 Both authors suggest that philosophical progress is the deepest condition of scientific progress.  Influenced by British empiricism, Turgot and Condorcet assert that all human knowledge is grounded in experience.  According to Turgot, the renaissance of science first required an empiricist turn, the abandoning of explanations appealing to faculties and essences.  The scientific experiment then found its place as the centerpiece of the scientific method and the vehicle of further progress (Turgot 1750, 45; 1751, 100–01).  Condorcet reiterates these points and also provides a wealth of examples of recent scientific discoveries (1795, 168–170).  Turgot and Condorcet agree that scientific progress is dependent on mathematical and technological progress, and vice versa (Turgot 1750, 45; Condorcet 1795, 231).
