A Treatise of Human Nature

work by Hume

Quick Summary

A Treatise of Human Nature (1739–40) is a seminal work by Scottish philosopher David Hume that attempts to establish a science of human nature using the experimental method. Hume viewed philosophy as an inductive science focused on understanding human nature, concluding that humans are driven more by sentiment and practical feeling than by reason.1

The Treatise is divided into three books:
* Book I: Of the Understanding explores the origin of ideas, concepts of space and time, knowledge, probability, and the nature of causality. Hume famously questioned the necessary link between cause and effect, suggesting it arises from habit and constant conjunction rather than inherent necessity.12
* Book II: Of the Passions details psychological mechanisms explaining human emotions and the role of reason within them.1
* Book III: Of Morals defines moral goodness through feelings of approval or disapproval related to the consequences of human behavior.1

Although Hume later considered the Treatise a juvenile work, Book I significantly influenced subsequent philosophers, including Immanuel Kant. Hume's emphasis on experience and skepticism profoundly impacted epistemology and ethics.12
