Out on the edge
you see all kinds of things
you can’t see from the center.
Big, undreamed-of things -
the people on the edge
see them first.
~ Kurt Vonnegut

I am an agnotologist, no doubt.  That is to say, I am fascinated with all that we do not know, with the gray areas and uncertainties of life, death, and everything.  Agnostic = Doesn't Know.  Agnotology = Study of Ignorance.  Science depends on us being very clear about what we do not know yet, so that we can devise ways to try to find out.

Without deviation from the norm,
progress is not possible.
