“I would define ‘avarice’ as a consequence of the human estate: a condition arising from turbulence and inequality. In none of the paradises, where conditions are no doubt optimum, does ‘avarice’ exert force. Here, we are men struggling toward perfection and ‘avarice’ is a station along the way.”

Context: Avarice, the spur of industry, is so obstinate a passion, and works its way through so many real dangers and difficulties, that it is not likely to be scared by an imaginary danger, which is so small, that it scarcely admits of calculation. Commerce, therefore, in my opinion, is apt to decay in absolute governments, not because it is there less secure, but because it is less honourable.

Context: One of the most significant results of the industrial struggle during the past fifty years has been the creation of a condition of a vast inequality of wealth and income.
