Immanence
The nature of philosophical form and thought, both academic and non-academic, often is relegated to a distinction, by various degrees, of foundationalism/anti-foundationalism and transcendentalism/anti-transcendentalism.
Foundationalists observe a primitive boundary in and as the foundation itself from which distinctions arise.
Anti-Foundationalists observe a negation of the primitive boundaries from which distinctions arise.
Transcendentalists observe a movement beyond primitive boundaries from which distinctions arise.
Anti-Transcendentalists observe the maintainance of the primitive boundary from which distinctions arise.
This dichotomy of dichotomies, a fourfold structure, reveals approaches of attention as to what is percieved as a primitive boundary, an axiom or belief is many respects, thus effectively nullifying itself in many respects as what remains is the imananence of the distinction of the boundary.
The foundationalist in observing the primitive boundary effectively progresses such a boundary, by scaling it through dialogue and argumentation, with the anti-foundationalist.
The anti-foundationalisg is observing the primitive boundary as a distinction to be negated thus by negation reveals a primitive boundary upon which it pivots.
The transcendentalist in seek to move beyond the primitive boundary effectively establishes the movement beyond as the boundary itself, thus necessitating that which is transcended as necessary for transcendence which in turn nullifies transcendence by degree of necessity.
The anti-transcendentalist in seeking to observe the primitive boundary of distinctions present effectively nullifies its anti-transcendence by moving beyond transcendence.
What remains is the immanence of the primitive boundary, as the fourfold structure reveals a distinction of a primitive boundary that is neither foundational nor anti-foundational, neither transcendent nor anti-transcendent as the event of distinction reveals not just a primitive boundary, an axiom or belief in many respects, but the necessary event of such things to occur.
The immanence of distinction reveals itself as what occurs, be that occurence an abstraction or empirical reality, a thought or intuition, of the senses or deprived of said things. The mere occurence of any reality or unreality reveals the event of the distinction of each regardless thus by degree any truth or falsity cannot escape that simple state of being "just is" for what is not is but a distinction of what is by degree of contrast.
In these respects foundationalism is immanent, anti-foundationalism is immanent, transcendentalism is immanent, and anti-transcendentalism is immanent. By further degree any distinction of what is not immanent is immanent by degree of the distinction "not-immanent" being immanent.
What remains is immanence.
