The book presents a philosophical argument against the notion of human freedom, drawing on the works of Bernier, Bayle, and Spinoza to assert that everything is governed by a physical order. It reconciles this materialism with the existence of a distant, Epicurean God. Additionally, the text critiques the validity of miracles and oracles, suggesting they are mere fables or deceptions. Influenced significantly by Fontenelle, the work culminates in a systematic treatise on the falsehood of miracles published in 1775, expanding on earlier discussions.
