Actually Premise 1 is true.
I am beginning to think our apparent disagreement is but a matter of semantics. I think we may be understanding the connotation of the word “know” in two different ways.
In my understanding, if person P knows that K (where “K” is a proposition) then K is true. For if K is false, then P does not know that K.
For example, if you know that your son was at school at time T, then your son was at school at time T . It would not be possible for your son not to have been at school at time T. For if he had not been at school at time T, then you did not know that he was at school at time T.
As for statements about future events, it is no different. If you know now that you will attend a church on Sunday, then it is not possible for you not to attend a church on Sunday. For if you do not attend a church on Sunday, then you do not now know that you will attend a church on Sunday. You may intend to do so, but you do not know.
I remember when my son James was about four years old. I had trained him to come to me whenever I said, “Jamie, come here.” And he alway came when I said that. I might have told someone, "I know that Jamie will come to me, if I say ‘Jamie, come here.’ " But actually, I didn’t know. I thought I knew because he always came in the past when I uttered those words. But it is possible that he might have chosen not to obey. So sometimes we use the word “know” in a weaker sense. I should have said, "I am certain that Jamie will come to me, if I say, ‘Jamie,come here.’ " My certainty is a subjective state of mind, and not objective knowledge.
The words “I know that K” has the following meaning:
- I believe that K
- K is true
- I have sufficient evidence that K is true.
The third one is the difficult one. What constitutes “sufficient evidence”? But there is no question about the second one. If I know that K, then K is true.
It seems me that the actions of a free-will agent can be predicted in advance, but cannot be known—even by God, though He is in a much better position to correctly predict what a person will do than we, for being omniscient, He knows every thought and intention of every person.
In closing, I present a scriptural example in which God Himself thought Israel would do one thing, but she did the opposite. This example clearly shows that God did not know what Israel would chose. .
The LORD said to me in the days of King Josiah: “Have you seen what she did, that faithless one, Israel, how she went up on every high hill and under every green tree, and there played the whore? And I thought, ‘After she has done all this she will return to me,’ but she did not return, and her treacherous sister Judah saw it.” (Jeremiah 3:6,7)
And thus God’s omniscience does not include knowledge of what free-will agents will choose in the future.
