Explanation
Reductionism in the context of testimony is a philosophical stance that argues testimonial knowledge is not a distinct or independent source of knowledge. Instead, it is reducible to other foundational sources, such as perception, memory, or inference. According to reductionists, for a belief based on testimony to be justified, one must have positive reasons for thinking the speaker is reliable. These reasons themselves must be grounded in non-testimonial evidence.
Reductionists believe that accepting testimony requires prior justification derived from experience or other reliable epistemic sources. For instance:
- Global Reductionism states that justification for testimonial belief depends on having general positive reasons for believing testimony as a whole is reliable.
- Local Reductionism requires specific positive reasons for believing the individual speaker’s testimony in a particular instance.
This contrasts with anti-reductionism, which holds that testimony can be a basic source of knowledge and does not require independent justification unless there are reasons to doubt it.
The correct answer, B, precisely captures this view: the rationality of believing testimony depends on the rationality of other sources of belief.
