Description

About this book

"Essays, or discourses, vol. 4 (of 4) : Selected from the works of Feyjoo, and…." by Feyjoo is a collection of philosophical essays written in the late 18th century. The volume gathers short, argumentative pieces on natural philosophy, epistemology, and morals that challenge inherited Aristotelian doctrine and promote cautious, experiment‑based reasoning. Expect lively “paradoxes” that overturn common opinions about fire, air, water, and qualities, alongside reflections on the limits of human knowledge and the pretensions of learned display. It will appeal to readers of Enlightenment thought, history of science, and skeptical philosophy. The opening of the volume presents a table of contents and then launches into “Physical Paradoxes,” where the author argues from experiments that solar heat concentrated by burning‑glasses surpasses elemental fire, that air is naturally cold absent the sun’s influence, and that water tends toward solidity, not fluidity.
