Etymology

Origin of deterministic

determin(e) + -ist + -ic

Explanation

Do you believe that nothing is random, but instead that everything happens as a result of a past condition or cause? Then you're a fan of the deterministic theory. Having a deterministic view of why we do what we do means that you don't believe in free will. A deterministic philosophy says that every action we take was already pre-determined by past events, even when it feels like we're making choices. When it comes to deterministic thinkers, there's an overlap of philosophers and physicists who believe in a theory called determinism. Turn your deterministic thinking to the future, and you'll realize it's already been determined. Mind-blowing!
