in the case of its Greek framers, and of the habit of partizan loyalty in the case of its Roman adherents. In the arguments of Cotta, the unbelieving high-priest, we presumably have the doctrine of Cicero himself, [786] who in the Academica avows his admiration of Carneades's reasoning, and in the De Divinatione follows it, but was anchored by officialism to State usage. With his vacillating character, his forensic habit, and his genius for mere speech, he could not but betray his own lack of intellectual conviction; and such weakness as his found its natural support in the principle of use and wont, the practice and tradition of the commonwealth. On that footing he had it in him to boast like any pedigreed patrician of the historic religiousness of Rome, he himself the while being devoid of all confident religious belief. His rhetoric on the subject can hardly be otherwise estimated than as sheer hustings hypocrisy. Doubtless he gave philosophic colour to his practice by noting the hopeless conflict of the creeds of the positive sects, very much as in our own day conservative dialectic finds a ground for religious conformity in the miscarriages of the men of science. [787] But Cicero does not seem even to have had a religious sentiment to cover the nakedness of his political opportunism. Not only does he in the Tusculan Disputations put aside in the Platonic fashion all the Homeric tales which anthropomorphize and discredit the Gods; [788] but in his treatise On Divination he shows an absolute disbelief in all the recognized practices, including the augury which he himself officially practised; and his sole excuse is that they are to be retained "on account of popular opinion and of their great public utility." [789] As to prodigies, he puts in germ the argument later made famous by Hume: either the thing could happen (in the course of nature) or it could not; if it could not, the story is false; if it could, non esse mirandum--there is no miracle. [790] In his countless private letters, again, he shows not a trace of religious feeling, [791] or even of interest in the questions which in his treatises he declares to be of the first importance. [792] Even the doctrine of immortality, to which he repeatedly returns, seems to have been for him, as for so many Christians since, only a forensic theme, never a source of the private consolation he ascribed to it. [793] In Cicero's case, in fine, we reach the conclusion that either the noted inconstancy of his character pervaded all his thinking, or that his gift for mere utterance, and his demoralizing career as an advocate, overbore in him all sincere reflection. But, indeed, the practical subversion of all rational ethic in the public life of late republican Rome, wherein men claimed to be free and self-governing, yet lived by oppressing the rest of the world, was on all hands fatal to the moral rectitude which inspires a critical philosophy.
