But when for the fourth time they had come around to the well springs
then the Father balanced his golden scales, and in them
he set two fateful portions of death, which lays men prostrate,
one for Achilleus, and one for Hector, breaker of horses,
and balanced it by the middle; and Hector's death-day was heavier
and dragged downward toward death, and Phoibos Apollo forsook him.
Of course it is happening inside your head, Harry, but why on earth
should that mean that it is not real?

The mind - brain (fate - free will) problem
George W. Gray "The Great Ravelled Knot" Scientific American October
(optimism to the study of the brain)
But consider how a "belief" in natural laws (e.g. conservation
of momentum) can justify a "cosmic" determinism, and thus the
mind-brain problem becomes a problem of fate vs. free will.

a big computer, you should be albe to predict all events"

A fundamental premise of materialistic science holds that a complete explanation
of brain function is possible in purely objective physiological and biophysical
In other words, in the world view of materialist science, real mental freedom
to act and choose is only an illusion, and the whole value-rich world of
inner subjective experience gets set aside as some kind of passive, impotent
by-product, an epiphenomenal correlate, or just an interior aspect of the
one prime material brain process.
The resultant view of human nature and the kinds of values that emerge are
All of us would prefer to think that we are more than mere puppets of environmental
reinforcement and our brain's physiology and that the inner experience we
live with most of our waking life is something real and of some material
At stake are central key concepts that directly involve fundamental convictions
regarding the nature of man's inner being, physical reality, the meaning
of existence, and related matters of ultimate concern.
...recall that a molecule in many respects is the master of its inner atoms
and electrons. The latter are hauled and forced about in chemical interactions
by the overall configurational properties of the whole molecule. At the
same time, if our given molecule is itself part of a single-celled organism
such as paramecium, it in turn is obliged, with all its parts and partners,
to follow along a trail of events in time and space determined largely by
the extrinsic overall dynamics of Paramecium caudatum. When it comes to
brains, remember that the simpler electric, atomic, molecular, and cellular
forces and laws, though still present and operating, have been superceded
by the configurational forces of higher-level mechanisms. At the top, in
the human brain, these include the powers of perception, cognition, reason,
judgment, and the like, the operational, causal effects and forces of which
are equally or more potentent in brain dynamics than are the outclassed
inner chemical forces.
Evolution keeps complicating the universe by adding new phenomena that have
new properties and new forces that are regulated by new scientific principles
and new scientific laws--all for future scientists in their respective disciplines
to discover and formulate. Note also that the old simple laws and primeval
forces of the hydrogen age never get lost or cancelled in the process of
compounding the compounds. They do, however, get superceded, overwhelmed,
and outclassed by the higher-level forces as these successively appear at
the atomic, the molecular and the cellular and higher levels.
Exam questions from 2005 - 2012 relating to this outline
In rationalizing free will, what relationship does Nobelist Sperry assign
to physical laws vs emergent properties?
physical laws still operate, but emergent properties outclass (supercede)
What issue in neuroscience was Sperry attempting to address with his notion
of emergent properties?
meaningful considerations in the meaning of human life such as free will
are impossible to reconcile with a materialist view
Nobelist Roger Sperry was optimistic that people have free will even though
materialistic science should dictate determinism. How did he rationalize
although physical laws still apply, emergent properties of assembled systems
have awesome possibilities
How does Sperry rationalize his faith in "the powers of perception,
cognition, reason, and judgment" in human action and free will?
while physical laws still apply, there are emergent properties when the
parts are assembled to the whole
"Lloyd Morgan's canon" is a fundamental statement in comparative
psychology applied to what aspect of animal behavior?
whether consciousness is needed to explain behavior
According to Sperry, "the simpler ... molecular ... forces ... have
been superceded." How then does he rationalize free will even though
"materialistic science" would explain brain function in "biophysical
because there are emergent properties of higher level configurations
