This work is a minor classic of financial literature. Business historian Peter L. Bernstein wrote it during the early 1990s, when faith in the power of quantitative models and financial engineering was at its apex, and he tells a heroic story. Beginning with Greek mythology, Bernstein shows how cultural ideas about risk and probability evolved through Arab mathematics, the European Enlightenment and Chicago School economics. He writes in a spare, straightforward style, and manages to convey the essentials of financial theory and the essences of great economists without losing the reader in a maze of equations. Of course, the 2008 financial crisis cast probabilistic models and financial engineering as global market villains. In retrospect, that makes Bernstein's evident admiration for those models seem rather touchingly ingenuous. Nonetheless, getAbstract finds that this is still one of the best popular introductions to the development of financial science.

Before plunking any money into any investment, read this book first. It may seem more of a chronology of probability and statistics at first, but stick with it. More importantly, this book will help you understand risk so you go into investments with both eyes open. This book would be a 'must-read' even if it did not venture into applications to the stock market. It is well researched and written.

A great read... much more provocative and satisfying than some of the Longitude-style attempts at reasssessing big history. Bernstein looks at society and the growth of modern capitalism using the lode stone of risk, mixing math and history in an extraordinarily original way.

From Barnes & Noble
The Barnes & Noble ReviewWhat is it that distinguishes the thousands of years of history from what we think of as modern times? This is the question Peter L. Bernstein asks in the beginning of his new book, Against the Gods, and the answer put simply is...risk management.
Risk management? Well, that's not very poetic, is it? But as Bernstein points out, risk is essential to the development of our society; this is as true as the maxim 'nothing ventured, nothing gained' is old. But how did we discover the proper method for calculating insurance premiums in the first place? At what price should a crop future be set so as to be fair to both buyer and seller? It is questions like these that Bernstein, the author of a number of books on economics and finance, answers as he traces the emergence of risk management from calculating the probability of dice games to insuring investment portfolios.
Risk management by definition has to do with 'maximizing the areas where we have some control over the outcome while minimizing the areas where we have absolutely no control over the outcome and linkage between effect and cause is hidden from us.' But at the end of the day, a risk is still a risk no matter how carefully measured, so where does the time-honored 'gut feeling' come into play? This is the central question of Against the Gods, and the answers are enlightening.
We have Blaise Pascal and his probability triangle to thank for the birth of risk management. Pascal solidified the notion that there was a difference between playing games and thinking about playing games. His triangle of numbers is ageometric algebraic equation that can be employed to calculate, for instance, the odds that a team down one game to zero in the World Series has of coming back to win the pennant. (There are 22 combinations of wins and losses out of a possible 64 that the underdog will come back to win, by the way.) The problem with applying such calculations to real-life situations is that pure odds only work if each team has an equal chance of winning.
It wasn't until the Reformation that people began to that understand that they must take responsibility for their own decisions, and as Bernstein duly points out: 'Risk management only becomes possible when people are free agents.' So as awareness of self-determination spread, mathematicians put their minds to methods of determining risk while businessmen put their wallets towards using this information to limit risk.
It was in 1976, however, that one of the most highly developed forms of risk management heretofore imagined was spawned, from the mind of a Berkeley finance professor named Hayne Leland. For a premium, portfolio insurance guarded an investor against incurring huge losses in the stock market. Hayne had devised a scheme that severely limited the downside of the riskiest institution of all! For a time, everything went along gloriously for portfolio insurance, making millions for Leland, until the market crash of October 1987, when such huge losses could not be traded against the income of the premiums paid. At the end of the day, the best risk management failed in the face of the market's oldest precept: You cannot expect to make large profits without taking the risk of large losses. Related work was done by economists Robert C. Merton and Myron S. Scholes: For their mathematical theorems that accurately priced options (thereby drastically reducing the risk factor), they were recently awarded the Nobel Prize in Economics. Their theory is explained in depth in Against the Gods.
I felt a growing sense of anticipation as I read this book, expecting that the progress of risk management would lead me directly to the best investment strategies available. And though the book indeed follows this path, risk management as we know it today stops well short of achieving a foolproof method of playing the market. More to the point, it is human nature that does not allow these measurements to limit risk. "Against the Gods" reads like a good piece of historical fiction in which the events, facts, and dates come alive in the midst of the personalities who effected them. Pascal, for example, renounced mathematics twice in his life, both times turning to religion. With the claim of Renunciation, total and sweet, he gave up high living in favor of the monastery, leaving the unsolved intricacies of managing risks to future generations. And perhaps it is well he did, for it seems that we adhere more to the blind faith, rules of thumb, experience, instinct, and conventions that make up our gut than to the results of risk analysis.—Woodall Taft is a freelance writer who resides near Silicon Valley.

An extraordinarily entertaining and informative book.Publishers Weekly - Publisher's Weekly
Risk management, which assumes that future risks can be understood, measured and to some extent predicted, is the focus of this solid, thoroughgoing history. Probability theory, pioneered by 17th-century French mathematicians Blaise Pascal and Pierre de Fermat, has made possible the design of great bridges, electric power utilities and insurance policies. The statistical sampling methods invented by dour Swiss scientist Jacob Bernoulli undergird diverse activities such as the testing of new drugs, stock-picking and wine tasting. Bernstein (Capital Ideas) animates his narrative with a colorful cast of risk-analyzers, including gambling addict Girolamo Cardano, 16th-century Italian physician to the Pope; and John Maynard Keynes, whose concerns over economic uncertainty compelled him to recommend an active, interventionist role for government. Bernstein also traces the development of business forecasting, game theory, insurance and derivatives, and surveys recent advances in risk forecasting made possible through chaos theory and by the development of neural networks.Library Journal
For several centuries, mathematics has been the language of the exact sciences. Only in the 20th century has mathematics become predominant in other fields, particularly economics and finance. In this book, Bernstein (Capital Ideas: The Improbable Origins of Modern Wall Street), head of an economic consulting firm, traces the development of probability theory from its beginnings in analyzing games of chance, through its application to statistical theory and insurance, up to its present use in developing investment strategies to control risk. He includes excellent sections on portfolio analysis and on investments in derivatives. Bernstein clearly describes the people, their work, and the events that have revolutionized the thinking on Wall Street. -- Harold D. Shane, Baruch College, City University of New YorkLibrary Journal

Finance: What Is It, Why Is It, and Where Is It? by Peter L. Bernstein
Finance is a small word, but it covers a huge territory that includes markets, banking, corporate finance, the art of forecasting, accounting, taxation -- and more. In this universe, financial markets are the sun, a dazzling creation around which all the other activities rotate. I set the scene in this short essay, therefore, with some observations about markets before turning to the rest of the subject.
What is that frenzied activity in financial markets all about? Markets are places where buyers and sellers come together to do business; financial markets deal in money and risk. Financial markets are in the first instance a vehicle for financing governments and enterprises that need money. Beyond that, financial markets are a place where owners of outstanding assets can convert those assets into cash, or where owners of cash can find longer-term uses for their money. Financial markets thus give holders of assets with future cash flows the option of realizing the discounted value of those future cash flows in the present. In short, financial markets give investors the opportunity to change their minds, to reverse earlier decisions, at a cost and with a degree of immediacy that direct investment cannot provide. Think of the difference between buying 1,000 shares of IBM for a client and a house for your family.
Reversibility of decisions is the key element in risk. The reversibility provided by financial markets is their most important attribute. Financial markets are a kind of time machine that allows investors to compress the future into the present. Without financial markets, all assets would be buy-and-hold. Financial markets also provide tradable assets that directly hedge risk, by performing the remarkable function -- similar to insurance -- of reducing the holder's dependence on the markets to reverse decisions that might turn out unfavorably. Along the way, financial markets provide divisibility of outstanding issues, which means that investors can reduce risk even further through the invaluable device of diversification.
Through all these methods of reducing the risk of owning assets, financial markets lower the cost of capital and stimulate the spirit of enterprise. Recognizing these features of financial markets is essential to understanding the character of the risks and required returns of nonmarket sources of finance, such as banking, direct investment, and venture capital.
The impact of time on finance is not limited to markets. Time and finance are only opposite sides of the same coin. Finance means that those without cash can obtain cash today instead of waiting until tomorrow or the next day or the next. Thus, time is at the core of all aspects of finance, whether the transaction is in tradable or illiquid assets and whether it involves the sale of newly created financial assets or outstanding issues.
Finance is a service. We cannot touch, smell, or test-drive the next transaction we undertake. As a result, finance cannot operate without trust. Accounting, law, and regulation are indispensable features of a successful financial system. They come first. Finally, because finance is so involved with time, finance is about the future. This means that the study of finance must include techniques of forecasting combined with the valuation of future cash flows. But the future is unknown. So we also require the whole methodology of risk management for those occasions when forecasts turn out to be wrong.
The field is challenging, exciting in its development, and a place to make a fortune -- but also intensely competitive. It is also a fast-moving business: Like many other areas of our economy today, finance seems to be hit by innovation piled on innovation with extraordinary speed. You either keep in step or fall by the wayside. The work of academics and theoreticians in finance is now so closely joined to the efforts of practitioners that continuing education is essential for success.
Studying the literature cannot assure us of getting rich, but ignoring what the experts have to tell us has a high probability of dooming us to failure.
