Works & Achievements
Spinoza's absolute masterpiece, written according to the geometric method. In it he develops his metaphysics of the single substance, his theory of affects, and his conception of freedom as the comprehension of necessity.
Published anonymously, this founding work of modern biblical exegesis defends the freedom to philosophize and the separation between theology and philosophy. It was immediately banned.
An unfinished work in which Spinoza sets out his philosophical method and searches for the highest good capable of providing continuous and supreme joy.
The only work published under his own name during his lifetime, it expounds Cartesian philosophy in geometric form, accompanied by the Metaphysical Thoughts.
Spinoza's last work, left unfinished, in which he analyses the different forms of government (monarchy, aristocracy, democracy) while seeking the conditions for political stability.
The first draft of Spinoza's thought, rediscovered in the 19th century. Already present are the seeds of his philosophy of the single substance and of blessedness.
A collection of 88 letters exchanged with scholars, philosophers, and theologians from across Europe, invaluable for understanding the development of his thought and his intellectual debates.
Anecdotes
In 1656, at only 23 years old, Spinoza was struck by a herem (excommunication) from the Portuguese Jewish community of Amsterdam. The text of the ban was exceptionally violent, cursing him "by day and by night, lying down and rising up". He never sought to have this sentence lifted.
Spinoza earned his living by grinding optical lenses, a precision trade highly sought after at the time. This manual activity, which he practiced daily, allowed him to live modestly while remaining independent. Tragic irony: the glass dust inhaled over many years most likely contributed to the tuberculosis that carried him off at 44.
In 1673, the Elector Palatine Karl Ludwig offered him a chair in philosophy at the University of Heidelberg, with a promise of "the most extensive freedom to philosophize". Spinoza politely declined, fearing that academic obligations would limit his freedom of thought.
After the assassination of the De Witt brothers in 1672 by an Orangist mob in The Hague, Spinoza, deeply shaken, reportedly wanted to post a placard bearing the inscription "Ultimi barbarorum" (the last of the barbarians). His landlord allegedly locked him inside to spare him a similar fate.
Spinoza lived so frugally that his friends worried about him. At his death in February 1677, the inventory of his belongings revealed an extremely modest wardrobe and a library of around 160 works. His material estate barely covered the cost of his funeral.
Primary Sources

The end of the State is not to transform men from rational beings into beasts or automata, but on the contrary to bring it about that their minds and bodies perform their functions safely, and that they themselves make use of free reason.
I do not claim to have found the best philosophy, but I know that I understand the true one. If you ask me how I know this, I will answer: in the same way that you know that the three angles of a triangle are equal to two right angles.
By the judgment of the angels and the sentence of the saints, we excommunicate, expel, curse and damn Baruch de Spinoza, with the consent of the entire holy community, in the presence of the holy books.
After experience had taught me that all the things which regularly occur in ordinary life are vain and futile, I resolved to inquire whether there existed a true good capable of communicating itself.

Daily Life
Morning
Spinoza rose early and devoted his mornings to philosophical reflection and writing. He worked in his modest room, drafting his treatises or correspondence with European scholars. He would eat a frugal meal, sometimes nothing more than milk soup and oat porridge.
Afternoon
The afternoon was generally devoted to grinding optical lenses, his artisanal trade that ensured him modest financial independence. He sometimes received visits from friends and disciples with whom he discussed philosophy, science, and politics. He occasionally amused himself by watching spider fights.
Evening
In the evening, Spinoza smoked his pipe and conversed with his landlord or visitors. He continued his reading, particularly works on philosophy, mathematics, and optics. He went to bed relatively early, leading a regulated and sober life, frequenting neither taverns nor worldly entertainments.
Food
Spinoza led a life of great dietary frugality. He often made do with milk soup seasoned with butter, or porridge, and a light beer. His friends worried about this austerity, but he believed that simple food was sufficient to maintain bodily health and clarity of mind.
Clothing
Spinoza dressed simply, without any concern for fashion, but in a proper manner. He wore the typical clothes of a modest Dutch burgher of the 17th century: a white shirt, dark doublet, coat, and broad-brimmed hat. The post-mortem inventory mentions a very limited wardrobe.
Housing
Spinoza always lived as a lodger in other people's homes, never owning a house of his own. In The Hague, he rented a room in the house of the painter Hendrick van der Spyck on the Paviljoensgracht. His living space served simultaneously as bedroom, writing study, and lens-grinding workshop.

Visual Style
Style inspiré des maîtres hollandais du Siècle d'or, avec un clair-obscur chaleureux à la Vermeer et Rembrandt, centré sur l'intimité d'un intérieur modeste de philosophe-artisan.
AI Prompt
Dutch Golden Age interior painting style inspired by Vermeer and Rembrandt. Warm chiaroscuro lighting with a single source of natural light entering through a tall leaded glass window on the left, casting geometric patterns across a modest wood-paneled study. Rich amber and deep brown tones with occasional deep blue accents. A solitary philosopher at work, surrounded by books, manuscripts, and optical instruments. Dust motes floating in the beam of light. Muted earth tones with the luminous quality characteristic of 17th-century Dutch masters. Oil painting texture with visible brushstrokes, intimate domestic scale.
Sound Ambience
Atmosphère feutrée d'un intérieur hollandais du XVIIe siècle, entre le bruit régulier du polissage de lentilles et les sons lointains de la vie des canaux d'Amsterdam — cloches, bateaux et conversations.
AI Prompt
A quiet 17th-century Dutch interior: the steady rhythmic grinding of glass lenses on a polishing wheel, fine glass dust settling softly. Through leaded windows, the muffled sounds of Amsterdam canal life — distant church bells tolling the hours, the creak of merchant ships' rigging, water lapping against brick quays, horse hooves on cobblestones. Occasionally, the scratch of a quill pen on paper, the rustle of manuscript pages turning. A clock ticks steadily on the mantelpiece. Outside, seagulls cry and Dutch conversations drift up from the street below. The gentle whistle of wind through narrow alleyways between tall canal houses.
