Maxwell's Treatise on Electricity and Magnetism brought about what
Einstein called "the greatest change in the axiomatic basis of physics
since Newton." But Maxwell's aim was never to construct an axiomatic
theory. Instead, the Treatise presents an argument which, beginning with
the most characteristic electrical and magnetic phenomena, and
interpreting them as manifestations of continuous fields of electric and
magnetic energy, culminates in Maxwell's theory of light as a wave
motion within those fields.
The argument of the Treatise is not straightforwardly demonstrative but
is a dialectical one that can be challenging to discern among the many
topics presented. This book undertakes to extract and expound the
principal path of Maxwell's dialectical thinking.
