Study Notes on the Existence of God - Chapter 6

Definition: Cosmological arguments seek to answer the fundamental question: Why is there something rather than nothing?
Conclusion: Typically, these arguments posit that God is the reason why there is something rather than nothing.

Historical Context: Aquinas was a medieval philosopher from the 1200s.
Key Claim: Everything that exists has a cause, leading to the necessity of a first cause.
- This means if one traces back the causes of anything, they will eventually reach a first cause — which Aquinas identifies as God.
Structure of Argument:
1. Everything that exists has a cause.
2. Therefore, everything with a cause must have a first cause.
3. The conclusion is that the first cause is God.

Objections Summary: While the argument supports the existence of a first cause, it does not directly establish its identity as God, leading to a perceived failure of the argument.
- Critical Leap: Transitioning from a first cause to identifying this cause as God requires more than just the premises provided.
Historical Response: Critics assert that the project of rational theology has failed because it does not lead directly to the specific conception of God desired (i.e., the Abrahamic God).

Aquinas' Perspective: Aquinas' aim may simply be to establish a first step toward rational proof for the existence of God.
Medieval Mindset: Medieval thinkers believed that the universe was rationally ordered, supporting the effort to logically prove God's existence.
Rationality: If there is a rational order, it implies a rational being as a creator.

Concerns with Infinity: A potential objection is the possibility of infinite chains of cause and effect, which Aquinas presumes is not the case.
Response from Apologists: Even if an infinite chain exists, it may still require a cause for that chain, as discussed by Samuel Clarke.

Skeptical Consideration: Why must there only be one first cause? Could multiple causes exist?
Implications of Multiple Causes: The idea that complex events can have multiple antecedents challenges the uniqueness of Aquinas' first cause.

Three Main Divine Attributes:
- Omniscience: Knowledge of everything.
- Omnipotence: The ability to do anything that is logically possible.
- Omnibenevolence: Being morally perfect or all-good.

Structure of the Kalam Argument:
1. Whatever begins to exist has a cause.
2. The universe began to exist.
3. Therefore, the universe has a cause.
Critical Remarks: The Kalam argument can lead to the recognition of a cause but does not directly affirm specific divine attributes without additional work.

Potential Conflicts: Claims regarding causation are challenged by modern scientific findings, such as those seen in quantum mechanics (e.g., events like radioactive decay that occur without causal explanation).

Comparative Obsolescence: Cosmological arguments can seem antiquated compared to teleological arguments that align more closely with modern scientific understanding.
Teleological Arguments: Unlike cosmological arguments, teleological arguments are perceived to carry more weight in contemporary discourse.

Definition: Teleological arguments assert that the universe exhibits design and seek to explain that design. It argues from the observable complexity and order of the universe to the necessity of a designer.
Characteristics:
- Arguments that consider apparent design in the universe challenge us to recognize possible intelligent design.

Analogical Design Argument:
- Premise 1: The universe has parts that fit together like a machine.
- Premise 2: Machines have designers.
- Conclusion: Therefore, the universe has a designer.
William Paley's Watch Analogy:
- Paley posits that finding a watch on the beach compels one to conclude that it was designed. If a watch, which is far simpler, requires a designer, then a more complex universe must also imply a designer.

Functionality of Parts: Questions arise regarding what these various parts function as and whether such functions remain consistent.
Mechanistic View vs. Modern Physics: Modern physics, especially quantum mechanics, reveals complexities that do not align with simple mechanistic explanations.

Formulation:
1. The universe exhibits apparent design.
2. The best explanation for this apparent design is that a supernatural being designed it.
3. Therefore, it is probable that the universe was designed by a supernatural being.
Methodology: It follows the principle of the inference to the best explanation, a common scientific reasoning pattern.

Application: According to Occam's Razor, we should not multiply entities beyond necessity. If simpler natural explanations account for observations, we should prefer them over more complex supernatural hypotheses unless compelling evidence suggests otherwise.

Evolutionary Theory: The discussion highlights how evolutionary biology provides alternative explanations for observed phenomena traditionally attributed to intelligent design.
Debate on Best Explanations: Elevating the design argument requires it to compete on equal footing with science by consistently meeting evidentiary standards.
