Indeed, if a chief question does remain: how is the power to think possible? - The power to think right and left, before and without, with and above experience? then it does not take a deduction to prove the genealogical priority of language.
For me, the historical and genealogical library is the one I use. I'm working on, I'll say, it's a time travel novel. I haven't written very much of it. That's the dirty secret of the Cullman center: The writers don't write their fiction there, they just do their research.

Your soul is a dark forest. But the trees are of a particular species, they are genealogical trees.
Indeed optimists rather than defeatists have produced the results for which serious genealogical research is best known.
