Omniscience refers to the state of having complete and unlimited knowledge, awareness, or understanding of all things. This concept is often associated with deities, such as God in various religious traditions, who are believed to know everything that has happened, is happening, and will happen. Omniscience implies not only knowledge of facts but also an understanding of thoughts, intentions, and the future. In philosophy, omniscience raises questions about free will and determinism. If a being is all-knowing, it challenges the idea that individuals can make independent choices. This topic is explored in various fields, including theology, ethics, and metaphysics, as scholars seek to understand the implications of such absolute knowledge.
