That post was partially triggered by the bombardment of intellectually dishonest or outright false pro-abortion campaign ads I’ve had to endure lately from Maryland and Virginia Democratic candidates. (Did you know that the Republicans will enact a national abortion ban?) In one, a GOP candidate is mocked for saying that the Dobbs decision overturning Roe was legally correct. “Huh?” says a woman or actress whom I guarantee didn’t read the opinion (or Roe) and who couldn’t explain the legal arguments if a gun was pointed at her head. Almost all legal scholars and lawyer admit that Roe v. Wade was incompetent; their major argument for not reversing it is “It’s too late: stare decisus!” Let’s ask that “Huh” lady to define stare decisus.
As he/she/it often does, one of Extradimensional Cephalopod‘s posts, this time an argument for abortion, prompted a sterling response. Here is Ryan Harkins’ Comment of the Day on the post, “Is This the Level of Critical Thinking Devoted To Pro-Abortion Advocacy?”.….

The topic of “nature” is an important one to discuss, because ethics follows nature. Classically, we can ask what something is, and what about that thing makes it what it is. The whole notion of taxonomy relies on defining “what” something is. When we examine things, we notice two main categories of details. One category is essentials, and the other category is accidentals. It is essential to the nature of water to be composed of two hydrogen atoms and one oxygen atom, and it is essential to the nature of water to be a solid at some temperature, a liquid at another temperature, and a gas at a third temperature. It is accidental to water to be wet, because ice and super-heated steam are not wet, and it is an accident of water to be white, because snow is white but steam is transparent. Another way to put that is water can lose wetness and still be water, but if water loses its hydrogen atoms, it is no longer water.
There is such a thing as human nature. We can discuss and reason and argue about what details of human existence are essential and which are accidental, but I think we can agree that at some point if enough details are removed, what remains is no longer human. If we take the evolution of species (which Catholics are allowed to believe in), while we notice a gradation of speciation, we nevertheless notice that distinct species have disparate traits that are essential to being that species. Certainly it seems that a very distinct and essential detail of being human is being a rational creature. What Sarah B. brought up about rational kinds notices that a rational nature, while necessary, is not sufficient to identify as human, as there could be rational alien races in the universe, and the Catholic belief in purely spiritual beings that we call angels and demons postulates rational natures that are not human. In a similar way, there are shared details among primates, but there are different details about humans that distinguish them from other primates.
