Corruptio boni: An alternative to the privation theory of evil.

The classic 'privation theory' of evil defines evil as an absence (or 'privation') of a good that ought to obtain. Despite its historical importance, privation theory is faced with a number of serious difficulties. I outline two of these difficulties and argue that they continue to pose a threat. I then present 'corruption theory', an alternative theory of evil reconstructed from some of Augustine's writings on the subject. I argue that this theory shares the strengths of privation theory, while evading its problems. [ABSTRACT FROM AUTHOR]
