More Nagelisms

I was perusing blogs awhile back (actually a few years!) when I came upon this quote from Nagel's Mind and Cosmos. Rather than consulting my notes it is just easier to re-quote it here.
First, that the non-teleological and timeless laws of physics--those governing the ultimate elements of the physical universe, whatever they are--are not fully deterministic. Given the physical state of the universe at any moment, the laws of physics would have to leave open a range of alternative successor states, presumably with a probability distribution over them. Second, among those possible futures there will be some that are more eligible than others as possible steps on the way to the formation of more complex systems, and ultimately of the kinds of replicating systems characteristic of life. The existence of teleology requires that successor states in this subset have a significantly higher probability than is entailed by the laws of physics alone--simply because they are on the path toward a certain outcome. Teleological laws would assign higher probability to steps on paths in state space that have a higher "velocity" toward certain outcomes. They would be laws of the self-organization of matter, essentially--or of whatever is more basic than matter. (pp. 92-3)
This is a good summary of Nagel's attempts to reintroduce teleology into the natural universe. Nagel realizes that neo-Darwinism is a fatally flawed theory. The gist of the argument is that naturalism has to reintroduce final causes. Blind chance and mechanistic evolution don't get it. Mixed up in the argument is the typical atheist reliance on chance and probability. The motions of matter are not deterministic.

Okay, for the sake of argument, let's grant that. As theists we deny that the source of "probability" is what the atheist claims it to be -- an ultimate irrational residue of lawlessness. A world in which things happen for "no reason!" But back to the technical issues.

The probability distributions of quantum field theory can be computed with some very precise results for things like scattering amplitudes,half-lives, branching ratios and the like. These probability "amplitudes" are all functions of the basic properties of the physical systems being modeled. And, here's the point: the amplitudes have no teleological aspect. All of physics exhibits non-teleology. The future state(s) of the universe are solely determined by the present state, past and future are irrelevant. This principle falls out rather neatly from the principle of least action -- a very general principle from which all equations of motion can be derived given a Hamiltonian (think, "energy") or Lagrangian function that depends on the constituents of the system and their configurations. Moreover Nagel's plan is to require "... that successor states in this subset [those favoring replicating life] have a significantly higher probability than is entailed by the laws of physics alone--simply because they are on the path toward a certain outcome."

The nail in this coffin is that Nagel imagines some non-physical laws that must alter half-lives, branching ratios and so on, along the way.  After all, according to the atheist myth of macro evolution, the journey to replicating life is via small steps with compounded probabilities. We ought to be able to see such evidence in pre-biotic chemical reactions.  

Embracing such non-physical laws is to accept a new dualism and to abandon the pillar of monism in the atheist's philosophy. Paradoxically, the positing of extra-physical (should we say supernatural!) properties seems not to worry Nagel's new born "naturalism."

Inexplicable! And That's No Lie!

Every fact of human experience is proof of theism and, therefore, a disproof of atheism and, thereby, also of agnosticism. This is the transcendental argument for the existence of God -- God exists because of the impossibility of the contrary.

The other day I was pondering the slogan that some people make about our former President, "Bush lied, people died."

But what is this human act called "lying"?

First, lying requires intentionality. A lie is to knowingly utter a statement contrary to the truth in order to deceive. In this regard, the slogan above is a claim that Bush intentionally said there were WMD in Iraq, while he knew there were none.   Thus, the slogan is an extraordinary claim since most of the world's leaders and intelligence agencies believed Iraq possessed WMD. Regardless of why the nearly worldwide agreement on intelligence data was faulty, without that moral dimension, speaking or believing a falsehood is not a lie -- it is merely an error.  Otherwise, students answering examinations incorrectly are the biggest group of liars in all of creation.

Moreover, lying is a sin!  Sin is the breaking of God's commands.  But for atheists, lying could not be considered a sin, since to them, there is no God. In that case lying becomes "good" or "bad" according to situational relativism.  Of course "good" or "bad" is not absolute to the atheist -- "good" or "bad" means "good" or "bad" in terms of consequences for oneself or the conventions of one's social group.

For many of the godless, lying is a means to an end.  But this brings us to the crux of the problem for atheists.

The laws of physics have the property that they have no memory of the past and no goal for the future.  They are "ignorant" of the past and "blind" to the future (to use the usual anthropomorphizing of an insensate material universe) . The atheist worldview of materialism embodied in the laws of physics states that the future depends only upon the state of reality now.  This implies two things:
  1.   There is absolutely no teleology in physical systems -- there is no goal-orientated direction.  
  2.   The future is compelled by laws of physics channeled via irrational quantum chance.
This means that if man is purely a material system, as atheism claims, there can be no "means to an end."  And to the atheist, since man is quantum mechanically predetermined -- and his acts ultimately produced by irrational randomness -- even describing lying as a "means to an end" is inexplicable. 

It is further inexplicable that man as an absolute physically determined system can utter a false description of reality in order to deceive and attempt to alter, influence or otherwise elicit a desired response from other humans to achieve a self-centered goal.   Man's mental states, being no more than mere results of "random" quantum mechanical fluctuations, can then have no causal efficacy -- they cannot cause electrons to swerve from their paths. Mental states are to the physical brain as a person's shadow is to the body.  As a result "mental" states cannot alter physical brain states, just as the body's shadow cannot produce body motions.

"Lying" as an immoral act rests upon the presuppositions of mental causation, logical laws, human free agency, intentionality, and moral laws, none of which would exist in a purely physical reality.

The very act of lying is impossible and inexplicable in a Godless reality. So then, the human act of lying is proof of God. On the other hand, the atheist believes in things -- such as lying -- that his fundamental presuppositions deny.  Such are the contradictions of atheism and its self-refuting pretensions.
