Against the Gods
The book “Against the Gods: The Remarkable Story of Risk” by Peter L. Bernstein explores the concept of risk and its importance in human history. The author argues that the ability to understand and manage risk is one of the defining features of modern society. The book is organized into several chapters, each focusing on a different period of history and examining the role of risk during that time.
The book begins with an introduction that sets the stage for the exploration of risk throughout history. The author argues that risk is an inherent part of human existence and that the ability to manage it is crucial for progress and development. The introduction also introduces the concept of risk management and its importance in various fields such as finance, insurance, and decision-making.
The first part of the book, titled “To 1200: Beginnings,” explores the early origins of risk and its role in ancient societies. Chapter 1 examines the connection between risk and chance, focusing on the role of dice games in ancient Greece. The author argues that the introduction of odds and probability in gambling marked a significant shift in human thinking about risk.
Chapter 2 dives deeper into the mathematical foundations of risk management, focusing on the Fibonacci sequence and its application in constructing an equiangular spiral. The author explains how this mathematical concept is related to risk and how it has influenced various fields, including art and architecture.
The second part of the book, titled “1200-1700: A Thousand Outstanding Facts,” explores the Renaissance period and its impact on the understanding and management of risk. Chapter 3 explores the role of gambling in the Renaissance, highlighting the ideas of famous gamblers and mathematicians such as Girolamo Cardano and Blaise Pascal.
Chapter 4 delves into the influence of French mathematicians on the development of probability theory. The author discusses the work of Pierre de Fermat and Blaise Pascal, particularly their contributions to the field of probability and their famous wager on the existence of God.
Chapter 5 focuses on the “remarkable notions” of Abraham de Moivre, a mathematician who made significant contributions to the understanding of probability. The author explores de Moivre’s work on the normal distribution and its application in various fields, including finance and biology.
The third part of the book, titled “1700-1900: Measurement Unlimited,” explores the period of Enlightenment and the rise of empirical thinking. Chapter 6 discusses the development of the concept of risk in relation to human nature and society. The author argues that understanding human behavior and psychology is crucial in managing risk effectively.
Chapter 7 explores the search for moral certainty and the role of ethics in decision-making. The author discusses the work of Jeremy Bentham and his concept of utilitarianism, which seeks to maximize happiness and minimize risk.
Chapter 8 examines the concept of irrationality and its impact on decision-making. The author discusses the work of Charles Mackay and his book “Extraordinary Popular Delusions and the Madness of Crowds,” which highlights the role of emotions and irrational behavior in influencing financial markets.
Chapter 9 focuses on the work of Francis Galton and his exploration of the concept of heredity and its impact on risk. The author discusses Galton’s study of the relationship between the height of parents and the height of their offspring.
Chapter 10 explores the concept of correlation and its role in risk management. The author discusses the work of Francis Ysidro Edgeworth and Karl Pearson, who made significant contributions to the understanding of correlation and its application in various fields.
Chapter 11 discusses the role of statistics and probability in economics and finance. The author explores the work of economists such as Irving Fisher and John Maynard Keynes, who applied statistical methods to the study of risk and uncertainty.
The fourth part of the book, titled “1900-1960: Clouds of Vagueness and the Demand for Precision,” explores the period of modernization and the rise of scientific thinking. Chapter 12 focuses on the measurement of ignorance and the concept of uncertainty. The author discusses the work of Frank Knight and John von Neumann, who made significant contributions to the understanding of decision-making under uncertainty.
Chapter 13 explores the radical shift in thinking about probability and uncertainty brought about by the work of Bruno de Finetti and Leonard Savage. The author discusses the concept of subjective probability and its application in decision-making.
Chapter 14 focuses on the work of Harry Markowitz and his development of portfolio theory. The author explains how Markowitz’s work revolutionized the field of finance by introducing the concept of diversification and its role in managing risk.
Chapter 15 examines the concept of efficient markets and the role of information in managing risk. The author discusses the work of Eugene Fama and his theory of efficient markets, which argues that all available information is already reflected in market prices.
The final part of the book, titled “Degrees of Belief: Exploring Uncertainty,” explores the concept of belief and its role in decision-making under uncertainty. Chapter 16 discusses the failure of invariance and the limitations of traditional measures of risk. The author explores the work of Daniel Ellsberg and his criticism of the concept of objective probability.
Chapter 17 explores the concept of risk aversion and its impact on decision-making. The author discusses the work of economists such as John Pratt and Amos Tversky, who introduced the idea of prospect theory and its application in understanding risk preferences.
Chapter 18 focuses on the concept of side bets and the role of betting in managing risk. The author discusses the work of economist Kenneth Arrow and his exploration of the concept of insurance as a form of risk management.
Chapter 19 concludes the book by discussing the role of uncertainty in human progress. The author argues that the ability to embrace uncertainty and take calculated risks is crucial for innovation and advancement.
The book concludes with a bibliography, name index, subject index, and end user license agreement. Throughout the book, the author uses various examples, illustrations, and charts to illustrate complex concepts and make them more accessible to the reader. The author also provides a list of acknowledgments, dedicating the book to Peter Brodsky and expressing gratitude to all those who provided assistance and support during the writing process.
