I just finished Dr. Olson’s book Against Calvinism (It is really difficult to find time to read when you have a one year old). In appendix 1, Dr. Olson goes over several attempts by Calvinists to protect God’s character despite their theology. One particular argument caught my eye: the use of middle knowledge.
Roger Olson explains:
Molinism… is the belief that God possesses “middle knowledge” — knowledge of what any creature would do freely in any possible set of circumstances. The creature may possess libertarian freedom — freedom not compatible with determinism and able to do other than it does — but God knows what he or she wold do with that ability in an conceivable situation.
