Abstract

In a well known story Derek Parfit describes a disconnection between two entities that normally (in real life) travel together through space and time, namely your personal identity consisting of both mind and body. Realising the possibility of separation, even if it might never happen in real life, new questions arise that cast doubt on old solutions. In human reproduction, in real life, at present the fetus spends approximately nine months inside the pregnant woman. But, we might envisage other possibilities. Historically, the first era is the normal conception inside the woman, the growth of the fetus in the womb and then, after nine months, birth and the appearance of a new individual. The second era is In Vitro Fertilisation (IVF). The fetus starts outside the woman as a fertilised egg, moves to the body of the woman and spends nine month there, where the body of the woman and the fetus travel together in space-time to separate at birth. In the third era of reproductive ectogenesis, the two never travel together. The fetus spends its gestational time entirely outside the woman’s body. We have two entities separated in space-time the whole time. The intimate connection consisting in the fetus being a part of the woman’s body is gone.
