Whilst perusing metafilter I found this speech by Philip K. Dick that was scheduled but never given.

I tend to be equivocal about whether I like Philip K. Dick’s books. Some of them really make me quite uncomfortable, and I can’t say that I really think he is a good writer. Despite this, I think he is the most important science fiction author, and perhaps the most important fiction author of the last half century (whom I’ve read, which is admittedly not very many). If you have read some of his work, you will know what I’m talking about.

In any case the speech is a good read and I encourage you to check it out.
