Resumen:
For transhumanism, humanity is a stage which, guided by biological evolution, was preceded by other earlier stages and which will be followed by others that are newer. According to transhumanism, we must break the inertia of blind causes that govern evolution and, through biotechnology, attain what is called a ¿better life¿. Those authors who are supportive of this current of thought develop their proposals by negating the existence of a human nature, but without abandoning the conviction that it will be possible to define what a ¿better life¿ consists in. In this article we will analyze the clarity and rigor with which transhumanists present the ultimate goal of their proposal, the relation between the end and the means proposed for attaining it, and, finally, we will bring to light certain inconsistencies that result from their rejection of the position that human nature could have a normative value.
