An interesting post on Rigorous Intuition. I particularly like the quote from George Hanson, whom pretty clearly I need to read more of:
It is commonly assumed that there is a simple, objective correspondence between the signifier and the signified even thought they are separate entities. It is assumed that language is only a set of names for things, events, and concepts. These assumptions are incorrect, but few recognize the extent of the implications. This lies at the heart of deconstructionism, and magic.
