This is the leading feature in M. Comte's conception of a regenerated society; and however much this ideal differs from that which is implied more or less confusedly in the negative philosophy of the last three centuries, we hold the amount of truth in the two to be about the same. M. Comte has got hold of half the truth, and the so-called liberal or revolutionary school possesses the other half; each sees what the other does not see, and seeing it exclusively, draws consequences from it which to the other appear mischievously absurd. It is, without doubt, the necessary condition of mankind to receive most of their opinions on the authority of those who have specially studied the matters to which they relate. The wisest can act on no other rule, on subjects with which they are not themselves thoroughly conversant; and the mass of mankind have always done the like on all the great subjects of thought and conduct, acting with implicit confidence on opinions of which they did not know, and were often incapable of understanding, the grounds, but on which as long as their natural guides were unanimous they fully relied, growing uncertain and sceptical only when these became divided, and teachers who as far as they could judge were equally competent, professed contradictory opinions. Any doctrines which come recommended by the nearly universal verdict of instructed minds will no doubt continue to be, as they have hitherto been, accepted without misgiving by the rest. The difference is, that with the wide diffusion of scientific education among the whole people, demanded by M. Comte, their faith, however implicit, would not be that of ignorance: it would not be the blind submission of dunces to men of knowledge, but the intelligent deference of those who know much, to those who know still more. It is those who have some knowledge of astronomy, not those who have none at all, who best appreciate how prodigiously more Lagrange or Laplace knew than themselves. This is what can be said in favour of M. Comte. On the contrary side it is to be said, that in order that this salutary ascendancy over opinion should be exercised by the most eminent thinkers, it is not necessary that they should be associated and organized. The ascendancy will come of itself when the unanimity is attained, without which it is neither desirable nor possible. It is because astronomers agree in their teaching that astronomy is trusted, and not because there is an Academy of Sciences or a Royal Society issuing decrees or passing resolutions. A constituted moral authority can only be required when the object is not merely to promulgate and diffuse principles of conduct, but to direct the detail of their application; to declare and inculcate, not duties, but each person's duty, as was attempted by the spiritual authority of the middle ages. From this extreme application of his principle M. Comte does not shrink. A function of this sort, no doubt, may often be very usefully discharged by individual members of the speculative class; but if entrusted to any organized body, would involve nothing less than a spiritual despotism. This however is what M. Comte really contemplated, though it would practically nullify that peremptory separation of the spiritual from the temporal power, which he justly deemed essential to a wholesome state of society. Those whom an irresistible public opinion invested with the right to dictate or control the acts of rulers, though without the means of backing their advice by force, would have all the real power of the temporal authorities, without their labours or their responsibilities. M. Comte would probably have answered that the temporal rulers, having the whole legal power in their hands, would certainly not pay to the spiritual authority more than a very limited obedience: which amounts to saying that the ideal form of society which he sets up, is only fit to be an ideal because it cannot possibly be realized.
