The Unthinkable Conclusion: Derek Parfit's Budding Antinatalism
1Aalto University School of Business, PO Box 21210, FI-00076Aalto, Finland.
Summary
Causing a person to exist with a life barely worth living may be wrong, according to the nonidentity problem. This philosophical analysis suggests that if such lives are inevitable, having children could be considered morally wrong, impacting reproduction ethics.
Area of Science:
- Philosophy of Ethics
- Population Ethics
- Reproductive Ethics
Background:
- Derek Parfit's nonidentity problem posits that actions affecting future persons may not be wrong for those persons, even if their existence results in a life barely worth living.
- Parfit also argued that agents can be necessary conditions for the existence of future persons.
Purpose of the Study:
- To explore the implications of combining Parfit's views on the nonidentity problem with the concept of bringing individuals into existence with lives not worth living.
- To analyze whether Parfit's own framework could lead to an antinatalist conclusion regarding procreation.
Main Methods:
- Philosophical analysis of Derek Parfit's ethical theories on the nonidentity problem and population ethics.
- Application of these theories to hypothetical scenarios involving the creation of individuals with lives of questionable value.
Main Results:
- The study suggests that if every family line is destined to produce an individual with a life not worth living, and if the benefits to others cannot justify this, then having children could be deemed wrong.
- Parfit's ethical framework, when extended, could logically support an antinatalist stance, though he did not explicitly draw this conclusion.
Conclusions:
- Parfit's nonidentity problem, when applied to the creation of individuals with lives barely worth living, opens the door to a potential antinatalist conclusion.
- The antinatalist position, derived from Parfit's ethics, warrants consideration within discussions on population ethics and the future of reproduction.

01:38Fertilization
During fertilization, an egg and sperm cell fuse to create a new diploid structure. In humans, the process occurs once the egg has been released from the ovary, and travels into the fallopian tubes. The process requires several key steps: 1) sperm present in the genital tract must locate the egg; 2) once there, sperm need to release enzymes to help them burrow through the protective zona pellucida of the egg; and 3) the membranes of a single sperm cell and egg must fuse, with the sperm...
01:17Understanding Species and Reproductive Barriers
A species is a group of organisms that interbreed and produce fertile offspring. Typically, individuals of the same species appear similar and share common characteristics due to their highly similar genomes. However, not all organisms that look alike are members of the same species. Various mechanisms keep most species discrete. While some mechanisms prevent reproductive behavior and fertilization (pre-zygotic isolation), others prevent the production of fertile offspring after mating has...
02:08Gene Conversion
Other than maintaining genome stability via DNA repair, homologous recombination plays an important role in diversifying the genome. In fact, the recombination of sequences forms the molecular basis of genomic evolution. Random and non-random permutations of genomic sequences create a library of new amalgamated sequences. These newly formed genomes can determine the fitness and survival of cells. In bacteria, homologous and non-homologous types of recombination lead to the evolution of new...
03:09Meiosis I
Meiosis is the division of a diploid cell into haploid cells forming sperm and eggs in animals through differentiation. Meiosis I is the first stage of meiosis, where the genetic recombination of homologous chromosomes and the reduction of the ploidy level by half occurs.
Prophase I is the most extended and complex step of meiosis I characterized by synapsis, chromosome pairing, and recombination of the homologous chromosomes. This process is facilitated by a proteinaceous structure called the...

01:09Epistasis Analysis
Although Mendel chose seven unrelated traits in peas to study gene segregation, most traits involve multiple gene interactions that create a spectrum of phenotypes. When the interaction of various genes or alleles at different locations influences a phenotype, this is called epistasis. Epistasis often involves one gene masking or interfering with the expression of another (antagonistic epistasis). Epistasis often occurs when different genes are part of the same biochemical pathway. The...
01:23Criticisms of the Evolutionary Perspective
In a study where individuals posing as strangers offered compliments and proposed casual sex to students, the responses differed significantly based on gender. Not a single woman accepted the proposal, while 70% of the men agreed. This outcome provides a useful scenario to explore through the lens of evolutionary psychology and social learning theory, highlighting the diverse perspectives on human sexual behaviors.
