Ostrowick 2012 and text discussion
Validity: The premises are directly stated in the source passage as reasons supporting the conclusion that simplicity is not always reliable, and they do rationally support (not attack) that conclusion—though the argument is labeled as an "attack" on Swinburne's reliance on simplicity, the premises rationally establish the stated conclusion, and the argument is clearly present in the passage.
Confidence: Explicitly raised critical questions about Swinburne's reliance on simplicity.
