De, Marquis Sade 
Philosophy in the Bedroom [EPUB ebook] 

‘Philosophy in the Bedroom’ (La Philosophie dans le boudoir) is a provocative and controversial work by the French philosopher and writer Marquis de Sade, first published in 1795. This book is a dialogue-driven narrative that unfolds as a series of philosophical conversations and explicit sexual encounters, taking place within the confines of a bedroom.
The central characters include a young woman named Eugénie, her tutor Dolmancé, and Madame de Saint-Ange. The work is essentially an instruction manual on libertinage, advocating for the liberation of sexual desires and the rejection of traditional moral and religious norms. De Sade uses the setting and the explicit nature of the discussions to delve into themes of freedom, pleasure, and the nature of society’s rules and restrictions.
‘Philosophy in the Bedroom’ is emblematic of de Sade’s radical thought, blending philosophical discourse with erotic content. It is often seen as an important work in the study of libertine literature and philosophy, reflecting de Sade’s notorious reputation as a writer who challenged the boundaries of morality and decency in his era.
