" The human mind is a product of the Pleistocene age, shaped by wildness that has all but disappeared. If we complete the destruction of nature, we will have succeeded in cutting ourselves off from the source of sanity itself. Hermetically sealed amidst our creations and bereft of those of the
Creation, the world then will reflect only the demented image of the mind imprisoned within itself. Can the mind doting on itself and its creations be sane? "
