👉 In the context of philosophy and meta-philosophy, an "immaterialised" concept is one that has been reduced to its essence or basis. It refers to a concept that has no physical existence or substance, as opposed to being materialized, which means to be physically present in the world. For example: 1. Materialism: The idea of atoms and molecules as the fundamental constituents of all matter. 2. Idealism: The belief in the existence of an ultimate reality beyond matter
