the system of rewards and punishments (pr. 1). Boethius describes the flight of Imagination through the planetary spheres till it reaches heaven itself (met. 1). The good are strong, but the wicked are powerless, having no real existence (pr. 2). Tyrants are chastised by their own passions (met. 2). Virtue secures reward; but the wicked lose even their human nature, and become as mere beasts (pr. 3). Consider the enchantments of Circe, though these merely affected the outward form (met. 4). The wicked are thrice wretched; they _will_ to do evil, they _can_ do evil, and they actually _do_ it. Virtue is its own reward; so that the wicked should excite our pity (pr. 4). Here follows a poem on the folly of war (met. 4). Boethius inquires why the good suffer (pr. 5). Philosophy reminds him that the motions of the stars are inexplicable to one who does not understand astronomy (met. 5). She explains the difference between Providence and Destiny (pr. 6). In all nature we see concord, due to controlling Love (met. 6). All fortune is good; for punishment is beneficial (pr. 7). The labours of Hercules afford us an example of endurance (met. 7).
