"A Treatise on Political Economy"by Antonie Louis Claude Destutt de Tracy (1754-1836) is a foundational text of nineteenth-century, free-market economic thought and remains one of the classics of nineteenth-century French economic liberalism. Destutt de Tracy was one of the founders of the classical liberal republican group known as the Ideologues, which included Benjamin Constant, Jean-Baptiste Say, Marquis de Condorcet, and Madame de Stael.In this volume, Destutt de Tracy provides one of the clearest statements of the economic principles of the Ideologues. Breaking with the physiocratic orthodoxy of the eighteenth century, Destutt de Tracy denies that land is the source of all productive labor and focuses his attention upon manufacturing and manufacturers as the producers of utility and, therefore, of value and of wealth. Placing the entrepreneur at the center of his view of economic activty, he argues against luxurious consumption of the idle rich and recommends a market economy with low taxation and minimum state intervention.Destutt de Tracy sent the text of "A Treatise on Political Economy "to Thomas Jefferson in hopes of securing its translation in the United States. It was met with enthusiastic approval. Jefferson wrote to the publisher, "The merit of this work will, I hope, place it in the hands of every reader in our country."

. Renewal of Life by Transmission. The most notable distinction between living and inanimate things is that the former maintain themselves by renewal. A stone when struck resists. If its resistance is greater than the force of the blow struck, it remains outwardly unchanged. Otherwise, it is shattered into smaller bits. Never does the stone attempt to react in such a way that it may maintain itself against the blow, much less so as to render the blow a contributing factor to its own continued action. While the living thing may easily be crushed by superior force, it none the less tries to turn the energies which act upon it into means of its own further existence. If it cannot do so, it does not just split into smaller pieces (at least in the higher forms of life), but loses its identity as a living thing. As long as it endures, it struggles to use surrounding energies in its own behalf. It uses light, air, moisture, and the material of soil. To say that it uses them is to say that it turns them into means of its own conservation. As long as it is growing, the energy it expends in thus turning the environment to account is more than compensated for by the return it gets: it grows. Understanding the word "control" in this sense, it may be said that a living being is one that subjugates and controls for its own continued activity the energies that would otherwise use it up. Life is a self-renewing process through action upon the environment.
