Rare and genuine posthumous first edition of the first six books of the Confessions, the remaining volumes not appearing until 1789.

It was regarding honesty that Méré and Pascal formed a long friendship. Pascal would...

A new, corrected and enlarged collected edition of the Œuvres philosophiques of Julien Offray de La Mettrie, published in 1764 and more comprehensive than the first collected edition issued in Berlin in 1751.
