Final answer:
Theists argue that moral truths are objective and connected to a divine source, contrasting with moral skepticism that suggests moral values are subjective and culturally influenced. Option a.
Step-by-step explanation:
The theists argue that moral truths are objective and rooted in a divine source. This is under the broader discussion of moral realism, which contends that there are certain moral facts that are objectively true. In contrast, moral skeptics highlight the subjective nature of moral values, arguing against an objective basis for morality and emphasizing that moral values are a product of human sentiments rather than facts. Theists, particularly in various religious traditions, often consider moral values to come from divine commands or sacred revelations, tying them directly to the existence of a higher power or God.
Moreover, there are philosophical challenges within the theistic perspective, such as the Euthyphro problem, which questions the dependency of moral goodness on divine commands. This debate navigates between whether something is good because God wills it, or if God wills it because it is inherently good. Nevertheless, the core stance of theists in regards to moral truths remains that they are not merely subjective or culturally relative, but are firmly grounded in the existence and nature of the divine.
