a man must not hold himself aloof from the things which his friends and his community have at heart if he would be liked—especially as a statesman

Context

“They were always having grand tournaments there at Camelot; and very stirring and picturesque and ridiculous human bull-fights they were, too, but just a little wearisome to the practical mind. However, I was generally on hand—for two reasons: a man must not hold himself aloof from the things which his friends and his community have at heart if he would be liked—especially as a statesman; and both as business man and statesman I wanted to study the tournament and see if I couldn’t invent an improvement on it. That reminds me to remark, in passing, that the very first official thing I did, in my administration—and it was on the very first day of it, too—was to start a patent office;” source
