Youre confusing epistemology with ontology. While being preceeds cognition ontologically, being doesnt preceed cognition epistemologically. Thought comes first in regards to the order of knowing, but in regards to the order of being, being obviously comes first. Its facinating to see how men think that if only im allowed to have this one twisted concept, one twisting of the mind, one can deal with all other issues in life. That is futile and meaningless. Besides that your views are self negating.
I am not convinced you employ the term 'ontological' in the same sense that I do. To be clear, I am not referring to the ontological argument: that the theistic God exists because of the concept of him. I am referring to ontological Being as set against ontic being.
You fail to demarcate between Being and being. Rational, scientific and theistic thought has no conception of ontological Being. Indeed, the entire history of western thought overlooks, misunderstands and entirely fails to engage with the question of such Being.
Misappropriating this subtlety results in a lack of philosophical consideration.
As I have mentioned above in my argument, there is no objective 'existence' about which one can have 'knowledge'. Knowledge does not precede Being. That consciousness ontologically discloses 'things' (including itself) is the founding constituent of its 'existence.' Knowledge is not separate from these disclosures. Things are illuminated in their specificity and disclosed through Dasenic ontology. 'Knowledge' (as suggestive of a type disclosure) can modify the disclosure, but only at the height of poetic 'knowledge' is the ineffable infinity of disclosive potentiality hinted at.
I don't quite know what to make of your condescension, so I will move on to the conclusion of your post.
You say we cant account for the root of existence through thought YET use thought in refference to the root of existence in order to say that. If you can make a knowledgable statement about the root of existence, then its possible to know what you mean by "root of existence". If one could know nothing abot it you would not be able to make any sensical knowledgable statement about it directly or indirectly. So youre statement is itself a knowledgable statement through ones thoughts about the root of existence saying one cannot get at the root of existence through thought.
Your previous 'one must exist to deny his existence' Cartesian-esque cogito makes no definition of existence, rather clumsily assuming that it is inherently understood. Understand that the 'ahead-of-itself' falleness of consciousness away from its ontological root is not something about which it (consciousness) merely has 'knowledge.' It fundamentally IS consciousness. Consciouss IS 'Being-towards-fallen-from-root' just as it IS 'Being-towards-death.' The root of existence is disclosed by Dasein as unknowable by the very Being of Dasein. The issue is utterly not a case of 'knowing,' 'logic' 'reason' or 'contradiction.' Indeed, those categories as tools of debate arise from a consciousness which IS fallen into Being.
That consciousness IS fallen into being, and that consciousness flies towards 'the future' as a point at which its self-reflective nature can be combined with its past disclosed ‘facticity’ and thus 'grounded,' (
'Nebulous Pleasure horizonward will flee' - Baudelaire) means that positing a theistic 'other' is appealing (whether in affirmation or blasphemy.) The theistic God fixes consciousness in its flight and reveals its ontology. ‘God’ is an attempt by man to disclose his own consciousness as ‘virtuous’, ‘sinful,’ ‘clever', or simply 'there-as-something.' Blasphemy is an attempt by man to objectify God before him as a subject to be controlled. Blasphemy attempts to fix the ontology of God as object - for example a crucifix that one might masturbate over. The Satanist affirms strength (ontological fixity) in objectification (as does the Sadist). The theist affirms ontological fixity in the disclosed presence of a theistic, paternal God.
To restate: consciousness ontologically IS 'fallen-into-being' and discloses itself as such. That is, consciousness IS 'unable-to-reach-its-root-through-cognition' ('I think, therefore I am' makes no definition of the 'am') and IS 'Being-towards-death.' Coupled with consciousness' continuous flight toward the future (itself a disclosure of consciousness) in search of a grounding which can never come, this fundamental nature of Dasein results in the creation of Theism. As stated previously, for me what is important is the ontological impact of theism on Dasein. Or in the vernacular: the state of the believing breast.
Imagine every tenet of your reason, all your language, all of your thought negated. Past, present and future are ineffable. It is impossible to do so: how can one think what cannot be thought?' However, crudely: what would be left would be 'God;' The all. This is not the 'knowledge' of attempted applied reason but the ontological grounding of the IS of reason itself. The nature of the ALL is beyond the tenets of human thought and is truly mystical. One cannot describe it. One cannot comprehend it. It cannot be thought, for it is in the negation of thought. Consciousness shepherds the ALL into existence. When poetic, it does so very beautifully. However, to posit its single disclosure of a theistic God as BEING (crudely put) true, is actually blasphemous to the infinity of potentiality offered by the ineffable All.
(Wow that was some pseudy, probably pretentious stuff. It's quite possible that due to my atrocious communication I may be misunderstood or even not understood at all. I apologise. The medium is a little restrictive and I have not helped things by making assumptions on knowledge of terms that are defined elsewhere on this board.)
