Final answer:
Libertarian free will is the belief that human actions are the result of free choices, making individuals morally responsible for their actions. Impossibilism, on the other hand, argues that free will is impossible due to the deterministic nature of actions.
Step-by-step explanation:
Under the concept of causal determinism, there are two opposing beliefs: libertarianism and impossibilism. Libertarian free will is the belief that human actions are not determined by prior causes but are instead the result of free choices that individuals have the ability to make. It argues that individuals have the power to act freely, making them morally responsible for their actions. On the other hand, impossibilism is the belief that free will is impossible because all actions are governed by natural laws and principles. According to this view, although individuals may have the sensation of freedom, their actions are ultimately determined by prior causes, rendering true free will impossible.
