Ordinary language discourse about TPC and TPP is always a very a subtle and illusive affair. It does not seem clear that ordinary language can capture with the right degree of precision what should be said and understood. There is always a margin for ambiguity and vagueness and hence an element of error which can be exploited dialectically to lead to apparent contradictions and amphibolies. This is the case for terms and propositions relating to spiritual development and realization. If propositions can appear contradictory (cf. the tension between detachment and integration) on the surface level this is in reality a manifestation of ordinary language attempting to capture something very precise.
An important point is that if there are a plurality of ordinary consciousnesses these manifestly exhibit their own particular characters and qualities and their own particular socio-historical relational network. This specificity and difference can be considered a major guiding principle in the development of TPC and TPP - and specially in the light of considering TPC and TPP as involving a kind of essential integration in communion with insight, calm and detachment.
Insightful detachment is very different from naive detachment. Insightful detachment performs a kind of regression and analysis to find the positive spiritual powers at work in the attachment which have become erroneously monolithically fixated with certain posterior determinations.
Another aspect of transcendental amnesia is forgetfulness that half of our total consciousness experience is spent in a state of dreaming during sleep. Why should one state be downgraded relative to another ? What does wakefulness mean from the point of view of dreaming ? Can lucid dreaming be considered a substantial step in the direction of peace, liberation and freedom ?
In TPC we have a situation in which reasoning, deduction, proof can be likened to how we teach or show somebody a dance or draw a figure in the air with our finger. The proof (or dialectic) is a self-revealing self-unfolding process which dissolves and is lost once any fixed proposition is settled upon independently, in itself. Cf. Sextus' statement "the skeptic is still inquiring" or the famous simile in a letter of Plato. Thus in treating of logic and computability and seeking for their ultimate source we exhibit a cyclic process.
Often what is wrong and harmful with many western spiritual traditions is not certain spiritual states or exercises involved, considered in their purity, but the harmful and erroneous conceptualizations and beliefs arbitrarily associated to them or establishing a feedback loop with them. As for western spiritual traditions, besides those that stand out such as the pythagorean, neo-pythagorean, middle platonic and neoplatonic schools and other schools of ancient Hellenic and Hellenistic philosophy (such as the Stoics and in particular Epictetus), and the Hellenic adaptation of Egyptian traditions in the Corpus Hermeticum, it a great tragedy that we no longer have access to the first-hand, authentic, original Western sources for much of the better elements of historical Christianity (for instance the Druidical, Chaldean, Syrian, Phoenician traditions or the secret teachings of the Eleusianian and Orphic mysteries). However there is still a wealth of information that can be gathered from Homer, the Homeric Hymns, Greek Theater and references found in Plato. A promising avenue of investigation (that we have already written about) seems to be to focus on ancient Iranian traditions as well a plausible widespread influence of (proto-)Mahayana Buddhism in the ancient world.
But let us recapitulate some principles of TPC and TPP.
Transcendental awareness of the present moment qua truly present. This requires "detachment" and "letting go of past and future " but such a present moment is a transcendental and revealed to be the "inner".
Transcendental awareness that this present moment being forgotten and unknown is a condition for ordinary consciousness and experience.
Transcendental awareness of temporality as a universal conditioner of experience and also transcendental awareness that forgetfulness of this aspect of temporarlity is itself a condition for ordinary consciousness and experience.
Transcendental awareness that thought is a distorting illusory screen which hides and distorts transcendental awareness of the pure present moment and awareness that forgetfulness of thought as it is in itself is a condition of ordinary experience.
Transcendental awareness of nature of the self, of the illusion of the self, perceived is such and that forgetfulness of this awareness of the self and its nature is a condition for ordinary experience.
Transcendental philosophical praxis involves overcoming, by skillful means, the above transcendental forgetfulness and the allaying of all illusions and distortions.
Consider the sobriety and circumspection and acumen of Hume and Kant as contrasted with subsequent German idealism (Fichte, Krause, Schelling). One error of such German idealism is taking the illusory individual self as a philosophical starting point rather than the super-individual transcendent self (which might be called a spiritual space - the 'we ourselves' of Plotinus - alhough there seems to have been some confused awareness of this state on the part of the said philosophers). In a sense the jhânas (which involve illumination) are a foundation of philosophy, or rather, they constitute a higher stage of TPC and TPP.
Thus TPC and TPP involve a preliminary ascent through transcendental awareness to the jhanas. The jhanas then are a foundation for further transcendental awareness and philosophical development as well as a foundation for even higher forms of consciousness. However there is a great danger of partial or imperfect realizations of the jhanas leading to faulty, incomplete or distorted philosophical views and systems. But it can be said safely that the jhanas allow great insight into the nature of reality and the correct view and assessment of philosophical concepts and systems.
Thus TPC and TPP can be seen as involving a cyclic process of ascent (through transcendent logical and phenomenological analysis) and then positing and deduction (conceptual unfolding and expression, even axiomatic-deductive expression, flowing from the illumination of achieved higher states of consciousness) which may be repeated many times (perhaps likened to a spiral). This can be compared to Plotinus' account of Platonic dialectic. We can say, broadly speaking, that the anagogic aspect o TPC is negative, analytic, "dissolving" in the style of Pyrrho or Nagarjuna or even Hegelian logic - ultimately a turning inward and detachment - while the second component is positive, constructive, deductive, outflowing.
It is curious and rather uncanny that I just found this passage from Krause:
The analytic-ascending part of science starts with those immediately certain recognitions, which we find in every consciousness, and through self-observation it proceeds steadily to higher recognitions until intellectual intuition is obtained, which has to happen according to this procedure if genuine insight into ultimate reality is possible for the human mind.TPC and TPP are strongly connected and the theory of anagogic virtues is important.
