Greece, 6th century BCE Physis- the essential nature of all things Milesian school- “hylozoists,” or those
who think matter is alive- no distinction between spirit and matter
Heraclitus- continuous flow and change- dynamic and cyclic interplay of opposites- pairs of opposites as unity
But- Eleatic school- Divine Principle standing above gods and men- unique, invariable Being- indestructible substance
5th century BCE- atomists- atom as smallest indivisible unit of matter- indestructible building blocks- dead particles moving in the void- motion explained by “external forces which were assumed to be of spiritual origin and fundamentally different from matter”- origin of split between spirit and matter
This split persisted- Church and science dividing turf during Renaissance
Classical physics Descartes (1596-1650)- extreme formulation of spirit/matter
dualism- mind and matter- matter as dead and separate from the scientists- material world as huge machine- world can be described objectively without mentioning observer
Laplace- French mathematician “An intellect which at a given instant knew all the forces acting in
nature, and the position of all things of which the world consists- supposing the said intellect were vast enough to subject these data to analysis- would embrace in the same formula the motions of the greatest bodies in the universe and those of the slightest atoms; nothing would be uncertain for it, and the future, like the past, would be present to its eyes.”
Newton (1643-1727)- gravity- force between solid material objects moving through absolute space and time- connected with material bodies and acting instantaneously over a distance- particles created by God and therefore not subject to further analysis- universe made of particles set in motion, governed by force of gravity, and running like a machine since creation- giant cosmic machine causal and determinate “It seems probable to me that God in the beginning formed matter in
solid, massy, hard, impenetrable, movable particles, of such sizes and figures, and with such other properties, and in such proportion to space, as most conduced to the end for which he formed them; and that these primitive particles being solids, are incomparably harder than any porous bodies compounded of them; even so very hard, as never to wear or break in pieces; no ordinary power being able to divide what God himself made on in the first creation.”
“Absolute space, in its own nature, without regard to anything external, remains always similar and immovable.”
“Absolute, true, and mathematical time, of itself and by its own nature, flows uniformly, without regard to anything external.”
This worked to explain: the motion of solid and falling bodies, the motion of celestial bodies, the features of the solar system, the motion of fluids, the vibrations of elastic bodies, and thermodynamics.
Faraday and Maxwell- force fields- condition in space with the potential of producing a force Light as electromagnetic field travelling through space as waves,
like all EM waves At first- explained as mechanical stress in ether Einstein- no ether exists, the EM fields are physical entities in
their own right, can travel through empty space, and cannot be explained mechanically
Quantum physics- Quantum physics- atoms and atoms and other objects not solid other objects not solid anymoreanymore Atoms made up Atoms made up of of vast empty vast empty
spacesspaces-- if a hydrogen atom were if a hydrogen atom were the size of St. Peter’s Cathedral in the size of St. Peter’s Cathedral in Rome (the biggest dome in the Rome (the biggest dome in the world), the nucleus of the atom world), the nucleus of the atom would be the size of a grain of would be the size of a grain of salt!salt!
And even these particles aren’t And even these particles aren’t solid- solid- dual nature, dual nature, wave and wave and particleparticle
At the subatomic level, matter At the subatomic level, matter does not definitely exist but has does not definitely exist but has ““tendencies to existtendencies to exist,” and ,” and atomic events have “atomic events have “tendencies tendencies to occurto occur””

Heisenberg’s Uncertainty Principle- position or momentum, not both
Observer affects nature of particle & experiment- consciousness integral
A particle can only be understood in terms of its interaction with the environment- not isolated but an integrated part of the whole
“Isolated material particles are abstractions, their properties being definable and observable only through their interaction with other systems.” –Niels Bohr
“One is led to a new notion of unbroken wholeness … inseparable quantum interconnectedness of the whole universe is the fundamental reality, and that relatively independently behaving parts are merely particular and contingent forms within this whole.” -David Bohm
Entanglement- interconnection over distance- Bell’s theorem, EPR
Eastern mysticism- the universe as an interconnected cosmic web
“The material object becomes… something different from what we now see, not a separate object on
the background or in the environment of the rest of nature
but an indivisible part and even in a subtle way an expression of the unity of all that we see.”
-Sri Aurobindo “Things derive their being and
nature by mutual dependence and are nothing in
themselves.” -Nagarjuna
“The external world and (the) inner world are … only two sides of the same fabric, in which the threads
of all forces and of all events, of all forms of consciousness and their
objects, are woven into an inseparable net of endless,
mutually conditioned relations.”
-Lama Anagarika Govinda
