Permitting gene editing for enhancement is an extension of reproductive freedom, allowing prospective parents to exercise autonomy in making choices that aim to give their children the best possible start in life and maximize their well-being.
✗
Objection:
Reproductive freedom concerns the decision to procreate, not the right to permanently alter the inheritable genetic makeup of a future person who cannot consent, fundamentally changing the nature of the claimed parental right.
✓
Response:
Standard procreation inherently involves determining the permanent, inheritable genetic makeup of a non-consenting future person, meaning the criteria used to exclude genetic alteration from reproductive freedom apply equally to all natural births.
✗
Objection:
Focusing solely on parental intent ignores the immense, irreversible ethical hazards and substantial safety risks inherent in imposing untested, permanent genetic changes on a non-consenting individual.
✓
The ethical distinction between therapeutic gene editing (treating disease) and enhancement (improving function) is arbitrary, as many enhancements represent a continuum of health optimization and proactive disease prevention.
✗
Objection:
Establishing an ethical line on a continuous therapeutic spectrum is not inherently arbitrary; non-arbitrary thresholds are necessary for regulation and clinical decision-making based on risk evaluation and societal values.
✓
Response:
The necessity of establishing a regulatory threshold only proves that a line must exist, but it does not ensure that the precise location chosen on a continuous spectrum is anything other than an arbitrary selection.
✓
Response:
Basing the threshold on inherently variable and subjective "societal values" means the resulting ethical line reflects contingent preferences or political compromise rather than an objective, non-arbitrary standard.
✗
Objection:
The distinction is substantive because enhancements like radical cognitive augmentation or new sensory organs represent a qualitative leap entirely unrelated to treating disease or health optimization. These enhancements aim to create entirely new human capabilities, not merely restore function or prevent illness.
✓
Gene editing for enhancement provides a unique means to mitigate the disadvantages imposed by the genetic "natural lottery," offering a pathway toward greater equality of opportunity and compensating for genetic misfortune.
✗
Objection:
Existing social and medical accommodations, such as universal healthcare or targeted educational support, already function to mitigate disadvantages arising from the natural lottery, so gene editing is not a unique means.
✓
Response:
Gene editing is a unique mechanism because it addresses the biological cause of a disadvantage at the source, potentially preventing manifestation, whereas existing accommodations only mitigate the resulting effects or symptoms after they occur.
✗
Objection:
If access to expensive genetic enhancement is determined by wealth or social class, the technology will exacerbate existing socioeconomic inequalities rather than promote greater equality of opportunity.
✗
Objection:
Reliable germline editing for enhancement is currently biologically impossible because current technologies, like CRISPR, cannot safely eliminate unpredictable off-target mutations or guarantee long-term stability.
✓
Allowing human enhancement could yield substantial societal benefits by increasing human cognitive and physical capabilities, thereby accelerating innovation, economic growth, and the ability to solve complex global challenges.
✗
Objection:
Increased individual capabilities will not automatically translate to societal benefits if accessibility is unequal, potentially exacerbating existing social and economic polarization and increasing conflict rather than accelerating innovation.
✓
Response:
Increased polarization and conflict are not inevitable consequences of unequal technological access, as large disparities can also lead to stable hierarchies or non-confrontational stratification rather than an active escalation of societal conflict.
✓
Response:
Accelerated innovation and exacerbated social polarization are not mutually exclusive outcomes, as technological advancement often creates massive, centralized wealth that simultaneously increases inequality and drives further progress.
✗
Objection:
Solving complex global challenges is primarily constrained by systemic political, economic, and institutional barriers, making increased individual human capacity largely irrelevant to overcoming these systemic obstacles.
✓
Response:
Systemic problems are constituted by the aggregated decisions of individuals within institutions, meaning increased individual capacity for critical thinking and ethical governance is prerequisite for effectively challenging or restructuring those systems.
✓
Response:
Overcoming systemic constraints does not render individual capacity irrelevant but rather heightens the demand for highly specialized capabilities—such as expertise in policy, organizational design, and technological innovation—to create the necessary systemic changes.
