The things I have symbolised by North and South, which are to me equal and opposite evils, each continually strengthened and made plausible by its critique of the other, enter our experience on many different levels. In agriculture we have to fear both the barren soil and the soil which is irresistibly fertile. … In art, we find on the one hand, purists and doctrinaires, who would rather … lose a hundred beauties than admit a single fault, and who cannot believe anything to be good if the unlearned spontaneously enjoy it: on the other hand, we find the uncritical and slovenly artists who will spoil the whole work rather than deny themselves any indulgence of sentiment or humour or sensationalism. Everyone can pick out among his own acquaintance the Northern and Southern types—the high noses, compressed lips, pale complexions, dryness and taciturnity of the one, the open mouths, the facile laughter and tears, the garrulity… . The Northerners are the men of rigid systems whether sceptical or dogmatic, Aristocrats, Stoics, Pharisees, Rigorists, signed and sealed members of highly organised ‘Parties’. The Southerners are by their very nature less definable; boneless souls whose doors stand open day and night to almost every visitant, but always with readiest welcome for those, whether Maenad or Mystagogue, who offer some sort of intoxication. The delicious tang of the forbidden and the unknown draws them on with fatal attraction; the smudging of all frontiers, the relaxation of all resistances, dream, opium, darkness, death, and the return to the womb. Every feeling is justified by the mere fact that it is felt: for a Northerner, every feeling on the same ground is suspect.

…In Theology also there is a North and South. The one cries ‘Drive out the bondmaid’s son,’ and the other ‘Quench not the smoking flax’. The one exaggerates the distinctness between Grace and Nature into a sheer opposition and …makes the way hard for those who are at the point of coming in. The other blurs the distinction altogether, flatters mere kindliness into thinking it is charity and vague optimisms or pantheisms into thinking that they are Faith, and makes the way out fatally easy and imperceptible for the budding apostate.
