Final answer:
Friedrich Nietzsche's work focuses on the concept that there are no absolute goods or evils, proposing that moral judgments are tied to power dynamics rather than universal truths. His critique of traditional morality and the genealogy of moral concepts from social class dynamics forms the basis of moral relativism and the subjective interpretation of ethics.
Step-by-step explanation:
The exploration of the concept that there is no absolute good or bad is a central tenet in the philosophy of Friedrich Nietzsche. Nietzsche's texts, such as Beyond Good and Evil and On the Genealogy of Morality, critique traditional morality and propose a perspective where moral judgments are not universal but tied to perspectives of power. The idea that there is no absolute moral truth aligns with philosophical relativism and Nietzsche's deconstruction of moral concepts from their origins in the dynamics between social classes.
A notable contribution of Nietzsche is his distinction between the concept of 'good and bad' and 'good and evil', where the former refers to excellence or merit and the latter arises from reactions of the weak against the strong, culminating in moral indignation. Examination of these ideas might begin by understanding the transformation of the term 'noble' from a designation of social class into an ethical good through the influence of Judeo-Christian philosophy.
Without the absolute, ethics become a subjective endeavor where the concepts of moral good and objective values may not hold universal meaning, leading to the need for a different kind of moral foundation, potentially found in reason as proposed by other philosophers like Plato, and later explored using diverse ethical frameworks, including Kant's categorical imperative and discussions around well-being and objective goods.
