And in general it is always a hazardous thing to attempt to place a new foundation under a finished structure. Moreover, how should a religion require the suffrage of a philosophy? It has everything upon its side—revelation, tradition, miracles, prophecies, the protection of the government, the highest rank, as is due to the truth, the consent and reverence of all, a thousand temples in which it is proclaimed and practised, bands of sworn priests, and, what is more than all, the invaluable privilege of being allowed to imprint its doctrines on the mind at the tender age of childhood, whereby they became almost like innate ideas. With such wealth of means at its disposal, still to desire the assent of poor philosophers it must be more covetous, or to care about their contradiction it must be more fearful, than seems to be compatible with a good conscience. To the distinction established above between metaphysics of the first and of the second kind, we have yet to add the following:—A system of the first kind, thus a philosophy, makes the claim, and has therefore the obligation, in everything that it says, _sensu stricto et proprio_, to be true, for it appeals to thought and conviction. A religion, on the other hand, being intended for the innumerable multitude who, since they are incapable of examination and thought, would never comprehend the profoundest and most difficult truths _sensu proprio_, has only the obligation to be true _sensu allegorico_. Truth cannot appear naked before the people. A symptom of this _allegorical_ nature of religions is the _mysteries_ which are to be found perhaps in them all, certain dogmas which cannot even be distinctly thought, not to speak of being literally true. Indeed, perhaps it might be asserted that some absolute contradictions, some actual absurdities, are an essential ingredient in a complete religion, for these are just the stamp of its allegorical nature, and the only adequate means of making the ordinary mind and the uncultured understanding _feel_ what would be incomprehensible to it, that religion has ultimately to do with quite a different order of things, with an order of _things in themselves_, in the presence of which the laws of this phenomenal world, in conformity with which it must speak, vanish; and that therefore not only the contradictory but also the comprehensible dogmas are really only allegories and accommodations to the human power of comprehension. It seems to me that it was in this spirit that Augustine and even Luther adhered to the mysteries of Christianity in opposition to Pelagianism, which sought to reduce everything to the dull level of comprehensibility. From this point of view it is also conceivable how Tertullian could say in all seriousness: “_Prorsus credibile est, quia ineptum est: ... certum est, quia impossibile_” (_De Carne Christi_, c. 5). This _allegorical_ nature of religions makes them independent of the
