This collection of text from Principles of Economics by Saifedean Ammous appears grounded in the Austrian school of economics. The author intends to provide a clear and readable explanation of core Austrian economic ideas, contrasting them with mainstream economic thought and emphasizing the importance of individual human action and subjective value. Key concepts explored include time preference, capital, technology, energy as power, the emergence of the market order through trade and the development of money (specifically highlighting the significance of hard money like gold and contrasting it with fiat currencies), and the role of property rights. The text further critiques government intervention, advocating for a society based on the non-aggression principle and viewing civilization as a product of peaceful cooperation, capital accumulation, and a long-term orientation while also criticizing fiat money's detrimental effects on economic calculation and societal progress.
