Our contention is that all of the major arguments for abortion are also arguments for permitting infanticide. One cannot distinguish the fetus from the infant in terms of a morally significant intrinsic property, nor are they morally discernible in terms of standing in different relationships to others. The logic of our position is that if such arguments justify abortion, then they also justify infanticide. If we are right that infanticide is not justified, then such arguments will fail to justify abortion. (...) We respond to those philosophers who accept infanticide by putting forth a novel account of how the mindless can be wronged which serves to distinguish morally significant potential from morally irrelevant potential. This allows our account to avoid the standard objection that many entities possess a potential for personhood which we are intuitively under no obligation to further or protect. (shrink)

The potential for healthy development is the key to determining the moral status of mindless and minimally minded organisms. It even provides the basis for a defense of speciesism. Mindless and minimally minded human beings have interests in the healthy development of sophisticated mental capacities, which explains why they are greatly harmed when death, disease, and other events frustrate those interests. Since the healthy development of members of non-human species doesn’t produce the same sophisticated mental capacities, mindless and minimally minded (...) non-human beings lack the interests of mindless and minimally minded human beings. The absence of such interests in developing valuable mental capabilities means non-humans can’t be benefited and harmed to the same degree as human beings. This results in mindless and minimally minded non-humans having lower moral status than human beings. This doesn’t mean that any member of our species is more valuable than any other member of any other possible species. We instead claim that human beings with undeveloped or impaired minds have greater moral status than any member of any other known species that has manifested equivalent mental capacities. (shrink)

This paper presents an account of how human spontaneous embryonic chimeras are formed. On the prevalent view in the philosophical literature, it is said that chimeras are the product of two embryos that fuse to form a new third embryo. We call this version of fusion synthesis. In contrast to synthesis, we present an alternative mechanism for chimera formation called incorporation, wherein one embryo incorporates the cells of a second embryo into its body. We argue that the incorporation thesis explains (...) other types of chimera formation, which are better understood, and is more consistent than synthesis with what is known about embryological development. Incorporation also has different implications than synthesis and so avoids the philosophical puzzles that are often said to accompany embryonic chimera formation—puzzles which pose problems to the human embryo’s persistence from fertilization to the fetal stage of human development.

A number of philosophers maintain that the destruction of an embryo in the first 2 weeks after fertilization is not morally problematic as it is metaphysically impossible for any human organism to then have existed. We contend that the typical adult human organism was once a zygote so there is no metaphysical shortcut to justify early abortion. We show that five arguments against human organisms ever having been zygotes fail. All of the arguments have to do with one variant or (...) another of the zygote or early embryo dividing. They do not provide any reason to believe that since some adult organisms are not identical to zygotes due to earlier divisions, none could have been. (shrink)

Is it coherent to be personally opposed to abortion but to accept others’ decisions to terminate their pregnancy? This might appear to be the case if one appeals to the different situations and attitudes of pregnant women. To the contrary, only those people whose personal opposition to abortion is restricted to situations in which the pregnancy and its consequences are not very burdensome can consistently hold their IPOB position and espouse an objective ethics. The vast majority of people claiming to (...) be merely personally opposed cannot coherently sustain that position. To be logically coherent, the latter not only must be committed to condemning the abortions of others and have the moral standing to do so, but more importantly and controversially, must be committed to call for a legal ban on abortion rather than restrict themselves to being merely personally opposed to abortion.

One often hears Catholic and non-Catholic politicians and private citizens claim “I am personally opposed to abortion... ” but add that it is morally permissible for others to accept abortion. We consider a Rawlsian defense of this position based on the recognition that one’s opposition to abortion stems from acomprehensive doctrine which is incompatible with Public Reason. We examine a second defense of this position based upon respecting the autonomy of others and a third grounded in the harm to the (...) unwilling mother overriding that to the aborted fetus. We look at a fourth and fifth defense based upon our epistemic ignorance regarding the burdens on others of unwanted pregnancies and the ontological and moral status of embryo. We find most versions of these defenses to be wanting and conclude that only if the proponents of the position are subjectivist about morals, which few are, can they offer a coherent defense. (shrink)
