Compatibilism

Compatibilism, also known as "soft determinism" and most famously championed by Hume, is a theory which holds that free will and determinism are compatible. According to Hume, free will should not be understood as an absolute ability to have chosen differently under exactly the same inner and outer circumstances. Rather, it is a hypothetical ability to have chosen differently if one had been differently psychologically disposed by some different beliefs or desires. Hume also maintains that free acts are not uncaused (or mysteriously self-caused as Kant would have it) but caused by our choices as determined by our beliefs, desires, and by our characters. While a decision making process exists in Hume's determinism, this process is governed by a causal chain of events. For example, a person may make the decision to support Wikipedia, but that decision is determined by the conditions that existed prior to the decision being made.
