for granted: In the beginning were the
particles and the impersonal laws of physics; life evolved

particles that randomly created everything
by... exploding.......

Certainly many believe that a man can search out and grasp the Truth just as well, creatively express the Beautiful just as well, vitally perfect the Good just as well, even if, in order to win some advantage in the world, he was secretly a little unfaithful to himself, even if he did shift the boundary stones of his inner life a
particle by Just a shade less scrupulousness, so that even though he had won this material advantage
by doubtful means, yet he «can truly work
for the Good, the Beautiful, and the True.»

for the elusive God
particle (they won't find it); evangelical sports superhero and Denver Bronco quarterback Tim Tebow will continue to be both an inspiration to the faithful and an object of scorn to skeptics (he will be watching, not playing in, the Super Bowl); at least one well - known religious leader or leading religious politician will be brought down
by a sex scandal (let's hope all our leaders have learned a lesson from former Rep. Anthony Weiner and stay away from sexting); and the «nones» - those who don't identify with one religion - will grow even more numerous and find religious meanings in unexpected places (what TV show will become this season's «Lost»?)
But, as Bohm points out, such a position can not stand up to critical analysis,
for the molecules studied
by biologists in living organisms are constituted of electrons, protons and other such
particles, from which it must follow that they too are capable of behaving in ways that can not be described in terms of mechanical concepts.

Stapp is not suggesting that the actual results of spin measurements

particles will be affected
by the choice of an axis
for measuring the spin of the other member of the pair — even if this choice is made after the
particles have ceased interacting.
That idea worked well
for the postulated hard
particles of pure physics; but it certainly leads to mischief when it inspires the notion of supposedly separate «sovereign states,» each within its own body (a «body politic») marked off from the rest
by the sharp lines defining their collision.
According to this rather common - sensical principle, if two physical systems (
particles,
for example) have ceased interacting or have never interacted, neither is affected
