At this juncture I cannot avoid trying to give a tentative and provisional expression to my own hypothesis concerning the origin of the bad conscience: it is difficult to make it fully appreciated, and it requires continuous meditation, attention, and digestion. I regard the bad conscience as the serious illness which man was bound to contract under the stress of the most radical change which he has ever experienced—that change, when he found himself finally imprisoned within the pale of society and of peace.
