To make whatever decision I, myself want to make.
free will
–noun
1. free and independent choice; voluntary decision: You took on the responsibility of your own free will.
2. Philosophy. the doctrine that the conduct of human beings expresses personal choice and is not simply determined by physical or divine forces.
I would like to emphasize the word "free". Are we "free" from God's omniscience?
Well, God seeing the future saw that Pharoh's decisions wouldn't benifit God's chosen people, God then decided to act. Free will does exist. It is a gift. Pharoh, at that moment, being defiant of the true God, got his free will taken away. But lets stay on the current topic.
No no, this is interesting. What purpose did it serve to harden the Pharaoh's heart (it still deals with predestination, as it is apparent that God intended to punish innocent Egyptians in the first place, thus he limited the Pharaoh's free will)?
There is not only one choice possible. There are infinite choices, but you can only choose one. Could have have chosen the other? Sure, but you didn't you chose this one. Its like choosing a spouse, (another poor example) today, you can choose several different mates to be with, however, you can only marry one, and it is completely up to you to decide.
This current thought pattern is too simple.
Why do you make a choice? Well, there are thousands of tiny things that affect what your decision may be, and you control none of those.
Say you come at a crossroads: you could go right or left. You would, ultimately, choose one. Why? Personal preference, past experience, etc. However, you will make one choice. you could have never made the other choice, not if that exact situation were repeated 1,000 times. This is because everything that drove you to make the choice you made would not have changed. There is no mythical power you draw from when you make a choice.
Or let's go with yours: you have a choice, a beautiful shallow girl or a plain thoughtful girl. Which do you choose? Preference and experience, of course. But seeing as how you're you, whichever girl you choose (no. 1 or no. 2) is the
only girl you could've chosen, because you're basing the choice based on your experience and your preferences. You would have never chosen the other girl, not with current said experience and preferences.
In other words, it is
physically possible to choose the other girl, but you never would've done so.
