Is there a logical slippery slope from voluntary to nonvoluntary euthanasia?

Area of Science:

• Bioethics
• Medical Ethics
• Philosophy of Medicine

Background:

• John Keown presented a slippery slope argument linking voluntary euthanasia (VAE) to nonvoluntary euthanasia (NVAE).
• Hallvard Lillehammer critiqued Keown's argument, identifying a potential fallacy.
• The ethical permissibility of VAE and NVAE remains a significant debate in medical ethics.

Purpose of the Study:

• To analyze and restate Keown's slippery slope argument to address Lillehammer's critique.
• To determine the logical consistency between VAE and NVAE based on established medical decision-making principles.
• To evaluate the ethical implications for VAE if NVAE is deemed unacceptable.

Main Methods:

• Logical analysis of ethical arguments concerning euthanasia.
• Application of general principles of medical decision-making to euthanasia scenarios.
• Reconstruction of the slippery slope argument to circumvent identified fallacies.

Main Results:

• The slippery slope argument from VAE to NVAE can be restated to avoid the identified fallacy.
• If VAE is ethically justifiable, implying death can be of overall benefit, then NVAE should logically follow.
• Medical decision-making principles support the interconnectedness of VAE and NVAE justifications.

Conclusions:

• VAE and NVAE should be accepted concurrently based on logical and ethical consistency.
• If NVAE is considered ethically unacceptable, then VAE must also be rejected.
• The justification for VAE necessitates a re-evaluation of the stance on NVAE.
