Definition: The term "anticonceptionist" refers to someone who believes in the existence of a pre-existing reality, or alternative world, that exists before our current one. Definition: An anticonceptionist generally holds that there is no real-world reality beyond what we perceive and experience; instead, the idea that there is some other reality with distinct characteristics and a predetermined structure exists. They often argue against the existence of a God (or gods) or other higher powers that they claim are necessary for human understanding. They also advocate for an eschatological view in which humans will eventually die and be resurrected as "ancient souls" to their higher realm, suggesting this is not just an illusion but an actual reality.
