This is the true joy in life, the being used for a purpose recognized by yourself as a mighty one; the being thoroughly worn out before you are thrown on the scrap heap; the being a force of Nature instead of a feverish selfish little clod of ailments and grievances complaining that the world will not devote itself to making you happy.

Beware of the pursuit of the Superhuman: it leads to an indiscriminate contempt for the Human.

Steven Davidoff opens a recent piece at The New York Times DealBook blog with the following words:
Reputation is dead on Wall Street.
This is powerful language. What does he mean?
Well, for one thing he means that the reputations of individual investment banks are no longer coterminous with the reputations of their executives and employees. He ascribes this to the tremendous growth in scale and complexity of financial markets over the past three decades:
Today’s Wall Street is not the Wall Street of 1907 when J.P. Morgan single-handedly used his reputation and wallet to stem a running financial panic.
Until the 1980s,… Wall Street was made up of traditional partnerships. These were small groups of investment bankers who represented companies in offering and selling securities and occasionally acquisitions. These bankers put their individual reputations on the line, because there were so few of them. Morgan Stanley, for example, had only 31 partners in 1970 and fewer than 1,000 employees.
But this began to change in the 1980s. Trading markets became much more sophisticated, and trading and brokerage became the investment banks’ primary business. This is a technology game. The better the technology, the better the trading and brokerage operation. Individuals became less important.
The growth of more complex capital markets and a global economy also created much larger financial institutions. Morgan Stanley now has more than 62,000 employees. These banks could use their assets and position to compete in the market for finance and trading. Again, individuals were less important as size dominated. A client now trades or does business with a bank based on its positions or ability to make a market or loan. The executive at the bank executing the transaction is unimportant.
In one respect, this is true. Lazard is no longer Felix Rohatyn. Goldman Sachs is no longer Sidney Weinberg. The

Contagion in Markets
It’s often remarked that stockmarket manias and panics are contagious, as though there’s some virus spreading through the markets, infecting the participants and causing their irrational behaviour. Of course, this is usually meant as a metaphor rather than something to be taken literally – it’s a nice conceit that there’s a disease “out there” causing us to all do stupid things all together.
However, humans are social animals, we live in social networks and networks are prone to attack at their weakest points. Models of how real and virtual diseases spread – the study of epidemiology – can give us clues as to what’s really happening when everything goes screwy. And it turns out that the more connected we are the more danger we’re in.
Rod Steiger’s Network
Most people are aware of the Kevin Bacon game which measures actors by how close they’ve come to acting with the prolific star of Flashdance. Someone who’s acted in the same film with Kevin has a Bacon number of 1, someone who’s acted with someone who’s acted in the same film as him has a number of 2, and so on. By tracing out this network researchers have been able to piece together the network of social connectedness amongst Hollywood actors. In fact it turns out that Mr Bacon isn’t anywhere near the most connected actor, and the thesps should actually be linked by the Rod Steiger number.
What’s really interesting, however, is what happened when the researchers looked at how the actors were connected. It turned out that the average actor has an average number of connections but that a few, key, thespians held the network together. These critical “nodes” had far, far more connections than most of their fellow luvvies. If you think of this as a network, then if you could somehow remove the key players then suddenly the whole thing would fall apart.
Scale Free Networks
It turns out that this is a decent model for the way most social networks link and, in particular, for the way diseases spread. Epidemiologists have a real interest in understanding this because they’re interested in figuring out how to prevent the spread of diseases like
