To every individual’s constitutionally-guaranteed freedom to procreate there corresponds, in neganthropic terms, the impossibility of any individual’s adopting, beforehand, any position with regard to the beginning of his or her own existence – that is to say, an aspect of unfreedom.
Let us consider Article 2 of the Basic Law of the Federal Republic of Germany, paragraphs (1) and (2):
“(1) Every person shall have the right to free development of his personality insofar as he does not violate the rights of others or offend against the constitutional order or the moral law.
(2) Every person shall have the right to life and physical integrity. Freedom of the person shall be inviolable. These rights may be interfered with only pursuant to a law.”
From paragraph (1)’s guaranteeing of the right to the free development of personality one may derive a right to freedom of procreation. At the same time, according to paragraph (2), each citizen has the right to physical integrity. This, however, would require the existence of a duty to give birth to a healthy child: a duty which is almost never spoken about. But this in turn means: nobody has the right to be born healthy. – The disadvantage of having to accept being born unhealthy counts as an acceptable price to pay for avoiding the infringement of the freedom of procreation.
