Final answer:
The key difference in Bernard Williams' variations on philosophical cases typically lies in his emphasis on subjective experience and moral psychology over rigid principles. This approach demonstrates the impact of employing different philosophical models on the analysis of moral dilemmas.
Step-by-step explanation:
The student's question appears to reference a discussion on variations in cases or perspectives presented by Bernard Williams. Williams is known for his contributions to philosophy, including moral philosophy. The key difference the student is asking about may be related to how Williams' variation of a case provides a new perspective or alters the moral implications of the scenario compared to the original case discussed.
For example, in evaluating philosophical arguments or moral dilemmas, Williams often challenged prevailing notions of ethical objectivity, introducing variations that emphasized the importance of subjective experience and the complexities of moral psychology. This approach might contrast with other thinkers who apply more rigid, principle-based frameworks to moral and ethical analysis, illustrating the consequential impact of different philosophical models.
Understanding the key difference between Williams and other philosophical cases requires a consideration of the underlying principles, the context within which they are applied, and the outcomes they generate when applied to specific moral dilemmas.
