How can we know what acts are due to free will and what are due to destiny?

Although I'm not sure science contends that the outcome is inherently random -- what it contends is that it cannot be predicted.

hi aedes


yes i should have said uncertain instead of random, since random might imply no general probability function, as in chaos. Confirmation of scientific prediction at that scale is only possible over a collection of events, which implies a range of space time rather than a single event.

I can understand there is uncertainty in the molecular world but how does that imply a range of space times

Every minute action you may take, can alter the outcome of your life

I personally think life changing moments are rare.

Know yourself and you will know the answer.

What was the question again?
I have pondered on the important decisions, in my life and the consequences it held for others.
The product of your desires and the children you love,can hinge on the most unimportant of events.My wife having a head ache one night and the grandchildren i love and adore would not exist.Is it fate, that they had to be my grandchildren? It feels like it,even if not true.

You are asking whether, whatever you chose to do, they would be your grandchildren. That is obviously false. If you had not chosen to do certain things, they would not have been your grandchildren. Isn't that obvious?
