This piece explores Carl von Clausewitz and his seminal work, "On War." It acknowledges the difficulty of reading Clausewitz due to his complex writing style but emphasizes the importance of his ideas in military strategy and beyond. The text provides a brief biography of Clausewitz, then simplifies some of his core concepts: war as politics by other means, the trinity of war (violence, chance, and reason), friction, and the importance of morale. It touches on the "3 Reciprocal Actions" from Book 1 that can escalate conflict and highlights the book's emphasis on war's complex interaction of political goals, human passions, chance, and rational calculation. The author suggests that Clausewitz's principles can be applied to various aspects of life, making his work relevant even for those outside the military field.
