Interview in Forbes magazine (1 November 1974)
Context: Draw a circle around the businesses you understand and then eliminate those that fail to qualify on the basis of value, good management and limited exposure to hard times. … Buy into a company because you want to own it, not because you want the stock to go up. … People have been successful investors because they've stuck with successful companies. Sooner or later the market mirrors the business.

1920s, The Press Under a Free Government (1925)
Context: There does not seem to be cause for alarm in the dual relationship of the press to the public, whereby it is on one side a purveyor of information and opinion and on the other side a purely business enterprise. Rather, it is probable that a press which maintains an intimate touch with the business currents of the nation, is likely to be more reliable than it would be if it were a stranger to these influences. After all, the chief business of the American people is business. They are profoundly concerned with producing, buying, selling, investing and prospering in the world. I am strongly of opinion that the great majority of people will always find these are moving impulses of our life. The opposite view was oracularly and poetically set forth in those lines of Goldsmith which everybody repeats, but few really believe: 'Ill fares the land, to hastening ills a prey, Where wealth accumulates, and men decay.'.
