Aepinus was the first to show that a theory of [[action at a distance]] for electricity provides simple explanation for experimental findings now known as [[electrostatic induction]], laying the foundations for [[electrostatics]]<ref name="Whittaker">{{Cite book |last=Whittaker |first=Edmund T. |title=A history of the theories of aether & electricity. 1: The classical theories |date=1989 |publisher=Dover Publ |isbn=978-0-486-26126-3 |edition=Repr |location=New York}}</ref>{{rp|52}} His theory resembled Newton's approach to gravity in that it relied on unexplained [[action at a distance]];<ref name=Home>Home, Roderick Weir. "Aepinus's Essay on the Theory of Electricity and Magnetism". United States, Princeton University Press, 2015.</ref> also like Newton Aepinus believed that the transmission of force required contact.<ref name=Sanford>{{Cite journal |last=Sanford |first=Fernando |date=1921 |title=Some Early Theories Regarding Electrical Forces--The Electric Emanation Theory |url=https://www.jstor.org/stable/6312 |journal=The Scientific Monthly |volume=12 |issue=6 |pages=544–550 |bibcode=1921SciMo..12..544S |issn=0096-3771}}</ref> These seeming contradictions reflect the modern scientific concept of approximate models of physical phenomena.
 
[[Henry Cavendish]] devised theories of electricity which were essentially the same, yet had been framed without any communication between these two philosophers. Aepinus  published his theory about ten years before that of Cavendish.  These are theories which eventually put to rest the idea of two fluids.
