relation each thing bears to itself alone From Wikiquote, the free quote compendium
Identity is a concept related to various forms of definable entities; especially such entities as seem most subject to definition. Sciences, art, and technology involve ranges of knowledge, investigation and experimentation in terms of definite, defined, or definable entities, whereas religion, mysticism, and spirituality often deal with entities or notions that are recognized or explicitly declared to be beyond any definitions or concepts attainable by mortal minds.
