A Silly Notion
"No silly notion of playing the hero--what have creatures like us to do with heroism who are not yet barely honest."
Unspoken Sermons, Second Series, LIFE
This saying is closely related to another MacDonald humorous truism:
"There is one kind of religion in which the more devoted a man is the fewer proselytes he makes: The worship of himself."
The Lonely Religion
ALEC FORBES, Vol. 2, chap. 1
MacDonald's humor is often at the expense of our hubris and silliness.
