I have pointed out another important use of the analytical intellect in its relation to the imagination. Since the imagination by itself gives unity but does not give reality, it is possible to discover whether a unification of life has reality only by subjecting it to the keenest analysis. Otherwise what we take to be wisdom may turn out to be only an empty dream. To take as wise something that is unreal is to fall into sophistry. For a man like Rousseau whose imagination was in its ultimate quality not ethical at all but overwhelmingly idyllic to set up as an inspired teacher was to become an arch-sophist. Whether or not he was sincere in his sophistry is a question which the emotionalist is very fond of discussing, but which the sensible person will dismiss as somewhat secondary. Sophistry of all kinds always has a powerful ally in man’s moral indolence. It is so pleasant to let one’s self go and at the same time deem one’s self on the way to wisdom. We need to keep in mind the special quality of Rousseau’s sophistry if we wish to understand a very extraordinary circumstance during the past century. During this period men were moving steadily towards the naturalistic level, where the law of cunning and the law of force prevail, and at the same time had the illusion--or at least multitudes had the illusion--that they were moving towards peace and brotherhood. The explanation is found in the endless tricks played upon the uncritical and still more upon the half-critical by the Arcadian imagination.
