The intelligent alternative is to revise, adapt, expand and alter them. The problem is one of continuous, vital readaptation. The popular objection to casuistry is similar to the popular objection to the maxim that the end justifies the means. It is creditable to practical moral sense, but not to popular logical consistency. For recourse to casuistry is the only conclusion which can be drawn from belief in fixed universal principles, just as the Jesuit maxim is the only conclusion proper to be drawn from belief in fixed ends. Every act, every deed is individual. What is the sense in having fixed general rules, commandments, laws, unless they are such as to confer upon individual cases of action (where alone instruction is finally needed) something of their own infallible certainty? Casuistry, so-called, is simply the systematic effort to secure for particular instances of conduct the advantage of general rules which are asserted and believed in. By those who accept the notion of immutable regulating principles, casuistry ought to be lauded for sincerity and helpfulness, not dispraised as it usually is. Or else men ought to carry back their aversion to manipulation of particular cases, until they will fit into the procrustean beds of fixed rules, to the point where it is clear that all principles are empirical generalizations from the ways in which previous judgments of conduct have practically worked out. When this fact is apparent, these generalizations will be seen to be not fixed rules for deciding doubtful cases, but instrumentalities for their investigation, methods by which the net value of past experience is rendered available for present scrutiny of new perplexities. Then it will also follow that they are hypotheses to be tested and revised by their further working.[8] [8] Among contemporary moralists, Mr. G. E. Moore may be cited as almost alone in having the courage of the convictions shared by many. He insists that it is the true business of moral theory to enable men to arrive at precise and sure judgments in concrete cases of moral perplexity.
