Tocqueville on Daas Torah

It has been shown that at times of general culture and equality the human mind consents only with reluctance to adopt dogmatic opinions and feels their necessity acutely only in spiritual matters. This proves, in the first place, that at such times religions ought more cautiously than at any other to confine themselves within their own precincts; for in seeking to extend their power beyond religious matters, they incur a risk of not being believed at all. The circle within which they seek to restrict the human intellect ought therefore to be carefully traced, and beyond its verge the mind should be left entirely free to its own guidance.

Mohammed professed to derive from Heaven, and has inserted in the Koran, not only religious doctrines, but political maxims, civil and criminal laws, and theories of science. The Gospel, on the contrary, speaks only of the general relations of men to God and to each other, beyond which it inculcates and imposes no point of faith. This alone, besides a thousand other reasons, would suffice to prove that the former of these religions will never long predominate in a cultivated and democratic age, while the latter is destined to retain its sway at these as at all other periods.

In continuation of this same inquiry I find that for religions to maintain their authority, humanly speaking, in democratic ages, not only must they confine themselves strictly within the circle of spiritual matters, but their power also will depend very much on the nature of the belief they inculcate, on the external forms they assume, and on the obligations they impose.
