The love of money as a possession-as distinguished from the love of money as a means to the enjoyments and realities of life-will be recognized for what it is, a somewhat disgusting morbidity, one of those semi-criminal, semi-pathological propensities which one hands over with a shudder to the specialists in mental disease

The difficulty lies, not in the new ideas, but in escaping from the old ones.

If human nature felt no temptation to take a chance there might not be much investment merely as a result of cold calculation.
