Final answer:
Philosophers debate the objectivity of moral values and the role of certainty in knowledge, arguing from different perspectives like moral realism and skepticism. While some assert the existence of objective moral goods, others emphasize the sentiment-based nature of morality. The fact-value distinction is also challenged, integrating values into scientific practices.
Step-by-step explanation:
The question poses a philosophical inquiry about the nature of moral values and the tension between accepting uncertainty or embracing certainty. It queries whether it is pragmatically beneficial to believe in objective morality and certainty in various aspects of life, even if such beliefs may be considered delusional or against the evidential truth. Contemporary philosophy often grapples with the objectivity of moral values. Philosophers propose lists of objective goods that contribute to well-being, such as health, knowledge, and virtuous living, which could be seen as objective aspects of morality. However, skepticism about morality stems from its normative nature, which asserts what ought to be the case without empirical evidence. Invested philosophers such as David Hume argue that morality is based on sentiments rather than facts. Meanwhile, moral realists contend that there are moral facts which provide an objective basis to our ethical judgments.
Regarding certainty and knowledge, there are perspectives that suggest one does not need absolute certainty to possess knowledge. Philosophy employs argumentation to challenge concepts like the 'certainty' theory of knowledge. This discussion extends to skepticism about the existence of God, where figures like Blaise Pascal argue for faith in the absence of proof. Yet, skeptics point out that insufficient evidence for moral or religious claims leaves room for doubt. Finally, objections to the fact-value distinction present an interesting crossroads, where philosophers like Hilary Putnam argue that value judgments are inherent in scientific reasoning too, challenging the traditional separation between facts and values.
