Predeterminism is difficult to discuss because its simple definition can logically lead to a variety of similar, complex (and, perhaps, better defined) concepts in
metaphysics,
theology, and the philosophy of
free will. The term
predeterminism suggests not just a determining of all events, but the prior and deliberately conscious determining of all events (therefore done, presumably, by a conscious being). Due to this, predeterminism and the similar term
determinism are easily and often confused or associated with ideas ranging, for instance, from the
physicalist (and often scientific) notion of
causal determinism to even the theological (and often religious) notion of
predestination. A
secular example to try to illustrate predeterminism is that a fetus's future physical, emotional, and other personal characteristics as a matured human being may be considered "predetermined" by heredity, i.e. derived from a chain of events going back long before their eventual birth. However, one of the difficulties with defining predeterminism using this example is that the word
predetermine necessarily implies a conscious being "doing" the determining ahead of time. With regards to predetermined heredity, a conscious being (perhaps a genetic scientist) is presumed to be the one speculating on what the fetus's personal characteristics will turn out to be, for example, based on looking at the genomes of the fetus and its ancestors. If there were not this conscious entity, the scientist, then one could say merely that the fetus's characteristics are
determined by heredity, rather than
predetermined. Predeterminism necessarily implies, at the very least, a passive but all-knowing observer, if not an active planner, designer, or manipulator (of the fetus's personal characteristics). This basic scientific idea of hereditary determination, though, already fulfills the definition of
causal determinism, a metaphysical concept. While determinism usually refers to a
naturalistically explainable causality of events, predeterminism seems by definition to suggest a person or a "someone" who is controlling or planning the causality of events
before they occur and who then perhaps resides beyond the natural, causal universe. This creates a definitional conflict because predeterminism, by this understanding, logically leads to a belief in the existence of a conscious being who must determine
all actions and events in advance and who, possessing such seeming
omnipotence, almost certainly operates outside of the laws of nature. This conscious entity is probably, then, a being who is omnipotent as well as presumably
supernatural and
omniscient. The definitional confusion here is that there is already a name for this very concept:
predestination. Predestination asserts that a supremely powerful being has, in advance, fixed all events and outcomes in the universe; it is a famous doctrine of the
Calvinists in
Christian theology. Likewise, the doctrine of
fatalism already explicitly attributes all events and outcomes to the will of a (vaguer) higher power such as fate or destiny. Furthermore, in philosophic debates about the compatibility of
free will and
determinism, some argue that
predeterminism back to the origin of the universe is simply what philosophers mean by the more common term "determinism." Others have suggested that the term "
self-determination" be used to describe actions as merely "determined" by an agent's reasons, motives, and desires. When various interpretation of the word
predeterminism can be defined even better by other terms, such as the aforementioned determinism, predestination, or fatalism, then the definition of predeterminism itself appears awkward, unclear, and perhaps even worthless in terms of practical or philosophic discussion. ==R. E. Hobart==
