If there is one person I do despise more than another, it is the man who does not think exactly the same on all topics as I do—foolish people, I say, then, who have never experienced much of either, will tell you that mental distress is far more agonizing than bodily.
 Jerome K. Jerome, Idle Thoughts of an Idle Fellow (1886). copy citation

Context

“We do not sigh over dead dicky-birds with the bailiff in the house, and when we do not know where on earth to get our next shilling from, we do not worry as to whether our mistress' smiles are cold, or hot, or lukewarm, or anything else about them. Foolish people—when I say "foolish people" in this contemptuous way I mean people who entertain different opinions to mine. If there is one person I do despise more than another, it is the man who does not think exactly the same on all topics as I do—foolish people, I say, then, who have never experienced much of either, will tell you that mental distress is far more agonizing than bodily. Romantic and touching theory! so comforting to the love-sick young sprig who looks down patronizingly at some poor devil with a white starved face and thinks to himself, "Ah, how happy you are compared with me!"—so soothing to fat old gentlemen who cackle about the superiority of poverty over riches.” source
