# Section XII: Of Chastity and Modesty explained — A Treatise of Human Nature

> Chapter companion for A Treatise of Human Nature by David Hume.

## What happens

Hume examines the virtues of chastity and modesty, particularly as applied to women, arguing that these are not natural but arise from education, social conventions, and the interests of society. He explains that the need for male certainty of paternity leads to a social imposition of shame on female infidelity, which is reinforced by custom and extended beyond its original rationale.

## Themes in this chapter

### Artificial Virtues and Justice

Chastity and modesty are presented as artificial virtues, arising from social utility and convention rather than natural instinct.

### Custom and General Rules

Hume shows how general rules extend beyond their original basis, applying modesty to all women regardless of age, and how custom shapes moral sentiments.

## Character check-ins

### David Hume

Author and narrator, presenting a philosophical analysis of chastity and modesty.

## Key lines

> If any difficulty attend this system concerning the laws of nature and nations, it will be with regard to the universal approbation or blame, which follows their observance or transgression, and which some may not think sufficiently explained from the general interests of society.

If there is any problem with my theory about natural and social laws, it is that it may not fully explain why everyone approves or disapproves of these laws, beyond just the general good of society.

_Hume introduces the chapter by acknowledging a potential objection to his system._

> From this trivial and anatomical observation is derived that vast difference betwixt the education and duties of the two sexes.

This simple biological fact leads to the huge difference in how men and women are raised and what is expected of them.

_Hume traces the origin of gender-specific moral duties to a basic anatomical difference._

> But speculative reasonings, which cost so much pains to philosophers, are often formed by the world naturally, and without reflection.

What philosophers struggle to work out through careful thought, ordinary people often arrive at naturally and without thinking.

_Hume observes that social norms often develop organically without deliberate philosophical reasoning._
