"Why do we look so far for solutions if we have some in our own history?"

I believe we had even much more solutions, but most have simply been wiped out. The celtic druids for example seemed to had a very interesting philosophy, but they were destroyed by the romans and the christians finished off, what was left, just like the germanic and slavic religions/philosophy systems. And since they had a tradition of vocal teaching and not writing down, we know allmost nothing for sure about them as most of it comes from christian chronists.

But the bits you still can find, are very interesting, I think.
