CLEMENT:He had a tendency to go overboard on non-standard pseudo-
scientific ideas. He was the one who started the big push for what's
now called psionics. P-S-I-onics.His original example was an article
on something called Hieronymous machine; and I don't remember all its
details now except that it didn't work for me.

DISCH:One of the problems science fiction faces is that not only do we
not have ships flying to the stars yet, but interstellar travel is of
a different order of difficulty than travel to nearby planets. It
would take forever to go there at the speed of light.You have to
overcome Einstein's basic laws in order to have interstellar flight.
So he promised his readers -who want interstellar flight very much-
the defeat of Newton's and Einstein's laws of physics in something
like the Dean Drive, and also in promoting various kinds of balderdash
about psychic powers.
