K.S. Guthrie, Plotinus' Philosophy: "His position on free will is almost exactly that of Kant. Virtue and the motion of the soul in the intelligible realm are free; but the soul's deeds in the world are part of the law of continuity. Plotinus has no taste for the crude predestination of fatalism, and like immoral doctrines. . . . The soul is, in respect to her three lowest faculties, which belong to the World Order, rigidly conditioned: yet in the higher self is as free as self-existence can make it; and the soul will therefore be free exactly according as to whether she identifies herself with her higher or lower faculties. Man is therefore a slave of fortune when his reason has identified itself with his sense world, but free when his reason has identified itself with his individual Nous, turning all things to intellect."
