Final answer:
Olson denies the major and the minor of the conditional syllogism in response to argument 2 against animals, arguing that non-intelligent creatures can still be compared to those with reason.
Step-by-step explanation:
In response to argument 2 against animals, Olson denies the major and the minor of the conditional syllogism. He argues that the deduction from intelligent creatures to all creatures, assuming that non-intelligent creatures cannot be compared to those with reason, is an unsupported assumption. Olson suggests that the surplus of good in non-intelligent creatures may outweigh the surplus of evil in rational creatures.
