What is all-knowing?

All-knowing, or omniscient, is a term used to describe a being or entity that has complete and unlimited knowledge of all things. It is commonly associated with the concept of God or a divine being who has the ability to know everything that has happened, is happening or will happen in the future.

In philosophy and theology, the concept of all-knowing is usually seen as a necessary attribute of an all-powerful and perfect God. However, the idea of all-knowing is also explored in other areas such as science fiction, where characters or entities with this ability are often depicted as all-seeing and all-knowing beings who can see beyond time and space.

From a practical standpoint, the concept of all-knowing raises questions about free will, determinism, and the nature of knowledge itself. It also raises ethical questions such as the limits of surveillance and privacy, and the responsibilities of those who possess great knowledge and power.
