What I'm talking about, Lagboltz, is not "religious doctrine" but simple natural law philosophy, for which you still haven't furnished an objection that isn't predicated on question-begging utilitarianism.
I'm perfectly comfortable acknowledging that natural law theory, followed to its logical conclusion, will produce material suffering, discomfort, and unhappiness on this earth. Sexual morality alone would produce such discomfort, since, natural law being a virtue-based system, would require self-control rather than the constant gratification of one's lusts. I don't view this as a problem because I don't see that maximizing pleasure and minimizing pain is the chief moral good -- again, because I'm not a utilitarian, because I'm a natural law theorist, because natural law is rationally superior and I have yet to hear a logically sound objection to it.
Aquinas's proofs predate Newtonian mechanics by 4 centuries. Even so, Thomas Aquinas would arguably have some merit via Newton. Where the arguments of Aquinas completely fall apart are a result of Quantum Mechanics. Cause and effect are much more complex phenomena. Also the interaction of bodies are remarkably different. The reason TA fails to understand nature is that QM is notoriously counterintuitive. What follows are excerpts from TA's arguments and how they are invalid by today's QM.
Proof 1:
TA: Only an actual motion can convert a potential motion into an actual motion.
QM: Spontaneous decay of isotopes violate his assertion.
TA: Nothing can be at once in both actuality and potentiality in the same respect (i.e., if both actual and potential, it is actual in one respect and potential in another).
QM: "Schrodinger's cat" illustrates the problems of this assertion. Many phenomena can simultaneously exist in multiple states.
Several other points in proof 1 are also outdated.
Proof 2:
TA: Nothing exists prior to itself.
TA: If a previous efficient cause does not exist, neither does the thing that results.
QM: Spontaneous creation of virtual particles. This real effect gives neutrons some of its properties.
Proof 3:
TA: ...
3. Therefore there could have been a time when no things existed.
4. Therefore at that time there would have been nothing to bring the currently existing contingent beings into existence.
5. Therefore, nothing would be in existence now.
...
QM: His conclusion 5 here doesn't follow from the 3 and 4 because of spontaneous virtual particles.
Proof 4:
TA: Various physical measures (heat) and nonphysical measures (nobleness) have a maximum or minimum.
He says the maximal measure is the cause of all other lesser measures. This makes no sense in today's physics. The current concept of cause has no relation to a general extremum condition.
Furthermore the conclusion that he gives is an inductive generalization. i.e. an informal fallacy.
Proof 5:
TA: ... natural bodies work toward some goal, and do not do so by chance...
QM: This is totally wrong in QM. The wave function which is the basis of all interacting bodies describes probabilities (chances) of interaction, and never give a Newtonian determinism of motion that TA assumes.
One might argue that Newton's physics are good enough for the world of TA, but he is going well beyond common worldly phenomenon to the extent that he gives declarations about ultimate concepts. QM is necessary in the ultimate understanding of the universe and must be taken into account.
Finally TA's five proofs are not proofs of God at all. They are definitions of God. His final sentences of the 5 proofs are:
1. ...this everyone understands to be God
2. ...which everyone gives the name of God
3. ...this all men speak of as God
4. ...and this we call God
5. ... and this being we call God
I can see now why you were so confident in the "not arrogance because it's true" argument -- because TA is defining God to exist.
Assert x is true. Define God = x. Therefore God exists (under the constraints of x.) It's a simple logical tautology.
My QM arguments are that x has not been shown to be true. Therefore there is no proof of God.
On the other hand, I can't help but notice you didn't respond to the hypothetical scenario I posited above regarding the organ-harvesting physician. I suppose that stands to reason. After all, a world full of people murdered in the name of the "common good" is exactly what a world run consistently on your and Openmind's consequentialist ethics would look like.
The organ-harvesting physician would not want to go to jail and would conduct himself to that end. I mistakenly thought it was a rhetorical question. Please don't assume you understand my consequentialist ethics and proceed to reprimand me.
