We begin with the foundation of economics: human beings act purposefully to achieve their chosen ends. By examining human nature and the state of nature, we see how cooperation, exchange, and social order emerge incrementally. This sets the stage for all further inquiry into markets and society.

Building on human action, this pillar explains how economic knowledge is developed by examining the history of economic thought and the methods used to study human action. We show why economics differs from the natural sciences and cannot rely on prediction, measurement, or experimentation alone. Students learn how sound economic explanation is built and how to recognize methodological errors.

The division of labor allows individuals to specialize, raising productivity and making cooperation through exchange possible. As exchange expands beyond direct barter, money emerges historically as a medium of exchange. Money enables economic calculation, savings, and coordination across complex market systems.

The market order, or catallaxy, arises from voluntary interaction and dispersed knowledge. Entrepreneurship, capital, interest, prices, and profits are revealed as the mechanisms that coordinate action across society. Through these processes, markets harness knowledge and guide production toward human needs.

Trust and cooperation in markets are supported by institutions such as insurance, assurance, and reputation systems. These institutions evolve gradually to enable exchange among strangers. Their historical development illustrates the power of voluntary arrangements over state-imposed structures.

Conventional economics teaches that markets fail when confronted with externalities, public goods, monopolies, or common resources. From an Austrian perspective, these so-called failures reflect a misunderstanding of how markets adapt and resolve challenges. This pillar dismantles the myth of market failure by showing how voluntary solutions emerge.

We then explore how governance and property systems emerge without centralized authority. Law and defense are often assumed to be exclusive functions of the state. Yet history and theory show that jurisprudence, arbitration, and security can arise through contract and custom. This pillar explores how justice and protection arise through private institutions.

Finally, we turn to the ethical dimension of market life. Praxeonomy, as the extension of praxeology into ethics, grounds morality in human action rather than declared natural rights or utilitarian calculus. Philanthropy emerges as a voluntary expression of these ethics, completing the vision of a society rooted in freedom and cooperation.
