  So even if it is true that evil is a privation, this does not have as a consequence that God is not the author of sin. Given that what is positively willed by God is a sufficient condition for the existence of the evil state of affairs, in virtue of willing what is positive in some state of affairs, God is also the author of what is privative in that state of affairs.  [A similar early critique is found at A.6.3.544].
