Stefan Weckbach,
Thank you for the constructive opinion. We just differ regarding freewill; to me, freewill is just the capability to select from allowed actions; so computers have freewill. There is only a slight difference between a deterministic event and and a freewill event. Freewill is possible just because of the deterministic nature of the action selected using freewill. In a non-deterministic world, freewill is impossible.
Quoting you, "I don't agree with you that you have explained how free will can come into play for the course of events in a cosmos". Here I think there is a slight misunderstanding. Freewill has no role in deciding the course of events in the cosmos. Whether freewill emerges or not, the course of events in the cosmos as a whole will be the same. Only that, during the course of of events, the environment invariably passes through a period suitable for freewill to emerge, and because of the deterministic nature of 'actions', freewill does arise.
Humans have freewill (the capability to select from allowed actions); our freewill actions does not at all affect the course of events in the Cosmos. Whatever we do, humans and all life forms will perish within a few billion years.
I will be going through your essay soon.
