William Gilbert's science theory.
When science proper was first developing in Europe, the prevailing scholarly philosophy of nature was that of Aristotle backed by governments and religion. In Aristotle's divine universe every thing was to some extent self-acting (or 'animate') and thinking with divinely set motivations and knowledge - so that objects fell to the ground because they sought to move themselves 'to their natural place'. Gilbert saw this as involving too much irrational supposition and unable to describe the complex realities of actual natural phenomena shown in experiments to accord with invariant laws of behaviour. Gilberts theory did retain Aristotle's self-action for bodies, but only as automatic invariant law responses to emitted signals - so stones fell to the ground only with a specific acceleration in response to a specific strength and direction of gravity signals from the Earth. Gilbert postulated a robot signal-response universe basically, and saw that as very different to the Aristotle divine universe though it did retain one element of it.
Of course Gilbert had grasped the nettle of 'action at a distance' - the most difficult theoretical problem for science to explain. How could bodies, separated and seemingly with nothing in-between them, influence each other ? Besides magnetism, De Magnete did examine to some extent other 'action at a distance' phenomena including especially static electricity and mentioning gravity. It backed Copernicus on the Earth orbiting the Sun, developed more fully in his later De Mundo, adding the proposition that the Earth had a 24 hour spin because of its magnetism. But while Copernicus and other earlier scientists had not sought to develop any theory explaining the why / how of planetary motion or of any 'action at a distance', Gilbert did. Gilbert's Magnetical Science was an automatic-response-to-signals science involving different types of attraction and/or repulsion 'magnetical' signals to which different bodies responded - including for him at least 4 'magnetical' signal types being magnetic, electric charge, terrestrial gravity and inter-planetary (Newton later concluded that the last two were the same gravity). Emissions generally do show a decrease in intensity with the square of distance from their source as Kepler noted, like some action-at-a-distance forces.
Many early scientists were concerned with deriving improved description of natural phenomena, and afraid of or not at all concerned with trying to explain why nature acted as it did. Gilbert's De Magnete was mostly just taken as being the most expert scientific work describing magnetism and how it works, and only a few like Newton saw the significance of its physics theory. Gilbert saw action at a distance as based on signals that bodies emit (effluvia), and to which signals other bodies reacted automatically and invariantly as robots. His robotic response theory was commonly misinterpreted as an Aristotle animate universe theory, though it was really more an information-handling robot universe theory perhaps more advanced than the simpler mechanical clockwork-robot universe theory which Descartes later produced.
Gilbert himself did many experiments, as did Newton but not Descartes or Einstein. Gilbert centrally claimed that his experiments proved that no inactive matter existed :- "Aristotle's 'simple element' - and that most vain terrestrial phantasm of the Peripatetics, - formless, inert, cold, dry, simple matter, the substratum of all things, having no activity, - never appeared to anyone even in dreams, and if it did appear would be of no effect in nature." ('De Magnete....' Mottelay, Book 1.17 pp.69). Gilbert's 'no dead matter' physics was somewhat in line with the later 'no matter' philosophy of George Berkeley and opposed by the 'no mind' physics of Rene Descartes. Gilbert was somewhat in line with Jean Buridan (1300-1358) on motion, though Gilbert's motion is distinctly his own in concluding that his experiments proved his new theory of active bodies responding automatically in proportion to different emission signals they receive.
Gilbert basically took all bodies as being simple robots that emitted signals and responded to signals, and this was understood at least by Newton who developed it for gravity especially, though many saw his effluvia signal emissions as alchemist vapours or spirits. The key to Gilbert's theory was bodies automatically responding to whatever, and Kepler concluded that the heavenly machine is a kind of mechanical clockwork whose motions are caused by magnetic force threads. Kepler claimed in Epitome of Copernican Astronomy (1618-21) to have built his astronomy "on the Copernicus hypotheses, Tycho Brahe's observations, and the Magnetical Science of William Gilbert" - with Gilbert's magnetical science misunderstood or misrepresented as a forcefield threads science. Of course in 1600 Gilbert's ideas were alien and generally not understood correctly as there were no signal response robots built then - the most advanced machines being perhaps the mechanical clock and the compass.
Soon after publishing De Magnete, Gilbert died of the Black Death and his younger brother took responsibility for publishing his manuscript for a second book putting his wider Magnetical Science which those who understood it called Attraction Science. His brother could not get De Mundo published but soon after 1603 did manage to provide a few people with a manuscript copy, apparantly including Galileo and Kepler, and in 1651 after his death it did get published. Gilbert like Newton held a low opinion of the majority of his peers and just trusted that his own proofs and experiments would sufficiently demonstrate the correctness of his theory whatever most of his peers concluded. Gilbert's Attraction Science did gain some backing, but Descartes supporters were soon to discredit Gilbert's theory without any disproof of it, and the later 1651 publication of Gilbert's 'De Mondo' was too little too late. Descartes 'dead-matter' theory generally prevailed over Gilbert 'robot-matter' theory by name-calling and without disproving it to Newton at least. Newton's disgust at Gilbert attraction theory being dismissed by merely calling it 'occult' was shown in him saying that in that case all theories involving unseens should be called occult including Descartes' (and including Einsteins theory since nobody has seen a spacetime continuum).
Gilbert's physical universe had two types of fundamental things ;
1. Various types of particles that emitted and responded to effluvia force signal emissions, which might mean atoms or parts of atoms and maybe photons etcetera. The internal structure if any of these 'blackbox' things mattered little in Gilbert's theory, only their emission and response to effluvia signals.
2. Various types of effluvia force signal emissions, causing eg electrical, gravitational and proximity responses in some or all of the above particles.
The latter seem less easily directly detectable than the former.
Two main conclusions of Gilbert were that different types and strengths of signal had different ranges - which for magnetism could be less than an inch for a weak magnet to some miles for the Earth's magnetism - and that signal strength diminished with distance. He deduced from experiments comparing magnetism and static electricity that different types of effluvia signal emissions also had different abilities to penetrate matter, seeing low-penetration electric charge signals as material particles and high-penetration magnetic signals as non-material - so his effluvia signal emissions were perhaps in modern physics terms 'quanta'. Some have interpreted his signal range in terms of a force field, though the idea of force fields is a quite different idea requiring all space to be filled with something like an energy version of Descartes material ether. From our atmosphere attenuating with altitude, Gilbert concluded that just a few miles above the Earth was empty space containing nothing - but through which his signals including gravitation effluvia 'gravitons' could pass.
The main weakness to Gilbert's theorising came from magnetism being one of the most complex physical phenomena, so his many measured experiments could not yield him the simple mathematical laws that Newton was to later develop in applying Gilbert's theory to gravity. He also seems to have had some distrust of mathematical deduction as being mere logical philosophising as against experimental proof science. A couple of bits of Gilbert were disproved by later experiments, but were entirely inessential to his theory. Kepler unintentionally showed that good mathematics could be successfully derived even using a poor explanation physics, but not until Newton was Gilbert's 'attraction theory' properly mathematised.
Despite Gilbert disproving Aristotle many times in his works, Gilbert's theory was labeled by many physicists as 'Aristotelian' god-derived - and was rejected in favour of the limited-god Descartes mechanical-robot science (fully published by 1644) but maybe akin to throwing out the baby with the bath water ? Information handling robots are a more modern technology than mechanical robots, and modern information theory is now doing much work that is basically along Gilbert signal theory lines, though without any great impact on physics theory as yet. Despite the almost universal use now of televisions and mobile phones all acting in response to remote emitted signals, which perhaps at least partly confirms Newton's view that Gilbert signal theory was at least plausible ? But the majority of physicists still claim that action at a distance is impossible - when most people know it IS possible and works by SIGNALS emitted and responded to as Gilbert concluded that magnetism, electric charge and gravity work. Gilbert termed those natural emitted signals 'effluvia' - from Latin at the time generally taken as meaning 'non-visible characteristic emissions from bodies such as their smells'. But in his preface to De Magnete did clearly state that his use of words often involved new scientific meanings for them.
The actual observed difference between magnetic behaviour and gravitation behaviour is substantial, so that producing one simple theory to cover both is a substantial problem.
Hence magnetism involves attraction, repulsion and orientation affects, while gravity involves only one simple attraction affect.
Gravity being basically simple could easily seem to suit a simple Descartes mechanical push theory, which was very difficult to apply to magnetism.
But magnetism being more complex perhaps more suits a Gilbert signal response theory, which also was easy to also apply to gravity as attraction theory as Newton showed.
And notably gravitational and electromagnetic forces have some common aspects that Gilbert signal response theory handles well. They both have directionality though it may be only directionality relative to another object, and their action also seems to involve a mutuality relative to another object. In fact these forces may well have no objective existance for one object alone, in line with William Gilbert's signal-response theory of forces ?
Some like Einstein followed Descartes basically by taking gravity as being fundamental, and taking magnetism as being an inessential of less importance to physics theory. Though in science all well confirmed facts are basically equal, Newton did little to oppose the magnetism does not matter position.
But the fact that magnetic and electric charge forces give BOTH attraction AND repulsion behaviour, does strongly suggest that the force of these forces at least is NOT in the force itself but in bodies responses as in Gilbert's signal response theory.
For comparison with other physics theories, Gilbert's three laws of motion would be ;
1. Every body will remain at rest, or in a uniform state of motion unless effluvia signal emissions act upon it.
2. When effluvia signal emissions act upon a body, it accelerates itself proportional to the signal strength and inversely proportional to the mass of the body and in the direction required by the signals.
3. Every effluvia signal action evokes an equal and opposite reaction.
Gilbert's theory might maybe be strengthened with a few additions that would basically make it a guage bosons particle exchange theory such as some modern particle physicists favour ;
1. Bodies emit various effluvia with speed of light velocity in response to various effluvia being received by them.
2. All motion and other natural phenomena are caused by this process (including seemingly causeless radioactive decay).
3. Effluvia are conserved.
4. All bodies are aggregates of effluvia.
Then we might have the basis of a quantum mechanics physics without fields or continua, or of a no-ether Descartes particle push physics - without fanciful corkscrew-particle-push or boomerang-particle-push attractions ? Maybe a high-reaction gravition causing the emission in the same direction of a particle pair of a similar low-reaction graviton plus another high-reaction particle (normally multi-directional) giving the gravity momentum effect ? Whatever it would mean, that physics would be about how many different types of effluvia exist and their properties, how many different types of effluvia-aggregates exist and their properties including what influences effluvia aggregation and dis-aggregation ? And maybe unlike mass, charge and spin could be just signal response properties ?
One apparent difference between Gilbert-Newton signal attraction theory and Descartes push theory is on 'action and reaction are equal and opposite'. Though Gilbert and Newton proved that this did hold for attractions, it may seem that a push must give an equal effect while a small signal might give a big effect. But this apparent problem can also occur in mechanics and can be fully resolved with lever, trigger and conversion (eg E=Mc2) effects.
And if particles like neutrons are themselves complex systems, then a graviton signal might trigger a series of events including eg neutrino emission that actually produce motion responses ?
The supposedly separate two processes of force-production and acceleration-by-force, may
actually be basically one process - ie. bodies in Gilbert theory terms maybe basically respond to
external forces by accelerating themselves by emiting their own forces.
This could give a natural quivalence having a wider cover and making more sense than
Einstein's little Equivalence Principle applying only to gravity. Supporting this is Gilbert and Newton often positing the mutuality of forces between multiple bodies, and as we are in a multiple body universe there can maybe be no proof that one single isolated body would have any force of gravity or any other force ?

There should be freely available English or translatable online versions of Gilbert's two major publications,
his 16OO "De Magnete, magneticisque corporibus et de magno magnete Tellure, physiologia nova" ('A New Science of the magnet, magnetical bodies and the great magnet the Earth')
and his 1651 "De Mundo Nostro Sublunari Philosophia Nova" ('A New Science of our Sub-lunar World, or A New Science of everything under the moon'),
but somehow neither seem available online. We will try to put more of it online on this website soon, but for now our Gilbert sections have only English extracts and full online Latin image versions or links.
Gilbert's anti-philosophy/reasoning and pro-experiment/experience position was reflected around 1670 in 'Satire Against Reason And Mankind' by John Wilmot Earl of Rochester though that interesting work was maybe just anti-science ant-religion and anti-government ?
