"On Human Cognition" (i. E. "On Human Understanding") is an important work in the history of Western philosophy, especially in the epistemological tradition of modern philosophy. It is the pioneering work of the British empiricist epistemological tradition.
Since its first publication in 1689, Locke has repeatedly revised the book. Therefore, "On Human Cognition" was published in seven English versions in the early stage. There are many differences in terms between different versions. Niedich then compared and examined the seven editions of the book, and compiled a comprehensive revision of "On Human Cognition" so far with reference to the French and Latin translations. The Chinese translation was introduced for the first time. It shows us from a comprehensive perspective Locke's subtle changes in thought and differences in expression during the writing and subsequent revision of this book. Readers can compare the contents of different versions of "On the Knowledge of Mankind" during reading to gain a more detailed understanding of Locke's philosophical thoughts. For professional research on Locke's philosophical thoughts, this book has great reference value.
