To the reduction of the concept of law to an economic factor, which depends upon the priority and autonomy of Economic in relation to Ethic, is devoted a considerable portion of the latter part of the _Philosophy of the Practical,_ and it is easy to see that an elaborate treatment of this problem was necessary, owing to the confusion as to its true nature that has for so long existed in the minds of thinkers, owing to their failure to grasp the above distinction. In Great Britain indeed, where precedent counts for so much in law, the ethical element is very often so closely attached as to be practically indistinguishable from it, save by the light of the Crocean analysis. In the _Logic as Science of the Pure Concept_ will be found much to throw light upon the _Philosophy of the Practical,_ where the foreshortening of certain proofs (due to concentration upon other problems) may appear to leave loopholes to objection. Thought will there be found to make use of language for expression, though not itself language; and it will be found useless to seek logic in words, which in themselves are always æsthetic. For there is a duality between intuition and concept, which form the two grades or degrees of theoretic knowledge, as described also in the _Æsthetic._ There are two types of concept, the _pure_ and the _false_ or _pseudo-concept,_ as Croce calls it. This latter is also divided into two types of representation--those that are concrete without being universal (such as the cat, the rose), and those that are without a content that can be represented, or universal without being concrete, since they never exist in reality (such are the triangle, free motion). The first of these are called empirical pseudo-concepts, the second abstract pseudo-concepts: the first are represented by the natural, the second by the mathematical sciences. Of the _pure concept_ it is predicated that it is ineliminable, for while the pseudo-concepts in their multiplicity are abolished by thought as it proceeds, there will always remain one thought namely, that which thinks their abolition. This concept is opposed to the pseudo-concepts: it is ultra or omni-representative. I shall content myself with this brief mention of the contents of the _Philosophy of the Practical_ and of the _Logic_ upon which I am now working.
