Context

“You can no more be certain in economic history that a man's desire for money was merely a desire for money than you can be certain in hagiology that a saint's desire for God was merely a desire for God. And this kind of vagueness in the primary phenomena of the study is an absolutely final blow to anything in the nature of a science. Men can construct a science with very few instruments, or with very plain instruments; but no one on earth could construct a science with unreliable instruments. A man might work out the whole of mathematics with a handful of pebbles, but not with a handful of clay which was always falling apart into new fragments, and falling together into new combinations.” source
