FREE WILL – in detail
Free will is the ability to do what we want without any force or constrain. Free will makes it possible for us to make "our own" decisions, e.g. to either turn left or right, to go to work or not, etc. It is one of the biggest philosophical mysteries of all times.
It is the influence it has on what we see today that makes it a very important phenomenon, as, other than natural causes, everything that has ever happened or is happening to anybody or anything can be attributed to the capability of making free will decisions.
Basic philosophical argument against free will: Everything in the known universe is pre-determined, i.e. caused by earlier events, and thus, is predictable. If that is the case, how is it possible that decisions we make are not pre-determined?
With volumes written on the subject questioning, amongst other things, its existence (questioning which itself requires free will), with no conclusive end, the gist of how brain becomes capable of making free will decisions can be explained in just one sentence using DF analysis, which is as follows:
"It is VP's flexibility to judge and finalize solutions empowered by its wisdom, which is contributed by its capability of considering both, past and future data using B-ROM and thorough logic using LB, which gives mind the power of making free will decisions".
In detail: VP and LB are two entities designed to achieve common goals of survival and reproduction. They offer solutions using different ways of processing, in which VP's processing is based on its selection of contextual past data and/or future projections and LB's processing is based on thorough logical computations. Based on such partnership between them, VP has the wisdom to make judgement on which solution to finalize for execution, as other than considering past data and/or future projections, it also considers thorough logical processing provided by LB, thus providing best of both worlds solutions.
Additional to such wisdom, it is LB's dependence on VP to execute physical actions that gives it an upper hand, as, other than repetitive, all actions are guided by VP.
Based on the above, VP can choose whether to follow its own solution or LB's solution, and which one in the case of multiple accumulated solutions. Such flexibility offers VP the capability of "making" free will decisions. The freedom it offers is the freedom we perceive while making decisions.
