As for modern journalism, it is not my business to defend it. It justifies its own existence by the great Darwinian principle of the survival of the vulgarest.
None of this means, however, that a business or stock is an intelligent purchase simply because it is unpopular; a contrarian approach is just as foolish as a follow-the-crowd strategy. What's required is thinking rather than polling. Unfortunately, Bertrand Russell's observation about life in general applies with unusual force in the financial world: "Most men would rather die than think. Many do."
Physicians attend to the business of physicians, and workmen handle the tools of workmen.
[Lat., Quod medicorum est
Promittunt medici, tractant fabrilia fabri.]
At the risk of repetition let me say again that my plea is not for immunity to, but for the most unsparing exposure of, the politician who betrays his trust, of the big business man who makes or spends his fortune in illegitimate or corrupt ways. There should be a resolute effort to hunt every such man out of the position he has disgraced. Expose the crime, and hunt down the criminal; but remember that even in the case of crime, if it is attacked in sensational, lurid, and untruthful fashion, the attack may do more damage to the public mind than the crime itself.
That a man can take pleasure in marching in formation to the strains of a band is enough to make me despise him. He has only been given his big brain by mistake; a backbone was all he needed.
To invest successfully, you need not understand beta, efficient markets, modern portfolio theory, option pricing or emerging markets. You may, in fact, be better off knowing nothing of these. That, of course, is not the prevailing view at most business schools, whose finance curriculum tends to be dominated by such subjects. In our view, though, investment students need only two well-taught courses - How to Value a Business, and How to Think About Market Prices.
