pride oneself on

It is foolish to be interested in all that happens in the world; to pride oneself on one's knowledge of the market, of the King of England's plans, the news from Rome, conditions in Denmark.

Still, you never can tell; it don' do to pride oneself on anything.

I knew nothing of their careful gradations of snobbism—the people to know socially, the people to know in a business way, the people to know in ways religious and philanthropic, the people to know for the fun to be got out of them, the people to pride oneself on not knowing at all; the nervousness, the hysteria about preserving these disgusting gradations.

It is no longer proper—as in Homeric days—to pride oneself on one's cleverness in perjury and common falsehood.
