Isnt this a preconceived idea itself?
But that’s not exactly my point, which is how do we tell if Eastern or whatever philosophy is valid? If you say that Eastern philosophy is about a thing, perceiving it, experiencing it directly, so then that’s the measure of truth in that philosophy.
I need not judge what you say on some external, possibly irrelevant measure, but by what you say is meaningful to you or the purpose of what you said. If you say you want to go to a certain place, then I judge according to the fact of you reaching that place, or not. If you tell me this is a tool for hammering nails, then I judged the tool according to what it is claimed to do.
Now so if that philosophy seek for something and it failed to attain that thing, what then do I say?
But if you say you have attained the thing sought for in your philosophy but then you only cannot explained what this is or that you cannot described your experiences of it, how do I know you are not lieing?
For I hold the belief, a preconceived idea if you like, that all humans experiences are common: what you experienced I can experience, and thus it is knowable and communicable to me. The language may be imperfect, but because I experienced the same experienced, I can correlate from the bits and pieces, and suggestion and allusions in your language to be able to understand you, even accurately.
(So does zen has such notions? such as of the validity or reliability of human senses? or of the possibility of language to convey meaning? and what is a lie and what is a truth?)
Further even if I give you the benefit that you have experienced something other-worldly, beyond description and mundane common everyday experiences, then at the least you should be able to tell me what you did to attain that state of “highest awareness”. If again you say you cannot tell me, then I really cannot know whether you are lieing or mad.
Again I think the best judgement of Eastern philosophy (or religion?) is to see its effects on people subscribing to it, and actually having faith in it, ie put to practice what you say you believed (which I do not think is a high proportion, given the senselessness of it all).
So lets look at China, at India. And for zen lets looked at Japan. What it is today is essentially a result of Westernisation. What is the contribution to zen to Japanese society and values and knowledge etc. What about specific individuals? Who are the zen masters - real ones and not fictional ones - and what are their life stories? Well you have studied Eastern philosophy, care to share some stories of these? Or maybe ILP members staying in these countries would like to share what they see in their societies, for good or bad, that can be traced to their philosophical beliefs. Or maybe you just share how has it “impacted” your thinking or “not thinking”. (BTW if the ends of Eastern philosophy is not thinking, then there is no need for it.)
There is wisdom - a intutively agreeable and understandable one - that the tree is known by its fruits.
(And I do not or unable to discern the same quality of ‘intuitive truth’ in Eastern philosophy.)
