HE is free who lives as he likes; who is not subject either to compulsion, to restraint, or to violence; whose pursuits are unhindered, his desires successful, his aversions unincurred. Who, then, would wish to lead a wrong course of life? — "No one." Who would live deceived, prone to mistake, unjust, dissolute, discontented, dejected? — "No one." No wicked man, then, lives as he likes; therefore neither is he free. And who would live in sorrow, fear, envy, pity; with disappointed desires, and incurred aversions? — "No one." Do we then find any of the wicked exempt from sorrow, fear, disappointed desires, incurred aversions?—"Not one." Consequently, then, not free.
