"There is no correlation between material and spiritual misery. Only to the lowest and dullest levels of society can one preach the formula for all human happiness and wholeness as the well-named "animal ideal," a well-being that is little better than bovine. Hegel rightly wrote that the epochs of material well-being are blank pages in the history book, and Toynbee has shown that the challenge to mankind of environmentally and spiritually harsh and problematic conditions is often the incentive that awakens the creative energies of civilization."
