The Skeptical Chemist, or Chemico-Physical Doubts and Paradoxes Concerning the Principles of the Spagyrists, Commonly Called Hypostatic: How They Used to be Proposed and Defended by the Generality of Alchemists, is an outstanding work by Robert Boyle. The book explores the basics of chemistry and physics, disproves stereotypes about alchemy, and offers reasoned doubts about its principles. A part of another discussion is also added to this work, which complements the topic and expands the understanding of the scientific principles of the time. "The Skeptical Chemist" is an important contribution to the development of science and adheres to high standards of validity and criticality.
