This book mainly discusses "gentleman education" and discusses how to consolidate the achievements of the British bourgeois revolution through education. John? Locke comprehensively analyzed the characteristics of "gentleman" and put forward that physical education, moral education and intellectual education are the core parts of education, so this book mainly talks about these three aspects.

For the first time in the history of western education, this book divides education into three parts: physical education, moral education and intellectual education, and systematically discusses each part. These thoughts inherited Montaigne's educational theory in the Renaissance, inspired the educational thought in the French Enlightenment in the18th century, and had a far-reaching impact on the development of modern western educational theory.

The book is divided into four parts: section 2 17. The first part talks about sports health care, the second part talks about moral education, which is the focus of the book, the third part talks about intellectual education, and the fourth part draws a conclusion. The theme of "Random Talk on Education" is "Gentleman Education". The author thinks that the purpose of education is to cultivate gentlemen. A gentleman must have five qualities: healthy body, virtue, wisdom, etiquette and knowledge.

In the first part, the author thinks that a healthy body is very important. As an "expert" who has studied medicine and natural science, the author puts forward many concrete opinions on children's sports, health and maintenance. The second part mainly talks about virtue, which is the most important content of this book. In all kinds of human behaviors, virtue comes first. Children must have a sound spiritual development on the basis of having a healthy body, cultivate children to restrain their desires with reason, and cultivate children to form good personality habits from an early age. The third part discusses wisdom and learning. The author thinks that virtue is more important than intellectual education, and learning is to open children's minds.
