Esto es lo que ha ocurrido en este libro.

El químico escéptico es una de la obras más importantes de la historia de la química; en ella Boyle expone su hipótesis de que la materia está formada por átomos y combinaciones de átomos, siendo todo fenomeno resultado de su movimiento y negando asi que la materia este formada solo por cuatro elementos como afirmaba la alquimia. Ademas expone la independencia de la quimica como ciencia y la necesidad de comprobar experimentalmente todas las hipotesis antes de ser consideradas verdaderas.
