Final answer:
The ability to articulate reasons for decisions and actions enables critical evaluation and analysis, particularly in moral reasoning, rather than proving universal moral truth, the infallibility of moral thought, or negating moral skepticism.
Step-by-step explanation:
The question enquires about the role of reason in explaining our moral decisions and actions. The ability to offer reasons to support our decisions and actions allows us to critically evaluate and analyze decisions and actions. It is through this critical evaluation that we gain insight into the reasons behind moral claims, which often rest on arguments grounded in value claims. While moral skepticism doubts the possibility of proving normative claims, the use of reason has been crucial in moral philosophy, especially during the Enlightenment where philosophers like Kant highlighted the importance of rationality in establishing moral laws that could be universally applicable.
Moral theory and moral reasoning are tied closely with our ability to rationalize and offer justifications for our actions. Immanuel Kant and other Enlightenment thinkers focused on reason as the means to justify moral principles. Hence, the claim that our capacity to offer reasons is evidence of our ability to engage in moral discourse and reach conclusions concerning what is morally permissible or obligatory.
It is also important to recognize the impact of moral skepticism, which questions our ability to know moral truths, and alternatives to rationalistic ethical theories that do not rely solely on reason. Regardless, the ability to discourse about morality is crucial for not only ethical debates but for the coexistence of individuals within communities.
