For if the objects to which those principles must be applied were things in themselves, it would be quite impossible to cognize aught concerning them synthetically a priorI. But they are nothing but phenomena; a complete knowledge of which--a knowledge to which all principles a priori must at last relate--is the only possible experience. When we have contracted a habitude and intimacy with any person; though in frequenting his company we have not been able to discover any very valuable quality, of which he is possessed; yet we cannot forebear preferring him to strangers, of whose superior merit we are fully convinced. It is as little contrary to reason to prefer even my own acknowledgeed lesser good to my greater, and have a more ardent affection for the former than the latter. We have command over our mind to a certain degree, but beyond that, lose all empire over it: And it is evidently impossible to fix any precise bounds to our authority, where we consult not experience. Now, in the first place, if we have a proposition which contains the idea of necessity in its very conception, it is a if, moreover, it is not derived from any other proposition, unless from one equally involving the idea of necessity, it is absolutely priorI. Secondly, an empirical judgement never exhibits strict and absolute, but only assumed and comparative universality (by induction); therefore, the most we can say is--so far as we have hitherto observed, there is no exception to this or that rule. From this principle I have accounted for that species of probability, derived from analogy, where we transfer our experience in past instances to objects which are resembling, but are not exactly the same with those concerning which we have had experience. 3. In regard to the third motive for the preliminary choice of a party in this war of assertions, it seems very extraordinary that empiricism should be utterly unpopular. It is easy to multiply algebraical problems to infinity, nor is there any end in the discovery of the proportions of conic sections; though few mathematicians take any pleasure in these researches, but turn their thoughts to what is more useful and important.
