Non-physical entity

A non-physical entity is an entity that lacks a physical/material body or characteristics. Non-physical entities may be considered hypothetical, e.g. deities of religions no longer conventionally believed in, and used as an example of an imaginary being in analytic philosophy, or they may refer to concepts whose existence is considered in philosophical argument, such as qualia. In esotericism and religions they may refer to gods, spirits, and so on, which either lack a body, or possess a subtle body only, and are generally considered belonging to a supra-physical plane of existence. In philosophy of mathematics, many people consider numbers, spaces, sets, and so forth to be existent and yet not physical.

Philosophy
