“Life is, in itself and forever, shipwreck. To be shipwrecked is not to drown. The poor human being, feeling himself sinking into the abyss, moves his arms to keep afloat. This movement of the arms which is his reaction against his own destruction, is culture — a swimming stroke.... But ten centuries of cultural continuity brings with it — among many advantages the great disadvantage that man believes himself safe, loses the feeling of shipwreck, and his culture proceeds to burden itself with parasitic and lymphatic matter. Some discontinuity must therefore intervene, in order that man may renew his feeling of peril, the substance of his life. All his life-saving equipment must fail, then his arms will once again move redeemingly.”
