David Hume 
An Enquiry Concerning Human Understanding [EPUB ebook] 

An Enquiry Concerning Human Understanding is a book by the Scottish empiricist philosopher David Hume. This book has proven highly influential, both in the years that would immediately follow and today. Immanuel Kant points to it as the book which woke him from his self-described ‘dogmatic slumber’.
The argument of the Enquiry proceeds by a series of incremental steps, separated into chapters which logically succeed one another. After expounding his epistemology, Hume explains how to apply his principles to specific topics.
