The spiritual commons, the shared pool of tropes and correspondences and roles that unite the minds of disparate people, is an extremely valuable resource.  It keeps humans alive and sane. 

Sometimes, for one reason or another, you can’t thrive in the commons. Sometimes you need to define yourself (or something else) in your own terms, which may not seem coherent or meaningful to anyone else.  That’s OK.  We can, and must, accommodate that.  Thriving is important.  And who knows?  Maybe your private semiotics, or your category schemata, will turn out to be useful to people other than yourself.

I do a lot of that thing.  Really, I’m not knocking it.

…but it doesn’t make you brave.  It certainly doesn’t make you visionary.  It makes you a defector.  You are contributing to the destruction of a public good for private gain.
