Gertrude Stein, 1935 — Modernist literature American writer Gertrude Stein was a self-styled genius who coined the term *Lost Generation* for a younger coterie of her fellow Modernist writers.

In The Magic Mountain, Thomas Mann explores the tension between rationalism and irrationalism by using a tuberculosis sanatorium as a microcosm for the intellectual and political crises of 20th-century Europe.12

The protagonist, Hans Castorp, arrives as a practical, rational young engineer but soon abandons his conventional life to succumb to the "seductions of disease, introspection, and death". Within the sanatorium, Castorp engages with various patients who represent the competing ideologies of the era. Through these interactions, the sanatorium serves as a spiritual reflection of the world below, where the "flat" rationalism of modern civilization clashes with the dangerous, creative irrationalism that Mann had previously explored in his earlier political writings.12

Ultimately, the novel functions as a bildungsroman in which Castorp must navigate these conflicting forces. His eventual decision to return to the world and serve his people represents a skeptical but humane rejection of the "perilous sympathy" for irrationality and death that had captivated the European soul leading up to World War I.12
