Ok, I'm glad that you think I've understood.<br>
<br>
Note that I'm not agreeing with it, in fact I think it's about as wrong as could be, but stating clearly what something is, is necessary before you can properly critique it, and in the past I hadn't much of a clue as to what you were actually claiming.<br>
<br>
I have some suspicions about your understanding of Lehar's theory, but haven't yet read enough of his stuff to be sure (it does make sense, as far as I've got). When I get round to it, I'll return to that.<br></blockquote></div></div><div dir="auto"><br></div><div dir="auto">From having corresponded and conversed with Brent on his ideas and way of approaching the problems of consciousness for many years I think I can shed some light on his theories.</div><div dir="auto"><br></div><div dir="auto">Though he often describes things in his own terms, Brent's thinking on this is not as uncommon as you might think.
