# How does A Treatise of Human Nature develop the theme of Morality as Sentiment?

> A Treatise of Human Nature by David Hume

## Answer

A Treatise of Human Nature by David Hume develops Morality as Sentiment across the chapters the companion marks for this theme.

Virtue and vice are distinguished not by reason but by the pleasure or pain they produce in the observer, making moral judgments a matter of feeling.

Hume suggests that philosophy, if just, presents only mild and moderate sentiments, contrasting this with the dangerous errors of religion, which can disturb the conduct of life.

Hume argues that vice and virtue are distinguished by the pleasure or pain they produce, aligning with the view that moral distinctions are based on sentiment.

Virtue and vice are cited as causes of love and hatred, indicating that moral judgments are tied to emotional responses.
