Quote by Arthur Schopenhauer

“After these numerous passages from the poets, I may now be permitted to express myself by a metaphor. Life and dreams are leaves of one and the same book. The systematic reading is real life, but when the actual reading hour (the day) has come to an end, and we have the period of recreation, we often continue idly to thumb over the leaves, and turn to a page here and there without method or connexion. We sometimes turn up a page we have already read, at others one still unknown to us, but always from the same book. Such an isolated page is, of course, not connected with a consistent reading and study of the book, yet it is not so very inferior thereto, if we note that the whole of the consistent perusal begins and ends also on the spur of the moment, and can therefore be regarded merely as a larger single page. Thus, although individual dreams are marked off from real life by the fact that they do not fit into the continuity of experience that runs constantly through life, and waking up indicates this difference, yet that very continuity of experience belongs to real life as its form, and the dream can likewise point to a continuity in itself. Now if we assume a standpoint of judgement external to both, we find no distinct difference in their nature, and are forced to concede to the poets that life is a long dream.”
