Hi,
MT: Nor should the world have need to validate itself.
NS: I would have thought a man of the mirage producing desert, such as your parched self, would be accustomed to the necessity of validation when confronted with appearances? Or, is any opportunity to fish too important to risk inquiry?
MT: especially if it does not really exist.
NS: Well now, “real existence” is what “inquiring minds” want to know, and what “true believers” fear to dis-cover.
MT: does little to confirm that indeed, nothing exists other than as a subjective idea based upon the ability to comprehend such nothingness.
NS: The physicists might protest that experimental objectivity confirms their subjective theories. But, you are in the main correct, that philosophers are in the business of interrogating/constructing/destructing “ideas.” What the Idealist (epistemologist & metaphysician) asks is how can (concrete & abstract) objects exist independent of ideation? The answer is that there is no ‘known’ example of it ever happening.

So, can there be, ‘in theory,’ an object (e.g. world) existing independent of anyone’s perception or conception of it? Yes, in theory, it is possible. But, 1. the redundancy (exact copy & authentic object) is clearly unnecessary, and 2. it is speculative to the max. Why stop at one unknown ‘authentic model,’ why not millions, why not postulate the existence of All unsupported, and imagined, possibilities as being ‘out there’ somewhere?
MT: How can one lose something (our cherry) that never existed without existence existing to confirm our own existence to begin with, providing we presume there was a beginning, of course.
NS: The appearance is not in question, but rather it’s substantial reality. A mirage “exists” as an apparition, but not as an actual object perceived. There is the ‘idea’ of a world, and a Cecil centered in it, no question. But, is there any such objects existent independent of the mental construct? Isn’t it possible that a dream could imagine a world with a Cecil centered in it, talking to a unicorn, but without any corresponding reality independent of a mind’s dreamt imaginings?
MT: There can be nothingness without the opposition confirming the existence of no thing. As darkness confirms the existence of light,
NS: That the construction of a house of cards necessitates opposing cards depending upon their opposite in order to stand, in no way supports the reality of the “house” itself. To the contrary, it lends support to the unreality of such an object. The Buddhists call this, “co-dependant arising.” I.e. if no object has any reality of its own to stand on, but can only appear to stand by virtue of leaning against another un-self-supporting object, then anything these objects comprise must itself be fundamentally unreal. IOW, build a building with imaginary bricks, and you’ll get an imaginary building every damn time.
MT: Does this comment exist in mind only or within the Lankavatara Sutra... or on your post-it-note?
NS: Note, sutra, my writing it, your reading it, the ideas of these, and the conceived mind that holds all of them, are all illusory objects.
”In Zen there is really nothing to grasp onto.”
MT: Are not those very words really objects and not merely efforts to describe what is always here?
NS: “Efforts” too are (insubstantial & imagined) “objects.”
”Knowledge of things is not in the things, and cannot proceed out of them. It proceeds from thee, and is indeed thine own nature.” (Johann Fichte, philosopher)
