Transcendence

In philosophy, transcendental/transcendence, has three different but related primary meanings, all of them derived from the word's literal meaning (from Latin), of climbing or going beyond: one that originated in Ancient philosophy, one in Medieval philosophy and one in modern philosophy.

Original Definition
The first meaning, as part of the concept pair transcendence/immanence, is used primarily with reference to God's relation to the world and is particularly important in theology. Here transcendent means that God is completely outside of and beyond the world, as contrasted with the notion that God is manifested in the world. This meaning originates both in the Aristotelian view of God as the prime mover, a non-material self-consciousness that is outside of the world, and in the Jewish and Christian idea of God as a being outside of the world who created the world out of nothingness (creatio ex nihilo). In contrast, philosophies of immanence such as stoicism, Spinoza, Deleuze or pantheism maintains that God is manifested in and fully present in the world and the things in the world.

Medieval Usage
In the second meaning, which originated in Medieval philosophy, concepts are transcendental if they are broader than what falls within the Aristotelian categories that were used to organize reality conceptually. Primary examples of the transcendental are the existent (ens) and the characteristics, designated transcendentals, of unity, truth, and goodness.

"Transcendence" in Modern Philosophy
In modern philosophy, Kant gave transcendental a new, third meaning in his theory of knowledge, concerned with the conditions of possibility of knowledge itself. For him it meant knowledge about our cognitive faculty with regard to how objects are possible a priori. Something is transcendental if it plays a role in the way in which the mind "constitutes" objects and makes it possible for us to experience them as objects in the first place. Ordinary knowledge is knowledge of objects; transcendental knowledge is knowledge of how it is possible for us to experience those objects as objects. This is based on Kant's acceptance of David Hume's argument that certain general features of objects (e.g. persistence, causal relationships) cannot derive from the sense impressions we have of them. Kant argues that the mind must contribute those features and make it possible for us to experience objects as objects. In the central part of his Critique of Pure Reason, the "Transcendental Deduction of the Categories", Kant argues for a deep interconnection between the ability to have self-consciousness and the ability to experience a world of objects. Through a process of synthesis, the mind generates both the structure of objects and its own unity. For Kant, the "transcendent", as opposed to the "transcendental", is that which lies beyond what our faculty of knowledge can legitimately know. Hegel's counter-argument to Kant was that to know a boundary is also to be aware of what it bounds and as such what lies beyond it -- in other words, to have already transcended it.

In phenomenology, the "transcendent" is that which transcends our own consciousness - that which is objective rather than only a phenomenon of consciousness.

Colloquial Usage
In everyday language, "transcendence" means "going beyond", and "self-transcendence" means going beyond a prior form or state of oneself. Mystical experience is thought of as a particularly advanced state of self-transcendence, in which the sense of a separate self is abandoned.
