Final answer:
Cultural relativism recognizes the diversity of cultural norms and suggests that truths can vary across different cultures, affecting the universality of truth and the ability to critique or reform cultural practices. It presents challenges by opposing the idea of absolute truths and creating potential self-refuting contradictions.
Step-by-step explanation:
Cultural relativism acknowledges the diversity in different cultures' behaviors, thoughts, and emotions, which are learned from previous generations. It suggests that there are various truths across different cultures and this diversity extends to moral and ethical standards. Cultural relativism claims that an action might be moral in one culture and immoral or illegal in another, thus making truth relative and challenging the notion of a single universal truth. Therein lies the problem: it creates challenges for universal criticisms and assessing the validity of different cultural practices. Moreover, cultural relativism raises concerns about the absoluteness of knowledge and truth, and how differences in belief systems should be addressed educationally.
