Why did Michael Faraday believe that the forces of nature were unified?

Michael Faraday believed in the unity of the forces of nature because he viewed all such forces as manifestations of a single, universal force. Consequently, he reasoned that these forces ought to be convertible into one another.1

This conviction was deeply rooted in his approach to interpreting nature, which was significantly influenced by his membership in the Sandemanians, a small Christian sect. Furthermore, his scientific perspective was shaped by the atomic theory of Ruggero Giuseppe Boscovich, which posited that atoms were mathematical points surrounded by alternating fields of attractive and repulsive forces.2

Faraday’s experimental work consistently sought to demonstrate these interconnections, such as his discovery of the relationship between electricity and magnetism, and his later efforts to link these forces to light and gravity. His belief in this underlying unity ultimately led him to develop the concept of field theory, which provided the foundation for James Clerk Maxwell’s classical electromagnetic field theory.31
