Paging A.E. van Vogt

I read this and thought of A.E. van Vogt. Along with his various "supermen" (the Slans, the Players of Null "A", etc.), he also came up with "Nexialism" in the "Space Beagle" tales. Writing at that time he saw that we were accumulating more and more knowledge...with the problem that people were becoming more and more specialized...and knowing less and less about "everything else".
