# Common Stock

## Definition

The aggregate pool of goods and services created when individuals bring
their diverse specialised products together through exchange. Smith argues
that among humans, unlike animals, different talents are made useful to
one another because their products can be "brought, as it were, into a
common stock, where every man may purchase whatever part of the produce
of other men's talents he has occasion for." This common stock is the
emergent result of widespread exchange among specialised producers.

## Source Chapter

Book I, Chapter 2: "Of the Principle which gives Occasion to the Division
of Labour"

## Context

Appears in the chapter's concluding argument comparing humans and animals.
While a mastiff cannot benefit from a greyhound's speed due to lack of
exchange, humans can pool their different abilities through trade, making
all talents contribute to the general welfare.
