In 1770, Baron D'Holbach published his masterpiece, "Systeme de la Nature", which for a long time passed as the posthumous work of M. de Mirabaud. That text-book of "Atheistical Philosophy" caused a great sensation, and two years later, 1772, the Baron published this excellent abridgment of it, freed from arbitrary ideas; and by its clearness of expression, facility, and precision of style, rendered it most suitable for the average student. This text is based on an undated English translation of "Le Bon Sens" published c. 1900. The name of the translator was not stated. (Summary from editor's preface)
