Free will and determinism are incompatible for the reason that one cannot exist in the Universe with the other. If a person has the ability to make their own day-to-day decisions, their action could be classified under the principles of determinism or those of free will. For example, X (X being a person) woke up in the morning and decided to take the day off to drive their new car instead of going to work, is an example of a person exercising either free will or determinism. This action was completely the choice of X, who could have chosen to go to work or possibly not even to get out of bed, but if this was an act of determinism or free will depends on the abilities that X has. It is possible that X could have been creating the future as it was determined to be by the laws of nature and the set past. On the other hand, if X were gifted with the ability to control the effects of nature and the past on their decision, the action of X would prove to be an act of free will. Determinism and free will can only occupy one necessary principle of the Universe, therefore if one proves true in the Universe; the ideas held by the other are automatically false, ultimately, proving the presence of both ideas impossible in the same Universe. According to the principles of determinism, every action in the Universe is governed by the laws of nature (assuming that the laws of nature are all true) and affected by events from the past. This idea opens the doors to the possibility of predicting the future or present actions of everything in the Universe. Determinism cannot exist if an act of complete randomness occurs in the universe. This is because determinism is the theory that every action in the universe can be predicted, nothing can exist without being affected by any scientific laws of nature, and it is impossible for an act to occur without feeling any affect from the past. With this idea, the future is constantly determined by events in the imm...
