Robert Kane Libertarianism

Author Robert Kane has a libertarian view on free will. He cites his reasons such as the garden of forking paths where every decision made by a person brings that person on a new path therefor forking from the old path. This means that it is possible a person could have chosen otherwise and gone on a different path if a different decision had been made. The alternate argument, for determinism, is that every decision has already been made and there is no garden of forking paths, just a straight line and everything that happens is meant to happen. Another major argument Kane uses is the argument of Ultimate Responsibility, which in short means that a person shall not be held completely responsible for something unless they are the ultimate author

of the action or thing. By ultimate author, I mean the problem has derived only from the actions of this one person and there is no one else or nothing else that can possibly be blamed.
Kane’s garden of forking paths (or Alternate Possibilities) theory completely contradicts the determinist theory of a straight path and all the events on that path are destined to occur because of the laws of nature and past events that could affect the line. An example of this would be if Alex found a lanyard, with a room key, a mail key, Marist ID with the name Kyle Hugs and forty dollars tucked inside the card holder.
Pharagraph 3,
There are some objections and problems with the libertarian view on free will. Kane mentions that compatibilists argue that “libertarian free will is unnecessary because we can have all the freedoms wroth wanting, even if determinism is true.” (Kane, 9)
