.ce 20090331.00 .PP It may be too late, but perhaps it's still worthwhile to reflect on the limitations of the effort of my youth concerning the origin of doubt. At the time I wrote that essay its theme seemed to me to be the central issue of (my) existence, perhaps even the only one worth consideration. Today I see more broadly that, however important, it is only one of several, perhaps of many topics worthy of attention. .PP The most immediate, compelling and cogent comment is to recognize it as the most elaborate and ambitious of all sour-grapes declarations. That the doubt which I proclaimed was the essential compensation and cover for my despair, not so much, dass ich erkenne was die Welt im Innersten zusammen haelt, as Wenn es Goetter gaebe, wie hielte ich es aus kein Gott zu sein. Also gibt es keine Goetter. When I discovered myself incapable of universal, comprehensive knowledge, I declared that such knowledge was illusory. A monumental instance of sour grapes. (The same criticism, incidentally, is appropriate also to Die Kritik der reinen Vernunft, und Die Welt als Wille und Vorstellung.) One might ask whether resentment of ones cognitive failures might not be at the root of the kind of theoretical investigation in which I indulge. Such self-criticism might lead to an understanding at a deeper level of what it means to know. .PP The conceptual world, of course, is the world described by language. To disparage that world is to disparage language, and language will ultimately wreak its revenge for the disparagement. To say anything at all, I had to say it in words, and in the words of which I availed myself there would inhere the same deficiencies that I was trying to circumvent. I was contradicting myself: In positing ethical and esthetic consciousness as sources of doubt about the conceptual world, I was at one and the same time asserting the cogency of that which I proposed to doubt, unless I was able to convince myself and my reader that consciousness, ethical and esthetic, was somehow distinct from the conceptual world. Perhaps so, but in that case I shouldn't write about it. As soon as I wrote about it, it would become part of that world which I was denigrating. .PP Clearly, what was in order, if what I had in mind was to be communicated at all, was a different use of language, - or perhaps a different medium of communication altogether: an issue which raises the question: whether to some purposes, for some ends, communication is necessary, possible, or even desirable. .PP The issue: to what extent does my essay have the effect of suggesting, demonstrating or even inculcating a different style of thought, a different mode of awareness.
