most philosophical of those various writers. Bierling first of all excludes from the concept of law the modes of man's conduct toward God, toward himself, and toward animals; but he gives no serious reason for this. He then arrives, by a mere arbitrary act, at the limiting of the concept of law to the manner of men's conduct among themselves, and defines rights in the juridical sense (as he calls it: "in general, all that men living together in any sort of community reciprocally recognize as a norm and rule of this living together"). He then introduces into the concept thus defined, not by deduction, but as the result of a second arbitrary act, the concept of exteriority, adding that, "the object of law is a definite _external_ procedure of man toward man."[40] In all this is evident the bad influence of jurisprudence and of its empirical preoccupations. [Sidenote: _legalism and moral casuistic._] VIII. Ethical legalism became a bitter question for Christianity, precisely because of the contest between lofty Christian morality and its legalitarian form, chiefly inherited from Judaism. In the ancient world there is almost no trace of the question, just because the struggle was never acute.[41] Hence the difficulties debated among the patristics and the scholastics as to derogability from divine laws and the consequent distinctions between a perfect and an imperfect moral life, between precepts and counsels; and as recourse is had to precedents in judicial questions, so here with these ethical problems concerning exceptions made by God to the moral law, to the precepts of the Bible (where some were not beautiful).[42] The practical needs of confession give origin to books on casuistic, of which collections exist dating from the fourteenth and fifteenth centuries. The Reformation manifested aversion to these treatises: Luther said that moral theologians had first extinguished in men the fear of God and had then placed soft cushions beneath their hands and feet; and Melanchthon lamented that the Christian Republic was honoured _theologastrorum sententiis de conscientiae casiobus, inestricabilibus, ubi nunquam non ex quaestione quaestio nascitur,_ and called them _conscientiarum cauteria._[43] [Sidenote: _Probabilitism and Jesuitic morality._]
