The further you go the wider the scope of something like a reduction of the key elements of experiencing to what is effectively phenomenality. This is perhaps a slightly dangerous magic, but is it really a reduction? Is anything changed? It is digging into certain assumptions which appear to have no more grounds than themselves. They are circular and therefore not anchored to anything. You can push them, these categories that have always been taken for granted, a little out from their normal course. The light falls differently on them, they no longer mean what they used to. But nothing has changed, everything is merely more itself.
