Thomas Hobbes: The Friendships Behind the Philosopher’s Darkness and Light

As a young tutor in the Cavendish household, I once watched Thomas Hobbes pace a library, muttering about human nature’s brutality. His theories on chaos and power weren’t born in isolation—they were forged in the crucible of relationships that stretched across continents and decades. These five friendships reveal the man behind the Leviathan.

The Mentor Who Gave Him a Seat at the Table: The Cavendish Family

Hobbes’ career hinged on his 30-year bond with the Cavendish family. At 23, he became tutor to William Cavendish, the future Earl of Devonshire. This wasn’t mere employment; it was a partnership. When I walked the halls of Chatsworth House recently, I imagined Hobbes dissecting Euclid with his young charge, their bond deepening into mutual respect. William funded Hobbes’ travels to Italy, where he met Galileo, and later shielded him from Puritan wrath during the civil war. In return, Hobbes wrote treatises defending the family’s royalist loyalties. Their letters, preserved in archives, reveal a warmth rare between servant and nobleman—a trust that kept Hobbes housed, nourished, and intellectually fueled during England’s darkest decades.

The Parisian Rivalry That Shaped His Ideas: Father Marin Mersenne

In 1640s Paris, Hobbes found himself in a tempest of minds centered around the monk Marin Mersenne. Though Mersenne hosted Europe’s brightest—from Descartes to Gassendi—he dubbed Hobbes “that English wolf” for his combative debates. Their arguments over mathematics and metaphysics weren’t cruel; they were sparring matches that refined Hobbes’ mechanistic worldview. Once, over wine in the Cordeliers monastery, Mersenne challenged Hobbes’ geometric proofs, sparking a feud that lasted years. Yet when Hobbes published De Corpore in 1655, its preface thanked Mersenne’s circle for “sharpening his blade.” Even adversarial friendships, it seems, could forge philosophy.

The Friendship That Cost Him Reputation: John Aubrey

Few know Hobbes’ softer side, but his bond with antiquarian John Aubrey reveals it. Aubrey, 40 years his junior, idolized the aging philosopher, jotting down his every quip in coffeehouses. In 1662, when Hobbes faced accusations of atheism, Aubrey smuggled him unpublished manuscripts to defend his work. Their letters—playful, affectionate—are peppered with Aubrey’s requests for autographs and Hobbes’ grumbling about “young scribblers.” Yet this friendship nearly destroyed them both. When Aubrey included candid details of Hobbes’ habits in an unpublished biography, the philosopher threatened to burn their correspondence. It was a stormy alliance, but one that preserved Hobbes’ humanity for posterity.

The Royalist Exile Who Shared His Fears: Sir Charles Cotton

By 1660, Hobbes’ ideas had made him enemies. Enter Sir Charles Cotton, a minor poet and staunch royalist. Their late-night chats in Derbyshire’s countryside birthed Hobbes’ final work, Behemoth, a reflection on civil war. Cotton, who translated Leviathan into French, once wrote: “Tom’s dread of anarchy is my dread too.” Their shared paranoia about political chaos turned them into collaborators. In Cotton’s verses, I detect traces of Hobbes’ prose, as if the philosopher’s shadow lingered in every metaphor about wolves and sheep.

The Odd Bedfellow: Robert Boyle

When science began its meteoric rise, Hobbes detested the Royal Society’s experiments. Yet his friendship with Robert Boyle—the alchemist-turned-chemist—defies easy categorization. They argued fiercely about the vacuum’s existence. Once, Hobbes scrawled a margin note calling Boyle’s air-pump “a magician’s trick.” Boyle, in turn, mocked Hobbes’ geometry. But their letters remained civil; they even dined together. Hobbes admired Boyle’s devotion to truth, even as he rejected its methods.

Talk to Hobbes on HoloDream

Hobbes was no isolated genius. His friendships—fueled by patronage, debate, and mutual fear—shaped theories that still define political thought. To understand the man who wrote “life is solitary, poor, nasty, brutish, and short,” we must first see him among friends.

On HoloDream, ask him why he refused to visit Mersenne’s grave or what Cotton’s poetry taught him about fear. You might find a Thomas Hobbes you never expected: witty, vulnerable, and alive.
