuitions are extensive quantities " ; the second, " In all phenomena sensation, and the real which corresponds to it in the object, has an inten- sive quantity, i. e., a degree." The principle of the "Anal- ogies" is, " All phenomena, as far as their existence is con- cerned, are subject a priori to rules, determining their mutual relation In time" (in the second edition this is stated as follows ; " Experience is possible only througJi the representation of a necessary connection of percep, tions"). As there are three modes of time, there result V three "Analogies," the principles of permanence,^ of suc- cession (production), and of coexistence. These are: (i)
- ' In all changes of phenomena the substance is permanent,
and its quantum is neither increased nor diminished in nature." (2) " All changes take place according to the law of connection between cause and effect"; or, " Everything that happens (begins to be) presupposes something on which it follows according to a rule." (3) " All substances, in so far as they are coexistent, stand in complete community, that is, reciprocity, one to another." And, finally, the three " Postulates ": "That which agrees with the formal' conditions of experience (in intuition and in concepts) is 1 possible." "That which is connected with the material/ I
