About this source

What it is

This manuscript is a handwritten copy of Spinoza's Ethics, made around 1675 by the copyist Pieter van Gent. It was passed to the Inquisition by Niels Stensen and is now held in the Vatican Apostolic Library. It is the only known surviving manuscript copy of the work and was rediscovered in 2010.

Why it matters

Because it was copied before Spinoza's friends edited the text for the printed Opera Posthuma, this manuscript lets scholars see an earlier version of the Ethics, closer to what Spinoza actually wrote. Its path into the Vatican archive, carried there by a former acquaintance who had turned to the Church, shows how dangerous Spinoza's ideas were seen to be even after his death.

Look closer

  • Why might a copy of a banned philosopher's work end up in the hands of the Inquisition?
  • What might differ between a handwritten copy and a printed edition prepared by friends?
  • What does the survival of only one manuscript copy tell you about how carefully Spinoza's works were controlled?
