--- ENTITY: barter and exchange ---

# Barter and Exchange

## Definition

The voluntary trade of goods or services between parties without the use of money, where each participant gives up something they possess in return for something they desire, forming the fundamental basis of economic interaction and the division of labour.

## Source Chapter

Book I, Chapter 2

## Context

The chapter's central thesis, arguing that this propensity is the original principle that gives occasion to the division of labour. Smith demonstrates how the certainty of being able to exchange surplus produce encourages individuals to specialise in particular occupations.

## Economic Domain

Exchange

---
--- ENTITY: benevolence ---

# Benevolence

## Definition

The natural human disposition toward kindness and goodwill toward others, which Smith argues is insufficient as a basis for economic organisation since individuals cannot rely on others' benevolence alone to meet their needs in a complex society.

## Source Chapter

Book I, Chapter 2

## Context

Smith contrasts benevolence with self-interest as motivations for economic exchange, arguing that we do not expect our dinner from the butcher's benevolence but from his regard to his own interest, establishing self-love as the more reliable foundation for economic cooperation.

## Economic Domain

General Theory

---
--- ENTITY: contract ---

# Contract

## Definition

A formal agreement between parties that establishes mutual obligations and rights, which Smith notes is uniquely human as animals do not engage in contractual arrangements, marking a fundamental distinction between human and animal economic behaviour.

## Source Chapter

Book I, Chapter 2

## Context

Smith uses the absence of contracts in animal behaviour to illustrate that the propensity to truck, barter, and exchange is uniquely human, distinguishing human economic organisation from animal interactions.

Exchange

---
--- ENTITY: division of labour ---

# Division of Labour

## Definition

The separation of a work process into distinct tasks performed by specialised workers, increasing productivity through greater dexterity, saved time, and the invention of labour-saving machinery, originally arising from the propensity to truck, barter, and exchange.

## Source Chapter

Book I, Chapter 2

## Context

The chapter's central concept, described as the necessary consequence of human propensity to exchange, which allows individuals to specialise in particular occupations and thereby increase overall productivity and wealth.

## Economic Domain

Production

---
--- ENTITY: exchange ---

# Exchange

## Definition

The act of giving up something possessed in return for something desired, forming the mechanism through which surplus production is converted into useful goods and services, and enabling the division of labour by providing assurance that specialised output can be traded for needed goods.

## Source Chapter

Book I, Chapter 2

## Context

Smith identifies exchange as the fundamental economic mechanism that transforms individual self-interest into social benefit, arguing that it is this disposition which originally gives occasion to the division of labour.

## Economic Domain

Exchange

---
--- ENTITY: favour ---

# Favour

## Definition

The granting of benefits or assistance based on goodwill or personal relationship rather than contractual obligation or exchange, which Smith contrasts with market transactions as an insufficient basis for economic organisation in complex societies.

## Source Chapter

Book I, Chapter 2

## Context

Smith discusses how animals obtain what they want from humans or other animals by gaining favour, and how humans sometimes use similar arts of servility, but argues that in civilised society, complex economic needs cannot be met through favour alone.

## Economic Domain

Exchange

---
--- ENTITY: human nature ---

# Human Nature

## Definition

The inherent characteristics and propensities of human beings, particularly the universal disposition to truck, barter, and exchange, which Smith identifies as the fundamental principle underlying economic organisation and the division of labour.

## Source Chapter

Book I, Chapter 2

## Context

Smith argues that the propensity to exchange is common to all men and found in no other race of animals, suggesting it may be either an original principle of human nature or a necessary consequence of reason and speech.

## Economic Domain

General Theory

---
--- ENTITY: interest ---

# Interest

## Definition

The personal concern or advantage that individuals pursue in economic transactions, which Smith argues is the more reliable basis for obtaining cooperation than benevolence, as people are more likely to provide what others need when it serves their own advantage.

## Source Chapter

Book I, Chapter 2

## Context

Smith establishes that individuals are more likely to prevail in obtaining assistance when they can interest others' self-love in their favour, showing that economic transactions are driven by mutual advantage rather than altruism.

## Economic Domain

Exchange

---
--- ENTITY: mutual good offices ---

# Mutual Good Offices

## Definition

The reciprocal benefits and services that individuals provide to one another through economic exchange, which Smith argues constitute the greater part of what people need from one another in civilised society.

## Source Chapter

Book I, Chapter 2

## Context

Smith describes how mutual good offices are obtained through treaty, barter, and purchase, establishing exchange as the primary mechanism for meeting human needs in complex societies.

## Economic Domain

Exchange

---
--- ENTITY: necessity ---

# Necessity

## Definition

The fundamental requirements for human survival and comfort that individuals seek to obtain through economic exchange, which Smith argues cannot be reliably provided through benevolence alone but require the mechanism of self-interested exchange.

## Source Chapter

Book I, Chapter 2

## Context

Smith argues that man has almost constant occasion for the help of his brethren, and it is in vain to expect it from benevolence only, establishing necessity as the driving force behind economic exchange.

## Economic Domain

Consumption

---
--- ENTITY: self-love ---

# Self-Love

## Definition

The natural human concern for one's own advantage and well-being, which Smith identifies as the more reliable foundation for economic cooperation than benevolence, since individuals are more responsive to their own interests than to others' needs.

## Source Chapter

Book I, Chapter 2

## Context

Smith argues that we address ourselves not to the humanity but to the self-love of economic actors, establishing self-interest as the fundamental principle that makes economic exchange possible and reliable.

## Economic Domain

General Theory

---
--- ENTITY: subsistence ---

# Subsistence

## Definition

The basic necessities of life required for survival, which Smith argues are ultimately provided through the charity of well-disposed people for beggars, but for most people are obtained through treaty, barter, and purchase.

## Source Chapter

Book I, Chapter 2

## Context

Smith uses the example of beggars to illustrate that even those who depend on charity ultimately rely on exchange mechanisms for most of their needs, demonstrating the universal necessity of economic exchange.

## Economic Domain

Consumption

---
--- ENTITY: treaty ---

# Treaty

## Definition

Formal agreements or arrangements for exchange between parties, which Smith identifies as one of the three primary mechanisms (along with barter and purchase) through which individuals obtain mutual good offices in civilised society.

## Source Chapter

Book I, Chapter 2

## Context

Smith lists treaty, barter, and purchase as the means by which the greater part of mutual good offices are obtained, establishing the formal mechanisms of economic exchange.

## Economic Domain

Exchange

---
--- ENTITY: truck ---

# Truck

## Definition

The act of exchanging or bartering goods, particularly in the sense of trading commodities, which Smith identifies as one of the three forms of the fundamental human propensity that gives occasion to the division of labour.

## Source Chapter

Book I, Chapter 2

## Context

Smith lists truck, barter, and exchange as the three manifestations of the human propensity that forms the basis of economic organisation and specialisation.

## Economic Domain

Exchange

---
--- ENTITY: variety of talents ---

# Variety of Talents

## Definition

The natural differences in abilities and skills among individuals, which Smith argues are primarily the effect rather than the cause of the division of labour, as specialisation itself creates and amplifies differences in human capabilities.

## Source Chapter

Book I, Chapter 2

## Context

Smith argues that the remarkable difference of talents among men of different professions is not upon many occasions so much the cause as the effect of the division of labour, challenging the common assumption about the origin of human differences.

## Economic Domain

Production

---
--- ENTITY: venison ---

# Venison

## Definition

The meat of deer, used by Smith as an example of a commodity that hunters might exchange for bows and arrows, illustrating how the certainty of exchange encourages specialisation in particular occupations.

## Source Chapter

Book I, Chapter 2

## Context

Smith uses venison as an example in his discussion of how hunters and shepherds might exchange specialised products, demonstrating how the division of labour emerges from the propensity to exchange.
