innumerable persistent misapprehensions. There have been
obstructionists in all times, not merely the lethargic masses, but
the moralists, the rationalizing theologians, and most of the
philosophers, all busily if unconsciously engaged in ratifying
existing ignorance and mistakes and discouraging creative thought.
Naturally, those who reassure us seem worthy of honor and respect.
Equally naturally those who puzzle us with disturbing criticisms and
invite us to change our ways are objects of suspicion and readily
discredited. Our personal discontent does not ordinarily extend to any
critical questioning of the general situation in which we find

can sometimes get quite pure and sparkling examples of all four kinds,
but commonly they are so confused and intermingled in our reverie as
