Freedom implies the power or ability to do otherwise.
An Actor acts freely only if when she acts, it remains in her power to have done otherwise. He could have rendered the proposition that he did not reach Chicago by midnight false. If determinism is true then the conjunction of P0 and L entails P 2. If J had raised his hand at T, then P would be false 3. If 2, then if J could have raised his hand at T, J could have rendered P false 4.
