This strain within the traditional British character (it is, historically, intertwined with Christianity) is important to understand if one wishes a full understanding of the Edwardians' (in general) and Marie Corelli's (in particular) reaction to the Deacadent movement. One small example is Gilbert & Sullivan's satiric operetta on aestheticism, entitled Patience. You'll be familiar with its immortal lines:
If you're anxious for to shine in the high aesthetic line / as
a man of culture rare ... And ev'ryone will say / As you walk your flow'ry way, / "If he's content with a vegetable love which would certainly not suit me, / Why, what a most particularly pure young man / this pure young man must be!"
