Founders of the Wave: Descartes to Nietzsche

Socrates: the questioning method every later figure on this trail inherits, whether they answer him with a system (Descartes) or a critique (Nietzsche).

Rene Descartes founds Rationalism: certain truths about reality, reached by reason alone, prior to and independent of the senses.

Meditations on First Philosophy: the text itself, doubting everything down to a foundation that cannot be doubted.

Jean Bodin, a century before Hobbes, locates sovereignty in a single indivisible power, the idea the whole social-contract argument will spend three centuries contesting.

Six Books of the Commonwealth, Bodin's foundational statement of indivisible sovereignty.

Thomas Hobbes founds Social Contract Theory outright: without an absolute sovereign, life is a war of all against all.

Leviathan, 1651: the founding text of the whole tradition this trail now follows.

John Locke answers Hobbes with consent rather than surrender: legitimate government rests on the governed's own agreement, revocable if broken.

The Second Treatise of Government, Locke's case for consent, revolution, and limited power.

Jean-Jacques Rousseau pushes further still: legitimacy requires the general will itself, not merely consent once given.

The Social Contract, 1762: the tradition's last great restatement before it fractures into the critiques that follow.

Max Weber turns from what legitimates power to how it actually works, and to the spirit capitalism runs on.

Economy and Society, Weber's analytic account of authority, bureaucracy and the rationalization of modern life.

Karl Marx breaks with the whole contract tradition: legitimacy is not the question, class conflict over ownership is, and he attacks Bentham's utilitarian arithmetic by name along the way.

Das Kapital, the sustained critique of capitalism this whole wave's political cluster was building toward and against.

Samuel Taylor Coleridge carries German idealism into English letters and, through Emerson, into New England Transcendentalism.

Aids to Reflection, the specific book through which that transmission happened.

Thomas Carlyle, the second of Emerson's recorded influences, translating and popularizing German thought for an English readership.

Sartor Resartus, Carlyle's idiosyncratic philosophical satire of Victorian materialism.

Emanuel Swedenborg, the third recorded influence on Emerson, by way of a mystic's direct claim to visionary knowledge of the spiritual world.

Heaven and Hell, Swedenborg's account of the afterlife drawn from what he held were direct spiritual visions.

The Bhagavad Gita, translated into English in Emerson's lifetime and read by the Transcendentalists as a kindred scripture of intuited, unmediated truth.

Friedrich Nietzsche closes the trail by declaring the old certainties, moral and religious alike, dead, and asking what a person builds once they are gone.

Thus Spoke Zarathustra, the philosophical novel carrying that declaration into the Ubermensch, the will to power, and the eternal recurrence.
