Root Metaphor and Bioethics.

Area of Science:

• Bioethics
• Philosophy of Science
• Metaphor Studies

Background:

• Existing research extensively covers metaphors in bioethics (e.g., body as property).
• This essay uniquely examines metaphors at the core of bioethics theories themselves.
• Stephen Pepper's (1942) concept of "root metaphors" (similarity, machine, organism, act) provides a theoretical framework.

Purpose of the Study:

• To analyze how major bioethics theories are grounded in specific root metaphors.
• To demonstrate that differing root metaphors represent fundamentally different worldviews.
• To argue that disputes between bioethics theories are irresolvable through rational discourse due to underlying worldview conflicts.

Main Methods:

• Conceptual analysis of prominent bioethics theories (principlism, rule-based ethics, casuistry, phenomenological ethics).
• Application of Stephen Pepper's "root metaphor" theory to these bioethics frameworks.
• Philosophical argumentation on the nature of theoretical disagreement.

Main Results:

• Principlism, rule-based ethics, casuistry, and phenomenological ethics are each grounded in distinct root metaphors.
• These root metaphors shape fundamentally different understandings of how the world operates.
• Arguments over the superiority of bioethics theories reflect clashes of these underlying worldviews.

Conclusions:

• Disagreements in bioethics are often rooted in incommensurable worldviews, expressed through distinct root metaphors.
• Accepting an alternative bioethics theory necessitates adopting a new fundamental metaphor for understanding reality.
• Rational discourse alone cannot resolve disputes between theories grounded in different root metaphors.
