Some critics doubt the antinatalists‘ humanist vision. Many of those critics envision mankind’s future under the sign of hope. To have given up hope, in the eyes of the critics, is a moral blemish. Saying this, however, the critics are disregarding that – under the sign of hope –they are prepared to experimenting on human beings. They are prepared to experimenting on human beings inasmuch as they are in favour of propagation with uncertain outcomes. Experimenting on human beings would not deserve to be called humanist.
