This book presents the different modalities of technoscientific transhumanism. Their arguments are discussed, seeking to elucidate their strengths and weaknesses.

Transhumanism is one of the philosophical and cultural movements that have attracted more attention in recent years. It advocates the free use of technology for the improvement of the human being, both in his physical capacities, as well as in the mental, emotional and moral, transcending all its current limits. The technologies at hand are genetic engineering and the development of intelligent machines. According to the proponents of transhumanism, with the help of these technologies we can end the suffering, with the biological limitations that produce it, and we can even overcome aging and death.

Although many transhumanists do not see it desirable to bring these improvements to a point where the improved individual no longer belongs to the human species, others, designated as posthumanists, consider that this is precisely the ultimate goal: the creation of one or more new species From ours.

The promises made by the advocates of transhumanism are very ambitious, and not all are justified. But on the other hand, the criticism that modifying human nature endangers the bases of moral life, dignity and human rights, contains arguable philosophical assumptions and their consequences are excessively radical. There are other approaches that allow for a more balanced evaluation, on which a greater social agreement could be built in the future.
