The cast of the voyage

Thirty great thinkers

Two and a half thousand years of philosophy, told as a route — each thinker a stop with a concise account, their own words, and where to read more.


Ancient Greece

600 BC – 200 AD

In a handful of Greek cities, people stopped explaining the world with myths and started asking for reasons. In two centuries they invented physics, ethics, logic and politics — and the questions they raised are still open today. Explore Ancient Greece

The Middle Ages

400 – 1400

For a thousand years, philosophy in Europe wrestled with a single problem: how to fit reason together with faith. Thinkers like Augustine and Aquinas built vast systems trying to prove that the two need not collide. Explore The Middle Ages

Early Modern

1400 – 1700

Printing, exploration and the new science shook every old certainty. Philosophers asked the question again from scratch — what can I actually know? — and split into rival camps of reason and experience. Explore Early Modern

Reason was turned on authority itself. From Kant to Marx, Darwin to Freud, thinkers remade morality, history, biology and the mind — and handed us the modern world, for better and worse. Explore Enlightenment & 1800s

Modern Times

1900 – now

With old certainties gone, the twentieth century asked what it means to be free, to find meaning, and to live honestly in a universe that began with a Big Bang. The voyage reaches our own time. Explore Modern Times

Eastern Voices

6th century BC onward

A parallel current runs through ancient China and India. Laozi, the Buddha, Confucius, Mencius and Zhuangzi asked how to live well, govern justly and find peace — arriving at answers that both echo and challenge the Greeks. Explore Eastern Voices
