I will examine (in section II) the attempts of Molina and Suarez to explain how God can have and then (in section III) the middle knowledge; account recently offered by Alvin Plantinga, who has reinvented the theory of middle knowledge. Two objections to my position will be discussed in section IV. The idea of middle knowledge emerges in recent discussion because of its philosophical chiefly to the second question relevance that I shall dis? is whether God could have made free cuss, which creatures who would always have freely done right.

QUARTERLY

I In the twenty-third chapter of the first book of Samuel it is written that after David had rescued and the Jewish city of Keilah from the Philistines, settled his men there, Saul made plans to besiege David Keilah in order to capture David. When heard of Saul's plans, he consulted God by means of of

And the Lord replied, "They will surrender David his men from evacuated you." Thereupon out in with the result that hid the and Keilah, hills, to besiege him Saul did not have the opportunity in Keilah, did not have and the men of Keilah occasion to betray him to Saul. (I Samuel 23:1 -14,
