Seeking illustrations at large, we find this change typified in Hebrew history in the growing importance of the prophet over the judge, in the transition from a justification of conduct through bringing particular cases into conformity with existent laws, into that effected by personal right-mindedness enabling the individual to see the law in each case for himself. Profoundly as this changed conception of the relation between law and particular case affected moral life, it did not, among Semites, directly influence the logical sphere. With the Greeks, however, we find a continuous and marked departure from positive declaration of custom. We have assemblies meeting to discuss and dispute, and finally, upon the basis of the considerations thus brought to view, to decide. The man of counsel is set side by side with the man of deed. Odysseus was much experienced, not only because he knew the customs and ways of old, but even more because from the richness of his experience he could make the pregnant suggestion to meet the new crisis. It is hardly too much to say that it was the emphasis put by the Greek mind upon discussion--at first as preliminary to decision, and afterward to legislation--which generated logical theory. Discussion is thus an apt name for this attitude of thought. It is bringing various beliefs together; shaking one against another and tearing down their rigidity. It is conversation of thoughts; it is dialogue--the mother of dialectic in more than the etymological sense. No process is more recurrent in history than the transfer of operations carried on between different persons into the arena of the individual's own consciousness. The discussion which at first took place by bringing ideas from different persons into contact, by introducing them into the forum of competition, and by subjecting them to critical comparison and selective decision, finally became a habit of the individual with himself. He became a miniature social assemblage, in which pros and cons were brought into play struggling for the mastery--for final conclusion. In some such way we conceive reflection to be born.
