Second Midterm Flashcards
Two steps of modern cosmological arguments
- Argue for existence of necessary/self-existent being
- Identification stage
First and last step of Reichenbach’s cosmological argument
- A contingent being exists
- A necessary being exists
Is cosmological argument full or partial
Full
Problem w/ premise cosmological “What explains the existence of this contingent being must either be solely other contingent beings or include a non-contingent being
“Being” - if modify to “thing” (law/principle), weaker conclusion necessary thing exists which might not be a being
Commentary on “A contingent being exists”
Granted there are beings, denying premise 1 would affirm the conclusion
Commentary on “The cause of its existence is something other than the contingent being itself”
Rules out self-causing beings, seems secure, would have to explanatorily precede itself
Alternatives to “contingent beings alone cannot cause the existence of another contingent being”
chains terminating in contingent being (that is brute)
Chains that are circular (not plausible)
Chains that are infinite
Hume/Edwards Priniciple
Sufficiently explaining each/every part of something sufficiently explains existence of the whole
Arguments against Hume/Edwards Principle
- Reducing infinite causation to circular causation (sees illegitimate to explain collection of eggs w/ collection or chickens); whole infinite series still requires explanation
- Cannonball’s causeless flight
Two versions of cannonball’s causeless flight
- Cannonball at rest at t0, t1l; trajectory every time in between. Can explain each stage of trajectory even if cannonball not shot
- Canon ball does not exist at t0, but exists at every moment after; existence of cannon ball popping into existence sufficiently explained
One possible way to justify premise “This contingent being has a cause of its existence”
PSR
Principle of Sufficient Reason
For everything that exists, there is a sufficient reason for its existence; denies brute facts; universe is intelligible/things have explanations
Problem with PSR
Modal collapse
Modal collapse argument
If the PSR is true, then there are no contingent facts (necessitarianism)
How could we save Premise 2 from modal collapse
weaker intelligibility principle that doesn’t have contrastive explanation for everything but still sufficient to explain what we witness
More on Buridan’s ass
With a more demanding PSR, donkey could not go anywhere
But still ruling out many other possibilities, so intelligibility still preserved
Why is Buridan’s ass advantageous to cosmological argument 1
Found explanatory principle that doesn’t require fully contastive explanation
Brute Facrt view
Explanation for existence of universe of contingent beings terminates in a brute fact; or there is infinite chain of contingent beings, and that chains’ existence is brute fact
Why might theist want to rule out necessarianism?
Maybe free will, theological determinism; maybe limiting if God forced to create universe
What is response to partial intelligibility/brute fact view
Maybe not rational in maintaining trust in cognitive facilities and in rejecting skepticism
What is a reason to doubt a skeptical universe and say common sense view more antecedent probability
If thought there was a necessary ordering toward valuehat
What is the common sense view
The universe you take yourself to inhabit (vs. skeptical universe)
Examples of skeptical universes
5 minute old universe
Laws of physics normal, then shift radically
Boltzmann Brains - particles accidentally come together, really just popped into existence
Sprase consciousness
Why would brute fact lead to skeptical universes
If skeptical universes all possible, then no reason there’s ovne over the other; common sense universe being simpler would not carry weight
Why is skeptical view so powerful
Skeptical view predicts evidence just as well as common sense view; and pre-evidential probability is just as high, so no basis to deny skeptical view
One way to argue for identification stage/definition
Perections don’t just happen; good qualities must be there from the beginning, so first cause must be personal
Since first cause is necessary, reason to deny it has arbitrary features; supports attributes resembling omnipotence and omniscience (no arbitrary limits on those things) and simplicity (no composition of parts that didn’t have to exist together)
Maximalism
Every possible universe exists
Pros/cons of maximalism
Pro: theoretically simple/non-arbitary/explanatorily powerful
Con: leads to radical skepticism
Axiarchism
fundamental ordering toward good
Three steps of Kalam cosmological existence
- Whatever beings to exist has a cause of its existence
- The universe began to exist
- Therefore, the universe has a cause of its existence
A posteriori defintion
Begins w/ premises about things that exist
Typical conclusion of teleological arguments
Some very powerful designer accounts for natural world; still needs identification stage
Basic teleological argument
- Fine-tuning is more likely under design than not
- Fine-tuning data tell us that life was extremely unlikely to occur just by chance
- Evidential significance of life boosted
Illustration of teleological argument
Randomly generated pixels; strength of evidence dependent on how likely it could obtain by accident
Example of observer selection effect
20 sharp shooters its, likely that thy planned it; but only universe you could have observed since alive
3 objections to fine-tuning argument
- Why think a designer would care about life
- Observer selection effect
- Non-intentional orientation
- many universes/cycles/regions (we’re in a hospitable region, most of other places not fine-tuned)
- Projections of specialness
- Have no way of assuming how unlikely probabilities are
Most plausible response to teleological argument q
Multiple universes
Hume’s “who designed God?” utility and implications
Response to teleological argument: complex configuration of reality in God’s mind calls out for explanation just as much as physical configuration of matter , so appealing to designer not explanatorily powerful; just pushes surprise back
Hume’s response to the necessary being theist
Maybe material reality is necessarily ordered toward value w/out direction of an intelligence being
How does Hume respond to Brute Fact theist/response
Material order exhibiting valuable properties by chance is no more or less likely than change existence of a divine being; maybe divine being is more simple, but questionable whether that is simpler since maybe God must be as complex as the universe
Two forms of argument of evil
Logical argument: given existence of God, existence of evil lis a conceptual impossibility
Evidential argument: evil if can’t be logically proven God/evil are incompatible, nature of evil we observe is highly improbable given God’s existence
Platinga’s proposed premise:
Everyone suffers from transworld depravity, so God created world w/ evil because it was price to create a world with significant freedom and moral good
Logical problem - Plaintga
- God is omnipotent, omniscient, wholly good
- Such a being would eliminate every evil it can properly eliminate
- If God is such, then he can properly eliminate every evil state of affairs
- Evil exists
