Context

“We have said he has not the moral courage to wear his uniform; still less has he the moral courage to wear his coat-of-arms. The whole thing now is only a vague hotch-potch of nice and nasty gentlemen. The nice gentleman never refers to anyone else’s father, the nasty gentleman never refers to his own. That is the only difference, the rest is the public-school manner. But Eton and Harrow have to be aristocratic because they consist so largely of parvenues. The public school is not a sort of refuge for aristocrats, like an asylum, a place where they go in and never come out.” source
