It is certainly true that religious life cannot attain a certain degree of intensity without implying a psychical exaltation not far removed from delirium. That is why the prophets, the founders of religions, the great saints, in a word, the men whose religious consciousness is exceptionally sensitive, very frequently give signs of an excessive nervousness that is even pathological: these physiological defects predestined them to great religious rôles. The ritual use of intoxicating liquors is to be explained in the same way.[714] Of course this does not mean that an ardent religious faith is necessarily the fruit of the drunkenness and mental derangement which accompany it; but as experience soon informed people of the similarities between the mentality of a delirious person and that of a seer, they sought to open a way to the second by artificially exciting the first. But if, for this reason, it may be said that religion is not without a certain delirium, it must be added that this delirium, if it has the causes which we have attributed to it, _is well-founded_. The images out of which it is made are not pure illusions like those the naturists and animists put at the basis of religion; they correspond to something in reality. Of course it is only natural that the moral forces they express should be unable to affect the human mind powerfully without pulling it outside itself and without plunging it into a state that may be called _ecstatic_, provided that the word be taken in its etymological sense ([Greek: ekstasis]); but it does not follow that they are imaginary. Quite on the contrary, the mental agitation they cause bears witness to their reality. It is merely one more proof that a very intense social life always does a sort of violence to the organism, as well as to the individual consciousness, which interferes with its normal functioning. Therefore it can last only a limited length of time.[715]
