Alert readers of this blog may have realised that I am reading Henri Bortoft’s book Taking Appearance Seriously: The Dynamic Way of Seeing in Goethe and European Thought. Bortoft throws interesting insight into the role of Isaac Newton in creating the modern scientific world, confirming Edi Bilimoria’s article mentioned in an earlier post.
Isaac Newton basically invented modern mathematical physics in his masterwork, Principia Mathematica (1687). To the theory of atomism and mechanical philosophy he added the notion of forces which act between bodies that are not in contact.
Bortoft suggests that from the eighteenth century onwards, gravity began to be thought of as a ‘property of matter’, as if it were an attractive force inherent to matter. This is not what Newton thought. He did not believe in attraction as a real, physical, force.
For example, in a letter Newton said:
Pray do not ascribe that notion to me, for the cause of gravity is what I do not pretend to know and therefore would take more time to consider of it… Gravity must be caused by an agent acting constantly according to certain laws, but whether this agent be material or immaterial I have left to the consideration of my readers.
So Newton’s major discovery was to the effect that we could create mathematical models of the real world, what we now call ‘physics’. Subsequent founders of modern science were dedicated to the mathematical approach to nature, but ultimately the ascendancy of the mathematical was accompanied by the downgrading of the sensory and increasingly seeing the world as a mathematical abstraction. To many scientists the world became de-spiritualised and dead.
This was not Newton’s intention, although his name is often invoked as the originator of such a viewpoint.
One thought on “What Newton really thought”
Newton, my greatest hero! I’ve blogged about him several times, once suggesting he was the original Sherlock Holmes when as the Master of The Mint he pursues an infamous counterfeiter, then another revealing how Dr C and I have an academic connection to dear old Isaac!
