Question

Hello Rabbi,
The Rabbi distinguishes between liberty and freedom, and mentions many times that free choice can take place only when we have several different values and desires, and the act of decision/choosing occurs among them. But when we are dealing with a plain act of picking, then we do not really have choice.
I wanted to ask: what about our thoughts / consciousness / the "thinking self"? Is the act of thinking subject to a relatively full act of free choice? Or are thoughts also mainly the result of the brain's reflections, so that the act of choice occurs only when a thought clashes with a value—for example, whether to continue thinking forbidden thoughts in relation to a religious value. Only there does the act of choice take place, but not in the process of thinking itself. That is, the power of choice cannot generate new thoughts; rather, everything comes from the stirrings of our heart, and we only sort through the thoughts.
Of course, I agree that on all sides there is a situation in which the thoughts I think come from inner stirrings, but my question is whether the power of choice can create a thought about a new subject, and whether that is a significant part of the cases.
