John "Walking" Stewart

John "Walking" Stewart (19 February 1747 – 20 February 1822) was an English traveller and philosopher.

Known as 'Walking' Stewart to his contemporaries for having travelled on foot from Madras, India (where he had worked as a clerk for the East India Company) back to Europe between 1765 and the mid-1790s. Stewart is thought to have walked alone across Persia, Abyssinia, Arabia and Africa before wandering into every European country as far east as Russia.

During his journeys, he developed a unique brand of materialist philosophy which combines elements of Spinozistic pantheism with yogic notions of a single indissoluble consciousness. Stewart began to promote his ideas publicly in 1790 with the publication in two volumes of his works Travels over the most interesting parts of the Globe and The Apocalypse of Nature (London, 1790).

Over the next three decades Stewart wrote prolifically, publishing nearly thirty philosophical works, including The Opus Maximum (London, 1803) and the long verse-poem The Revelation of Nature (New York, 1795).

In 1796, George Washington's portrait-painter, James Sharples, executed a pastel likeness of Stewart for a series of portraits which included such sitters as William Godwin, Joseph Priestley, and Humphry Davy, suggesting the intellectual esteem in which Stewart was once held.

After retiring from travelling, Stewart eventually settled in London where he held philosophical soirées and earned a reputation as one of the city's celebrated eccentrics. He was often seen in public wearing a threadbare Armenian military uniform.

On 20 February 1822, the morning after his seventy-fifth birthday, 'Walking' Stewart's body was found in a rented room in Northumberland Place, near present-day Trafalgar Square, London. An empty bottle of laudanum lay beside him.
