I couldn't answer before because of the five post limit in the first day of a new member.
Here it is shown the free will context for Stephen Hawking's comment I posted:
On free will and determinism
"I have noticed even people who claim everything is predestined and that we can do nothing to change it look before they cross the road."
The question of free will has long been a mainstay of philosophy and science, and it's a topic Hawking visited from a scientific point of view in his essay Is Everything Determined from his book Black Holes and Baby Universes and Other Essays, first published in 1993. It's the origin of this quotation. The next line is less-frequently cited, however: "Maybe it's just that those who don't look don't survive to tell the tale."
Hawking touches on a grand unified theory of science, quantum mechanics, natural selection, DNA, the complexity of the human brain and fluid dynamics in particular before arguing that assuming that we have free will is the safest course of action.
It is an extract of a page explaining the context of the more known Stephen Hawking's quotes:

I think the right question is on how much free will we have. May be in some circumstances we are totally conditioned with no possibility for a choice and in other ones we have complete freedom to decide and be totally responsible for our actions.
