From our heartbeats to the stock market, climate change, political upheaval, and the Sun's orbit around the galaxy...
The world moves according to a set 'cycle'!

Our human heartbeats, the changing seasons, the cycle of boom and bust, the never-ending political upheaval, even the Sun's orbit around the galaxy... all movements in the world follow a certain cycle.
After decades of research, Dewey explored all aspects of the universe and established the laws of cycles.
"Cycles" begins with the question, "Are there cycles in nature, war, Wall Street, the universe, and humanity? If so, what are their relationships and how do they function?" This book analyzes recurring cycles in diverse fields, including history, botany, astronomy, and economics.


This book explores the correlations between biological, geological, and social cycles, and even the possibility of synchronization between different cycles, providing scientific evidence along with 66 extensive diagrams.
These cycles help us make better decisions.
Dewey said in his book:
"What if a driver, blindfolded and unable to see what's coming toward them while backing up, realized that the road they were traveling on had a certain pattern? What if there was a certain structure to the road, and if the driver could simply grasp this structure and predict where and how the road would bend? Wouldn't that be truly amazing? Cycling has exactly this structure."

The cycle recognizes this order of repetition and contains the method of avoiding crisis and seizing opportunity within it.
Compiled from decades of data and insights, this book will teach you how to read the hidden structures of the world beyond what is visible.


After decades of research following the Great Depression, the bible of cyclical theory is back!
The one and only book that penetrates the essence of the repetitive world!

《Cycle》was born in 1929 during the Great Depression, the greatest economic shock to humankind.
Herbert Hoover, then U.S. President, assigned economist Dewey the task of identifying the causes of the Great Depression.
After decades of research, Dewey made a surprising discovery.
Economic fluctuations, wars, grain prices, and even solar activity all repeat in regular cycles.


Born in the wake of the Great Depression, cycle theory revealed that not only economic fluctuations but also wars, grain prices, and even solar activity follow a certain rhythm.
It was the result of persistent thinking that sought to penetrate the essence of repetition and change experienced by human society.
Decades of data and historical insights were condensed into a single, colossal framework, the culmination of which was revealed to the world in 1971, just as the world was abandoning the gold standard and entering a new order.
Published at this time, "Cycle" went beyond simple economic analysis and became a compass for reading the world's trends, and was used by countless people as a tool for understanding order in repetition.


And today, with inflation, a debt crisis, and geopolitical instability all intertwined, we find ourselves at another turning point in the cycle.
“What have we learned and what have we forgotten in this recurring cycle?” Cycle poses this question and puts it before the reader once again.

Remember that understanding the past is not simply a study of history; it is the most powerful way to prepare for the future.
Then you will realize that this book is not simply a book of humanistic philosophy or past data.
The cycle contains timeless insights and offers wisdom that remains relevant today.
If you want to understand the essence of the world, don't miss "Cycle," which is full of data and objective facts.

There are waves in the market, there are trends in the times, and there is rhythm in the industry!
If you want to know about the uncertain future, read 'Cycle'!

As Mark Twain said, “History doesn’t repeat itself, but it does repeat itself.”
The cycle acts as a tool to penetrate that flow.
In times of widespread uncertainty, we must find direction in recurring patterns.
Ray Dalio says, “There are certain patterns in the flow of history, and we can use these to predict the future.”
Howard Marks also emphasizes that “the most important thing in investing is understanding cycles, not markets.”


《Cycle》 presents evidence, through numerous data and diagrams, that the world we live in is influenced by cycles.
Chapters 1 and 2 introduce the cycles around us, explain how we are affected by them, and what it means to know the cycles.


Chapter 4 shows the various mental and physical changes we experience through our body's blood pressure, blood flow, and brain wave cycles.
“Why are some days so happy, and some days so depressed?” “Is there a cycle to creativity?” It poses various questions like these and infers the answers (Chapter 4: Our bodies and minds move in cycles).
Chapter 6 shows how group psychology has driven political upheaval, from the French Revolution to the social movements following the Great Depression (Chapter 6: The Cycle Created by Crowds).

Chapters 7 and 8 prove various facts through past data from Cycles, the journal of the Cycling Research Foundation where Dewey worked.
First, Chapter 7 reveals that grain harvesting and manufacturing production repeat in a certain rhythm and determine the rise and fall of industry (Chapter 7: Can Production Be Predicted?).
Chapter 8 explains the principles of economic instability and financial crises by revealing that price movements, inflation and deflation, are not mere coincidences but cyclical patterns (Chapter 8: How Do Prices Move?).
Chapter 9 analyzes the fluctuations in stock prices that are created by the intertwining of stock prices, interest rates, liquidity, and public sentiment (Chapter 9: Cycles that Rule Wall Street).


Chapter 11 uses historical examples to illustrate the rise and fall of empires, the recurrence of international conflicts, and geopolitical instability (Chapter 11: Wars Repeat Endlessly).
And chapters 3, 10, and 12, which deal with the cycles of nature and the universe, cover the cycle of sunspots, climate change, and even the movement of galaxies, showing that all of these are closely connected to the society we live in (Chapter 3? Mysterious rhythms hidden in nature / Chapter 10? Why does it rain on January 23rd? / Chapter 12? There are cycles in the universe too).
In this way, Dewey meticulously reveals the 'order of repetition' that permeates politics, economy, society, and nature, and presents readers with a new frame for reading the future.

In times of uncertainty, understanding recurring structures becomes a survival strategy.
This book is not simply an economics book.
It is an intellectual tool that teaches us how to predict the future, seize opportunities, and avoid risks.
Do you want to understand the flow of the times? Do you want to understand the essence of change? Then read "Cycle."
It will provide a new framework of thinking for those who want to change their perspective on the world.
I highly recommend it to investors as well as anyone seeking a direction to move forward in the midst of change.
