Copy without the Meditationes 'The compilation of Descartes' texts into the 'Opera Philosophica' is an interesting phenomenon in the publishing history of the works of Descartes. From 1650 on Louis Elzevier started to sell the 'Meditationes', the 'Principia', 'Specimina' and the 'Passiones' as one set with the general title: 'Opera Philosophica'. Opera editions were published in 1650, 1656, 1663-4, 1670-72 and 1677-78. Whereas the Principia, Specimina and the Passiones were printed in the same year and are usually bound together, the Meditationes are the odd one out. They were published one or two years before the rest of the set (...). As a result the Meditationes were often bound separately, which make it hard nowadays to recognise whether a single volume of the Meditationes once was-or possible still is-part of a set of the Opera Philosophica.
