I find Goldin a little hard to understand. For instance, the following from his commentary on this topic 'If Not I for myself, Who Then?' ..."That is why one who does good is rewarded and one who transgresses is punished: for if our actions were determined by Heaven and not by ourselves, if man were compelled to do what he does, it would not be just to reward those who do good and to punish those who transgress (Aknin)". What is being said here, surely Heaven does not reward or punish. And what is 'just' can be viewed in many different ways and may not be a consequence of specific actions.
