Our error came from foolish self-sufficiency and pride. We thought (forsooth) that our mere human conceptions of contradiction were real. It has been granted to us (though we are but human still), to discover our error--there is no hot or cold, no light or dark, and no good or evil, all are, in a certain sense, and with certain limitations (if I may so express myself) the Aspects---- _At this point the bell rang and the papers had to be delivered up. Lambkin could not let his work go, however, without adding a few words to show what he might have done had time allowed. He wrote:--_ “No Time. Had intended examples--Success, Academic, Acrobatic, Agricultural, Aristocratic, Bacillic ... Yaroslavic, Zenobidic, etc. Historical cases examined, Biggar’s view, H. Unity, Univ. Consciousness, Amphodunissa,[22] Setxm [Illustration].” V. Lambkin on Sleep [_This little gem was written for the great Monograph on “Being,” which Lambkin never lived to complete. It was included, however, in his little volume of essays entitled “Rictus Almae Matris.” The careful footnotes, the fund of information, and the scholarly accuracy of the whole sketch are an example--(alas! the only one)--of what his full work would have been had he brought it to a conclusion. It is an admirable example of his manner in maturer years._] In sleep our faculties lie dormant.[23] We perceive nothing or almost nothing of our surroundings; and the deeper our slumber the more absolute is the barrier between ourselves and the outer world. The causes of this “Cessation of Consciousness” (as it has been admirably called by Professor M‘Obvy)[24] lie hidden from our most profound physiologists. It was once my privilege to meet the master of physical science who has rendered famous the University of Kreigenswald,[25] and I asked him what in his opinion was the cause of sleep. He answered, with that reverence which is the glory of the Teutonic mind, “It is in the dear secret of the All-wise Nature-mother preserved.” I have never forgotten those wise and weighty words.[26] Perhaps the nearest guess as to the nature of Sleep is to be discovered in the lectures of a brilliant but sometimes over-daring young scholar whom we all applaud in the chair of Psychology. “Sleep” (he says) “is the direct product of Brain Somnolence, which in its turn is the result of the need for Repose that every organism must experience after any specialised exertion.” I was present when this sentence was delivered, and I am not ashamed to add that I was one of those who heartily cheered the young speaker.[27] We may assert, then, that Science has nearly conquered this last stronghold of ignorance and superstition.[28]
