Final answer:
A particularist can counter skepticism by emphasizing the importance of context and justification for knowledge claims, noting that while particularism is flexible, it still requires responsible, justified beliefs.
Step-by-step explanation:
A particularist could respond to the skeptical objection about potential abuse by emphasizing the role of contextualism and justification in the particularist framework. Particularism doesn't advocate for arbitrary claims to knowledge; rather, it holds that knowledge is often context-sensitive and that what counts as justification may vary depending on the situation.
For instance, less justification may be needed for everyday claims, while more rigorous standards are necessary in areas like science or law. Moreover, the mere possibility of abuse does not undermine the validity of particularism, just as potential misuse of skepticism (e.g., to support radical doubt or denialism) doesn't inherently discount skepticism as a philosophical standpoint.
A proper understanding of particularism would involve recognizing the responsibility that comes with asserting knowledge claims, including the need to provide justification when appropriate.
