Do we have free will?
It is a common notion that humans inherently have free. But do we really? see for instance how a person became a sexual offender due to a brain tumor, this and another case can be found on video (video included) here. Also it has been shown that people decide to move only after their brain’s motor areas prepare for a movement.
But even more intriguing is the fact that a personality can change drastically due to various reasons . Chemicals can alter our perception of the world, behavior, feelings, intelligence, and eventually our decision making. Knowing all this, how could we ever claim to have free will? To what extent is it an illusion? And what meaning is there to our “personality” if it can be changed by external means?
Oftentimes, religious philosophers claim that our soul goes to heaven or hell or somewhere else. There is no way to counter the claim that a non-physical soul exists, but if this soul has no inherent memory, no real control of it’s actions, and no perception of the world – all actions are performed physically in the brain – then what does it have? And what interest do we have in it’s endeavors post vite?
