cheek, the Potterites have taken Christianity and watered it down to suit
themselves, till they've produced a form of Potterism which they call by
its name; but they wouldn't know the real thing if they saw it.... The
Pharisees were Potterites....'

The others listened to Juke on religious Potterism tolerantly. None of
them (with the doubtful exception of Johnny, who had not entirely made up
his mind) believed in religion; they were quite prepared to agree that
most of its current forms were soaked in Potterism, but they could not be
expected to care, as Juke did.

Gideon said he had heard a dreadful band on the beach, and heard a
dreadful fellow proclaiming the Precious Blood. That was Potterism,
because it was an appeal to sentiment over the head, or under the head,
of reason. Neither the speaker nor any one else probably had the least
idea what he was talking about or what he meant.

'He had the kind of face which is always turned away from facts,' Gideon
said. 'Facts are too difficult, too complicated for him. Hard, jolly
facts, with clear sharp edges that you can't slur and talk away.
Potterism has no use for them. It appeals over their heads to prejudice
and sentiment.... It's the very opposite to the scientific temper. No
good scientist could conceivably be a Potterite, because he's concerned
with truth, and the kind of truth, too, that it's difficult to arrive at.
Potterism is all for short and easy cuts and showy results. Science has
to work its way step by step, and then hasn't much to show for it. It
isn't greedy. Potterism plays a game of grab all the time--snatches at
success in a hurry.... It's greedy,' repeated Gideon, thinking it out,
watching Jane's firm little sun-browned hand with its short square
fingers rooting in the sand for shells.
