"It must be remembered that all trade is and must be in a sense selfish; trade not being infinite, nay, the trade of a particular place or district being possibly very limited, what one man gains another loses. In the hand to hand war of commerce, as in the conflicts of public life, whether at the bar, in Parliament, in medicine, in engineering (I give examples only), men fight on without much thought of others, except a desire to excel or to defeat them. Very lofty minds, like Sir Philip Sidney with his cup of water, will not stoop to take an advantage, if they think another wants it more. Our age, in spite of high authority to the contrary, is not without its Sir Philip Sidneys; but these are counsels of perfection which it would be silly indeed to make the measure of the rough business of the world as pursued by ordinary men of business. The line is in words difficult to draw. . . ."
