In 1820, a young, furious, independently wealthy philosopher named Arthur Schopenhauer arrived at the University of Berlin and made a calculated gesture of contempt: he scheduled his lectures at the very same hour as those of the reigning master, G. W. F. Hegel (Lesson 31). The students chose Hegel. Schopenhauer lectured to a nearly empty room, gave up, and spent the next decades nursing his loathing of "the System" and the optimism it preached. He was the first of the great rebels — and the nineteenth century would be the age of rebels, each hurling himself against the serene confidence that reason was marching through history toward freedom.
For the magnificent systems of Module 7 provoked an equal and opposite reaction. Where Hegel had seen Spirit realizing itself rationally in history, his successors saw something darker and more human underneath: a blind cosmic will (Schopenhauer), the solitary anguished individual the System could not absorb (Kierkegaard), the brute economic struggle that the talk of Spirit disguised (Marx), and the death of God and the will to power that all morality concealed (Nietzsche). These thinkers do not build cathedrals; they bring hammers. They are suspicious of reason itself — convinced that beneath our high ideas lie hidden forces (will, class interest, resentment, the unconscious) that the official philosophy was built to hide. Marx, Nietzsche, and Freud would later be called the "school of suspicion," and this module is where the suspicion begins.
Yet the century was not only demolition. The same decades that produced the European rebels produced, across the Atlantic, a more hopeful philosophy — the American transcendentalists and then the pragmatists, who asked not what ideas mean in the abstract but what difference they make in practice, and tied truth itself to consequences. And over all of it fell the longest shadow of the century: in 1859 Charles Darwin published On the Origin of Species, and the human being — lately crowned by Kant as a rational end in itself — was revealed as one more animal, shaped by blind natural selection. By 1900, the confident European mind of 1818 had been interrogated from every side: its God declared dead, its reason exposed as a mask, its species demoted to the apes, and its certainties handed over to whatever would work.

Threads to watch
What the self is is torn open from every direction: Schopenhauer's self as the objectification of a blind will, Kierkegaard's existing individual who must choose himself, Marx's self made by labor and class, Nietzsche's self as a shifting hierarchy of drives, and Darwin's self as an evolved animal — the unified rational subject of Kant is in pieces. Faith and reason reaches its modern crisis: Kierkegaard makes faith a leap against reason, Marx calls religion the opium of the people, Nietzsche pronounces God dead, and Darwin removes the last apparent need for a designer. The just society is refounded twice over, on opposite principles — Marx's classless society to be seized by revolution, and Mill's liberal society of maximal individual liberty under the harm principle. Who counts morally widens decisively, as Mill and Harriet Taylor argue for the full equality of women, the utilitarians extend moral concern toward all sentient beings, and Frederick Douglass and the first stirrings of Du Bois press the claims of the enslaved and their descendants. And running beneath them all, the new school of suspicion turns the deepest question back on philosophy itself: what if our reasons are not reasons at all, but masks?
Where this leads
The suspicion the rebels unleashed splits the twentieth century into two streams that will barely speak to each other. From the logical rigor prized by Frege and the British — and from a horror of the murky depths the nineteenth century had opened — grows the analytic tradition of Module 9, which retreats to language and logic and demands that every claim show its credentials. From the confrontation with existence, history, and power that Kierkegaard, Marx, and Nietzsche began grows the continental tradition of Module 10 — phenomenology, existentialism, critical theory, and the philosophies of suspicion in full flower. The single conversation that began in Miletus is about to divide in two.
State of the conversation
Returning after a break, or just starting here? Here is where things stand. The great systems of Module 7 have been stormed from every side. What the self is has fractured: the serene rational subject is now suspected of being driven by will (Schopenhauer), dread and choice (Kierkegaard), class (Marx), resentment (Nietzsche), and evolution (Darwin) — forces that reason does not control and may exist to conceal. Faith and reason have come apart violently, with God pronounced dead and religion explained away as projection, consolation, or class anaesthetic — even as Kierkegaard relocates faith beyond reason's reach entirely. The just society has split into the rival programs of revolution and liberty that will define the politics of the next century. And a new mood has entered philosophy: distrust of its own surfaces, the hunt for what hides beneath the reasons. The age of innocence about reason is over. Two great traditions are about to be born from its ending.
