Libertarians support the view that people have free will and so we are free to make moral decisions. For a Libertarian, the key evidence for this is the act of decision making in our daily lives.

Humans are unique in this way and it is this which is called the moral self. Libertarians are dualists believing that the human mind is separate from the physical world. It is because of this that our reason and autonomy, our moral self, can transcend over other causal determinants. Kant argues that by applying reason to decisions we can escape any authority from cause and effect or desires and emotions, we are the agents of our own decisions.

He argued that all physical objects have an essence that
