Final answer:
The question relates to the debate between moral realism and anti-realism, and whether the principles from Zalta could contribute to reasoning about concrete moral questions. While moral realism argues for objective moral facts, anti-realism sees morality as more subjective. The relevance of abstract principles to practical ethical reasoning remains a complex philosophical contention.
Step-by-step explanation:
The principles from Zalta that are invoked in a discussion about moral realism and anti-realism, particularly in the context of abstract objects, connect to the broader debate on the ontological status of moral values. Moral realism argues for the existence of moral facts that hold objectively, whereas anti-realism posits that moral values are not factual and are perhaps more subjective. This contrast is evident in the critique moral realists have against anti-realists - if moral values are purely subjective, it creates a sense of arbitrariness and challenges the legitimacy of moral reasoning, leading to a potential moral and ethical relativism.
Moreover, the question raised about whether these principles can contribute to reasoning about concrete moral questions ponders the applicability of Zalta's principles to everyday moral dilemmas. While moral skepticism can lead to relativism and pessimism, moral realists seek an objective foundation for morality that can guide actions within communities. The Presentist approach and the Theory of the Forms may offer insights into the presence of universal moral principles, as alluded to by historical figures like Plato, who sought these timeless truths.
Furthermore, notions such as Fundamentality: The One and the Many reflect the ontological discussions where monism contrasts with pluralism in determining the 'real.' Philosophers have also raised concerns over moral principles potentially restricting divine omnipotence, signifying the gravity of moral absolutism if morality has an ante rem status. The balance between foundational principles and practical ethical decision-making is also considered, with figures like Sir William David Ross suggesting that prima facie duties permit a nuanced approach to competing moral obligations.
Ultimately, while moral facts might not contribute directly to concrete ethical deliberations, understanding the theoretical frameworks that support or refute the objectivity of morality is crucial for developing a coherent moral philosophy. The exploration of whether abstract principles can ground an ante rem form of moral realism illustrates the complexities of bridging metaphysical theories with practical ethical reasoning.
