But then the author has assigned a URI to two different resources,
which is prohibited by the URI specification. It's either a Web Page,
or it's the concept of some abstract thing, like love or hatred, or it
represents some physical object like a brick, but not all three. Not
any more than one.

So you have http://robustai.net/seth/ and it's your homepage. Fine.
You can put it in your RDF bookmark system. Now, you want to coin some
abstract entity that is defined by a view of that resource, for
example "Truth", so you use the URI http://robustai.net/seth/#Truth or
even http://robustai.net/seth/Truth as long as the latter is never
referred to as a Web Page. Even if it is, there isn't a problem,
thanks to contextualization - someone can call it a Web Page if they
want to - it won't break any of your programs.
