The romantic corruption of the infinite here joins with the romantic corruption of conscience, the transformation of conscience from an inner check into an expansive emotion that I have already traced in Shaftesbury and Rousseau. But one should add that in some of its aspects this corruption of the idea of the infinite antedates the whole modern movement. At least the beginnings of it can be found in ancient Greece,--especially in that “delirious and diseased Greece” of which Joubert speaks--the Greece of the neo-Platonists. There is already in the neo-Platonic notion of the infinite a strong element of expansiveness. Aristotle and the older Greeks conceived of the infinite in this sense as bad. That something in human nature which is always reaching out for more--whether the more of sensation or of power or of knowledge--was, they held, to be strictly reined in and disciplined to the law of measure. All the furies lie in wait for the man who overextends himself. He is ripening for Nemesis. “Nothing too much.” “Think as a mortal.” “The half is better than the whole.” In his attitude towards man’s expansive self the Greek as a rule stands for mediation, and not like the more austere Christian, for renunciation. Yet Plato frequently and Aristotle at times mount from the humanistic to the religious level. One of the most impressive passages in philosophy is that in which Aristotle, perhaps the chief exponent of the law of measure, affirms that one who has really faced about and is moving towards the inner infinite needs no warning against excess: “We should not give heed,” he says, “to those who bid one think as a mortal, but so far as we can we should make ourselves immortal and do all with a view to a life in accord with the best Principle in us.”[177] (This Principle Aristotle goes on to say is a man’s true self.)
