"When the little dog snarls, the big dog does not connect the snarl with himself, simply fancying that the little dog must be uncomfortable."
Here is an example of the simple wisdoms of Anthony Trollope. They are all things you kind of already know, but he has a way of putting them in writing so that they coalesce from vague assumptions into concrete truths in one's mind (at least in my mind).
So the above quote comes after a much longer passage where Trollope is discussing a resentful MP, Mr. Bonteen, who was promised the position of Chancellor of the Exchequer but got moved to a lesser non-cabinet position due to politics. He takes this with a lack of grace that everybody in the party notices, but the man who really matters. That man is Plantagenet Palliser, the previous Chancellor and now Duke of Omnium and something of a kingmaker in the Liberal party. Trollope writes so effecitvely about why Palliser is a big dog and then follows it up with the great quote above. I'll share it with you below if anybody has the time to read it and maybe you will get a sense of what I am trying to impart.
"Additional zest was given to all this by the very indiscreet conduct of Mr. Bonteen. He did accept the inferior office of President of the Board of Trade, an office inferior at least to that for which he had been designated, and agreed to fill it without a seat in the Cabinet. But having done so he could not bring himself to bear his disappointment quietly. He could not work and wait and make himself agreeable to those around him, holding his vexation within his own bosom. He was dark and sullen to his chief, and almost insolent to the Duke of Omnium. Our old friend Plantagenet Palliser was a man who hardly knew insolence when he met it. There was such an absence about him of all self-consciousness, he was so little given to think of his own personal demeanour and outward trappings,—that he never brought himself to question the manners of others to him. Contradiction he would take for simple argument. Strong difference of opinion even on the part of subordinates recommended itself to him. He could put up with apparent rudeness without seeing it, and always gave men credit for good intentions. And with it all he had an assurance in his own position,—a knowledge of the strength derived from his intellect, his industry, his rank, and his wealth,—which made him altogether fearless of others. When the little dog snarls, the big dog does not connect the snarl with himself, simply fancying that the little dog must be uncomfortable. Mr. Bonteen snarled a good deal, and the new Lord Privy Seal thought that the new President of the Board of Trade was not comfortable within himself. But at last the little dog took the big dog by the ear, and then the big dog put out his paw and knocked the little dog over. Mr. Bonteen was told that he had—forgotten himself; and there arose new rumours. It was soon reported that the Lord Privy Seal had refused to work out decimal coinage under the management, in the House of Commons, of the President of the Board of Trade."
