Legacy of the angels

When medieval scholars sought to understand the nature of angels, they unwittingly laid the foundations of modern physics

What do the angelic forces of the Heavenly Host have to do with orgasms? The answer, according to the 12th-century philosopher and theologian Maimonides, was simple. Some invisible forces that caused movement could be explained by God working through angels. Quoting a famous rabbi who talked about ‘the angel put in charge of lust’, Maimonides commented that ‘he means to say: the force of orgasm … Thus this force too is called … an angel.’

Before the discovery of gravity, energy or magnetism, it was unclear why the cosmos behaved in the way it did, and angels were one way of accounting for the movement of physical entities. Maimonides argued that the planets, for example, are angelic intelligences because they move in their celestial orbits.

While most physicists would now baulk at angelic forces as an explanation of any natural phenomena, without the medieval belief in angels, physics today might look very different. Even when belief in angels later dissipated, modern physicists continued to posit incorporeal intelligences to help explain the inexplicable. Malevolent angelic forces (ie, demons) have appeared in compelling thought experiments across the history of physics. These well-known ‘demons of physics’ served as useful placeholders, helping physicists find scientific explanations for only vaguely imagined solutions. You can still find them in textbooks today.



But that’s not the most important legacy of medieval angelology. Angels also catalysed ferociously precise debates about the nature of place, bodies and motion, which would inspire something like a modern conceptual toolbox for physicists, honing concepts such as space and dimension. Angels, in short, underpin our understanding of the cosmos.
