Arguments in Favour of Action at a Distance
Several arguments favouring instantaneous action at a distance are presented. The action at a distance laws of Newton, Coulomb, Amp?re and Weber are analysed. Historical evidence that Weber\'s electrodynamics led to the propagation of electromagnetic signals with finite velocity prior to the development of Maxwell\'s equations are emphasized. The implementation of Mach\'s principle with Weber\'s law applied to gravitation is discussed.
