persons there are, except the sexual nerve-centres, none which are compelled to act in this manner, in order to serve the purpose of the organism. Among the degenerate, on the contrary, particular morbidly excited brain-centres operate in this way, and the emotions of delight which accompany their explosive activity are more powerful than sexual feelings, in proportion as the brain-centres are more sensitive than the subordinate and more sluggish spinal centres. One may completely believe the assurances of great ecstatics, such as a St. Theresa, a Mohammed, an Ignatius Loyola, that the bliss accompanying their ecstatic visions is unlike anything earthly, and almost more than a mortal can bear. This latter statement proves that they were conscious of the sharp pain which accompanies nerve-action in overexcited brain-cells, and which, on careful analysis, may be distinguished in every very strong feeling of pleasure. The circumstance that the only normal organic sensation known to us which resembles that of ecstasy is the sexual feeling, explains the fact that ecstatics connect their ecstatic presentations by way of association with the idea of love, and describe the ecstasy itself as a kind of supernatural act of love, as a union of an ineffably high and pure sort with God or the Blessed Virgin. This drawing near to God and the saints is the natural result of a religious training, which begets the habit of looking on everything inexplicable as supernatural, and of bringing it into connection with the doctrines of faith.
