- The “Deist” God has it’s origin in the same holy books and religious traditions as all the theist Gods. It’s just that, when Deists realized how untenable it was to assert belief in something for which there was no good evidence (and for which there was plenty of counter evidence), they decided to argue for an impersonal and undetectable creator God rather than abandoning their faith all together [“Deism gained prominence among intellectuals during the Age of Enlightenment, especially in Britain, France, Germany, and the United States. Typically, these had been raised as Christians and believed in one God, but they had become disenchanted with organized religion and orthodox teachings such as the Trinity, Biblical inerrancy, and the supernatural interpretation of events, such as miracles.”]. Which is to say that if we can dismiss all the theist concepts of God as the product of ignorant superstitions, we can dismiss the Deist God for exactly the same reason, despite all the pseudo-intellectual gloss that has been applied to the underlying concept over the years.
- Speaking of pseudo-intellectual gloss, every single argument in favor of there being a Deist God is based in an (or “God of the Gaps”) fallacy. Whether it be the so-called (a.k.a. the Argument from Design) argument, the , the Argument, or what have you, they all basically claim that since we [supposedly] cannot explain some facet of the universe, the only possible explanation is a supernatural creator who exists outside of time and space and is somehow able to interact with matter and energy despite not being composed of either. Aside from the fact that we actually can now explain many of the things that used to be inexplicable (the theory of Evolution by Natural Selection, for example, now perfectly explains the apparent design in the natural world), the lack of an explanation cannot, in itself, be evidence of some other explanation for which there is no evidence. Argument
- Aside from being wholly irrelevant and unnecessary, the Deist God is also, by definition, wholly incapable of being detected. Which is to say that, even if there were such a being, it wouldn’t matter if we did explore the entire universe since such a God would not be able to be found.
