A “Kantian” Condemnation of Artificial Marital Birth Control

This post interrupts my critique of theory of the moral neutrality of sexual activity. But it is related to the critique of this theory by arguing that some sexual activity, viz., artificial marital birth control is immoral.

In a National Catholic Register article in the May 1, 2010 issue Fr. Matthew P. Schneider, LC, published an article “We Must Explain Why Contraception is Wrong.” Fr. Schneider made an important point for preserving our traditional Catholic moral teachings when they are being challenged from inside and outside the Church. A good way to start confronting these challenges is to offer a variety of arguments for critical evaluation and improvement during the next several months. I propose that we declare 2019 the year of Chastity during which amongst other things to strengthen our chastity we redevelop rational defenses of Catholic teaching on sexual morality. Fr. Schneider offered three arguments in his article. In this post, I sketch out another which can be called:

A “Kantian” condemnation of artificial marital birth control. It is one of many which should be considered along with being reformulated in the next few months.

This is not Kantian scholarship. I rely only on the overview type of knowledge of Kant one might acquire in a survey course in ethics.

Artificial marital birth control is use of physical or chemical techniques to prevent conception during or after coitus by a married couple.

The explicit, or implicit, maxim of a married couple who use artificial birth control can be expressed as follows:

We will perform the reproductive act which we are entitled by our community to perform but for a period of our choosing we shall prevent it from being a reproductive act.

Now consider the Kantian “Categorical Imperative” that we ought to act only on maxims which we can consistently will to be universal laws of nature.

Generalizing such a maxim as a universal law for humans could be expessed as follows:

People shall perform the reproductive act which they are entitled to perform by their community but for a period of their choosing shall prevent it from being a reproductive act.

Such a generalization is inconsistent because given basic demographic principles it leaves open the possibility of the reproductive acts becoming insufficient for reproduction in the sense of reproducing a population. Current demographic facts show that this possibility is being realized.

In appraising this argument, the first question should be an examination of the Kantian Categorical Imperative and then of technical points such as my use of the logical principle that a claim C is inconsistent if C implies possibly not-C.
