In this chapter on metaphysics, the author begins with a discussion of the defects of metaphysics. The eternal questions. What am I? What can I know?--questions which it purports to answer--are left for all response as vague as the enveloping scholia. But the good that comes of evil is ever re-nascent, and out of the questions and answers have sprung the three foremost systems of modern anti-theistic thought. Of these, Pantheism takes the precedence, which is the due of age. Its nominal founder is Spinoza. After describing the life and philosophies of Spinoza, the author outlines the philosophies of what he calls the "the seven sages of Potsdam," including Voltaire, Maupertius, Frederick, Lamettrie, and D'Argens. He concludes with a description of the Baron d'Holbach and his guests, who startled the skeptic David Hume by professing their atheism. (PsycINFO Database Record (c) 2016 APA, all rights reserved)
