Let us say that there are 5 eatable items placed at the dining table during lunch that A is having. From the perspective of A, he has 5 choices and he can choose to eat whatever he wants to eat out of these items. In this way, A has limited free will.
However, the choice that A makes to eat something is governed by the thoughts coming out of A’s mind. These thoughts come out due to the laws of nature of which A has no control. Thoughts automatically come out of the mind, processed by the intellect and the decision is made. All these things happen automatically. In this way, free will is not really free as laws of nature govern both the origin & processing of thoughts.
