I love your take on all this, Mike and your references are learned and useful. We've got a very useful dialogue going on here. It seems to me that Lacan is only elaborating on what Plato postulated around 600 BC re The Absolutes of Reality. I can't agree with you about Descartes - it's the cart before the horse syndrome - thinking is surely dependant on being. My consciousness of self is the only proof I have for my own existence. I'm very distrustful of Zen - it doesn't get us anywhere. Berkley is very difficult - he may be on to
something but of course he approaches it from a loaded perspective - i.e. and in facile terms, we're all living in the mind of God... Doesn't really help, does it?
With regards to mystagogues, (and they may be legion) I also have to say that personal experience countervails your comment - ' . . .remains forever outside the realm of the rational mind' unless you're referring exclusively to source. The whole point is that mystagogues do on rare often significant occasions take up fleeting residence in our lives. They/it seems to be able to interfere with the sub atomic world as a particle force with indications of intelligence and purpose. I will be bringing another new poem on the same theme to the next workshop which I suspect you will enjoy - it's called The Game of Rouns.
