How did John Locke’s ideas about property connect labor with ownership?

John Locke argued that the foundation of property begins with the individual's ownership of their own body. Because every person possesses their own person, they also possess the labor they perform with it.12

Locke posited that one acquires ownership of external objects by mixing their labor with them. When an individual applies effort to transform an unowned resource—such as cultivating a barren field into crops or building a house from raw wood—that labor creates a moral claim to the resulting product. By investing personal activity into the natural world, the individual extends their property right from their own body to the fruits of their work.12

This perspective served as a precursor to the labor theory of value, later developed by economists like David Ricardo and Karl Marx. While Locke’s theory remains influential, it has historically faced questions regarding the specific amount of labor required to establish a valid claim over natural resources like land.12
