Ethics questioned by the alien}, AUTHOR={Jacques Arnould, }, JOURNAL={Art and Science}, VOLUME={6}, NUMBER={Special issue}, YEAR={2022}, URL={http://www.openscience.fr/Who-goes-there-Ethics-questioned-by-the-alien}, DOI={10.21494/ISTE.OP.2022.0799}, ISSN={2515-8767}, ABSTRACT={Ethics is not usually questioned by the imagination. However, the hypothesis of a life, or even an extraterrestrial intelligence cannot be ignored by ethics. In this case, it is not so much a question of questioning ourselves about the mores of possible extraterrestrials, but rather of taking an interest in the human being, when confronted with a possible life that he cannot share.}}
