Critiquing Marquis's Argument on Abortion: An Analytical Perspective

In this essay, I will critically evaluate the argument presented by Don Marquis regarding abortion. Marquis's famous pro-life argument hinges on the claim that abortion is morally wrong primarily because it deprives a fetus of a valuable future, similar to the future of a normal adult human. My task is to summarize Marquis’s general argument, analyze the supporting premises, and then present a substantial objection to his reasoning.

Summary of Marquis’s Argument

Marquis’s central conclusion is that abortion is generally, and in most cases, morally impermissible because it deprives a fetus of a future valuable besides its current existence. His argument is rooted in proponent of the "future-like-ours" (FLO) theory, which posits that what makes killing wrong is the fact that it deprives the victim of their future. Marquis argues that just as killing a normal adult or child is wrong because it deprives them of their ongoing valuable future, similarly, abortion is wrong because it denies the fetus its potential future full of experiences, pleasures, and projects.

The premises supporting this conclusion are as follows: First, it is generally wrong to kill an adult human because it deprives them of a valuable future. Second, a fetus, being a human biological organism, has the potential to develop into a being with a future similar to ours. Third, therefore, abortion is morally wrong because it deprives the fetus of its FLO, a future with similarity to ours, which has intrinsic value. Marquis further suggests that this duty to protect future valuable experiences is what underpins the moral prohibition against killing, extending this moral consideration to fetuses.

Marquis’s argument is consistent with deontological ethical theories that emphasize the inherent value of potential futures. It especially aligns with Kantian ideas that emphasize respect for rational beings; however, Marquis shifts the emphasis from rationality to the value of one’s future potential, thus supporting a broader moral consideration.

In defending his FLO theory, Marquis considers objections such as cases where killing is justified, e.g., self-defense, and responds by differentiating these from abortion, which generally involves the wrongful killing of a being with a valuable future. Marquis also acknowledges that his argument primarily concerns "ordinary" cases of abortion and that there are exceptions in cases of rape or threats to the mother’s life.

Objection to Marquis’s Argument

One of the most significant objections to Marquis’s FLO theory pertains to its application to cases of embryonic or fetal development stages, particularly early-stage abortions. The objection is that Marquis’s premise that a fetus has a future like ours, thus making abortion morally wrong, may be overgeneralized, especially during the earliest stages of development when the fetus lacks consciousness, sentience, or the capacity for experiences comparable to those of a person with a valuable future.

This objection focuses on the premise that a fetus at very early stages of development possesses the same moral status as a mature human being with a future worth protecting. Critics argue that this premise overlooks biological and psychological facts about fetal development, such as the absence of consciousness, sentience, and the capacity to value or experience a future. Without these qualities, the fetus’s future, as conceived by Marquis, lacks the intrinsic value that underpins his moral argument.

Philosophers supporting this objection often draw on debates surrounding moral status, emphasizing that moral consideration should be proportional to the capacities for consciousness and subjective experience. For instance, David Boonin argues that moral rights are linked to cognitive functions, such as consciousness and perception, which are absent in early fetuses (Boonin, 2003). Accordingly, denying the fetus the same moral status as a person with a rich, valuable future may be justified until it develops certain capacities.

This line of reasoning is reinforced by ethical principles like the capacity for suffering and experiential awareness, which many ethicists regard as essential for moral consideration. Examples include the distinction made in animal ethics between sentient animals and organisms lacking consciousness, where the latter are given less moral weight because of their limited capacity for subjective experience (Regan, 2004). Applying a similar logic, the fetus’s moral status increases with its development and capacity for consciousness, challenging Marquis’s claim that all stages of fetus development are equally deserving of protection due to their potential future.

Therefore, this objection suggests that Marquis’s FLO theory does not necessarily entail a blanket moral prohibition on all abortion cases, particularly at early stages where the fetus lacks the relevant capacities to possess or appreciate a valuable future.

Conclusion

In conclusion, Marquis's argument provides a compelling framework linking the morality of killing to the deprivation of potential future experiences. While his theory robustly supports the moral wrongness of abortion in many cases, it faces substantive challenges—most notably, the question of moral status during early fetal stages. Recognizing that potential future value depends significantly on fetal capacities for consciousness and subjective experience, this objection underscores the importance of developmental considerations when applying FLO theory. A nuanced approach may reconcile Marquis’s insights with the biological facts of fetal development, leading to a more differentiated moral stance on abortion.
