The joyous necessity of the dream experience has been embodied by the Greeks in their Apollo: Apollo, the god of all plastic energies, is at the same time the soothsaying god, He, who (as the etymology of the name indicates) is the "shining one," the deity of light, is also ruler over the beautiful illusion of the inner world of fantasy. [...] But we must also include in our image of Apollo that delicate boundary which the dream image must not overstep lest it have a pathological effect [...] We must keep in mind the measured restraint, the freedom from the wilder emotions, that calm of the sculptor god. His eye must be "sunlike," as befits his origin; even when it is angry and distempered it is still hallowed by beautiful illusion [...] (translated by Walter Kaufmann)
[...] Schopenhauer has depicted for us the tremendous terror which seizes man when he is suddenly dumbfounded by the cognitive form of phenomena because the principle of sufficient reason, in some one of its manifestations, seems to suffer an exception. If we add to this terror the blissful ecstasy that wells from the innermost depths of man, indeed of nature, at this collapse of the principium individuationis, we steal a glimpse into the nature of the Dionysian, which is brought home to us most intimately by the analogy of intoxication.

Even under the influence of the narcotic draught, of which songs of all primitive men and peoples speak, or with the potent coming of spring that penetrates all nature with joy, these Dionysian emotions awake, and as they grow in intensity everything subjective vanishes into complete self-forgetfulness. In the German Middle Ages, too, singing and dancing crowds, ever increasing in number, whirled themselves from place to place under this same Dionysian impulse. [...] There are some who, from obtuseness or lack of experience, turn away from such phenomena as from "folk-diseases," with contempt or pity born of consciousness of their own "healthy-mindedness." But of course such poor wretches have no idea how corpselike and ghostly their so-called "healthy-mindedness" looks when the glowing life of the Dionysian revelers roars past them.
