Final answer:
Bertrand Russell's critique using 'golden mountains' is challenged due to a confusion between universal generalization and instantiation, causing misinterpretation of existential import of conclusions, as he drew inference from non-existing entities.
Step-by-step explanation:
The critique of Bertrand Russell’s argument concerning Aristotle's logic on universal affirmative statements using “golden mountains” highlights a potential flaw. This flaw can be attributed to Option (a), which states that Russell fails to discern between universal generalization and universal instantiation, leading to a misinterpretation of the conclusion's existential import in the context of the example.
The term golden mountains is used metaphorically to illustrate an argument that claims the existence of a category without actual instances. Russell's argument may be critiqued for assuming the existence of entities (golden mountains) that do not actually exist, thereby questioning the validity of inferences drawn from such premises.
The logical fallacy lies in assuming that because the premises logically entail a conclusion, the actual entities must exist, which is not necessarily the case.
