歷史學家貝特妮·休斯（Bettany Hughes）追述三位偉大的思想家，他們的想法塑造了現代世界：卡爾馬克思，弗裏德裏希·威廉·尼采，和西格蒙德·弗洛伊德。出生於19世紀，他們生活在舊的確定性分崩離析的時代。政權被大眾起義推翻，而科學正在削弱宗教權威。他們的挑戰在於分析出在壹個快速變化的世界中什麽仍舊使我們人之為人。
Historian Bettany Hughes retraces the lives of three great thinkers whose ideas shaped the modern world: Karl Marx, Frederick Nietzsche and Sigmund Freud.
Born in the 19th century, they lived through a time when old certainties were breaking down. Regimes were overthrown by mass uprisings, science was undermining religious authority. Their challenge was to figure out what makes us human in a fast-evolving world.
