'That church,' he said, 'is the most unpleasant piece of Potterism I have seen for some time. Perpendicular, but restored fifty years ago, according to the taste of the period. Vile windows; painted deal pews; incredible braying of bad chants out of tune; a sermon from a pie-faced fellow about going to church. Why should they go to church? He didn't tell them; he just said if they didn't, some being he called God would be angry with them. What did he mean by God? I'm hanged if he'd ever thought it out. Some being, apparently, like a sublimated Potterite, who rejoices in bad singing, bad art, bad praying, and bad preaching, and sits aloft to deal out rewards to those who practise these and punishments to those who don't. The Potter God will save you if you please him; that means he'll save your body from danger and not let you starve. Potterism has no notion of a God who doesn't care a twopenny damn whether you starve or not, but does care whether you're following the truth as you see it. In fact, Potterism has no room for Christianity; it prefers the God of the Old Testament. Of course, with their abominable 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.
