@Alan McDougall,
I'd agree about Hegel but find Wittgenstein hopelessly muddled. He is often accused of mysticism but never understood it, or never demonstrated that he did.
Btw, by my earlier comment about the voidness of phenomena being a first person report I didn't mean to suggest it was
my report. I haven't travelled so far worst luck.

But back to the topic. Heidegger's 'What is Metaphysics?' is worth a read. It was his inaugural lecture at the U. of Freiberg. In it he makes an important distinction between traditional metaphysics and mysticism, accusing metaphysics of dealing only with beings and never with Being. This, he says, is 'no mere mistake,' by which I presume he means that Being is a can of worms that metaphysicians are reluctant to open.
