You are entirely welcome Rev. (I am sure I speak for Jim as well!)  :-)

The world is a strange place and thinking about it is well known to cause headaches in untold degrees and of untold types. Not thinking about it causes far worse maladies, not only in individual heads, but in cliques, cadres, factions and entire societies. History teems with examples of societies that began with great spirits and great minds that did great things. And then? Well, let's think of more cheerful matters, such as you might read in Kipling's "Gods of the Copybook Headings".  Not that he himself was consciously better than a product of his times.

Strangely, certain heads seem... I don't quite know... they don't get the headaches, but although they sometimes are very intelligent people, they seem immune to the siren song of the unexplained, unachieved,  or uncomprehended. Is it because they are in some sense tone deaf? Or simply so competent at concentrating on what they know and understand that the call of the unknown has no attraction? Society has need of them, in fact more of them than the explorers, puzzlers, creaters and dreamers, without whom the Machine eventually would stop. The competent, headacheless, are the Machine.

And now, I think I am getting a headache...

Thanks anyway!
