René Descartes (1596—1650) is among the towering and important figures in Western philosophy and arithmetic. His apothegm “Cogito, ergo sum” marked the beginning of the mind-body challenge, whereas his construction of so-called Cartesian coordinates has made our highbrow conquest of actual area possible.

But Descartes had a mysterious and mystical part, to boot. in all likelihood a member of the occult brotherhood of the Rosicrucians, he stored a mystery computing device, now misplaced, such a lot of which used to be written in code. After Descartes’s demise, Gottfried Leibniz, inventor of calculus and one of many maximum mathematicians of all time, moved to Paris looking for this notebook–and ultimately came across it within the ownership of Claude Clerselier, a chum of Descartes’s. Liebniz referred to as on Clerselier and used to be allowed to repeat just a couple of pages–which, although written in code, he amazingly deciphered there immediate. Liebniz’s swiftly scribbled notes are all we've got this present day of Descartes’s notebook.

Why did Descartes hold a mystery pc, and what have been its contents? The solutions to those questions will lead the reader on an exhilarating, swashbuckling trip, and provide a desirable examine one of many nice figures of Western tradition.
