FOURTH-CENTURY PHILOSOPHY 373 mined to make Humanity go its way without cringing to capricious gods and without sacrificing Free-Will. He condensed his gospel into four maxims: "God is not to be feared ; death cannot be felt ; the Good can be won ; all that we dread can be borne and conquered." Two great systems remained, more intellectual and less emotional : the Academy, which, after the death of its founder and Speusippus, turned from paradoxical meta- physics in the direction of a critical and sceptical eclec- ticism ; and the Lyceum or Peripatos, whose organisa- tion of knowledge formed the greatest intellectual feat of the age.
