About this book

What if your firmest beliefs about cause, self, and right and wrong rest on something other than reason?

In A Treatise of Human Nature, David Hume turns observation toward the mind itself. He wants to ground the study of human nature in experience, rather than guesswork or inherited theory. Through sections on the understanding, the passions, and morals, he asks how we form ideas, reach conclusions, and come to trust what we think we know.

The questions soon become personal. What makes you believe that one event causes another? What holds your sense of self together? Where do judgments of right and wrong begin? Hume examines habit, perception, feeling, and sympathy, offering answers that unsettle familiar assumptions. His inquiry invites you to watch your own mind at work, step by step.

In short

Why do you expect the sun to rise tomorrow? You have never seen tomorrow, and Hume thinks the usual answer is wrong.

Ein Traktat über die menschliche Natur by David Hume, the cover

From the 15-minute summary · Key idea 1

All ideas begin as feelings and sensations

Hume sorts everything in the mind into two kinds. Impressions are the lively ones, such as sensations and emotions as they first strike you. Ideas are their faint copies, which appear when you think or remember. You feel the gap between touching fire and thinking of it.

What is A Treatise of Human Nature about?

It is an attempt to build a science of the mind on observation. Hume examines how ideas arise, how we reason about cause and effect, how emotions work, and how we come to feel that actions are right or wrong.

What is the difference between impressions and ideas in Hume?

Impressions are the lively perceptions of sensation and feeling as they first strike you. Ideas are their fainter copies in thought and memory. Hume argues that every simple idea is derived from a matching impression.

What does Hume say about cause and effect?

He says we never observe a hidden force linking a cause to its effect. We see only that two things have been joined many times. The sense of necessity comes from the mind's habit of expecting the second after the first.
