The human mind is always an unfinished project, says British journalist Caspar Henderson. An abstract entity susceptible to changes that are activated by the work and grace of our master organ: the brain, something more than a piece of meat wrapped in the shell of the skull. Because since the beginning of time, our brain has been evolving along with the instruments that he Homo sapiens has been inventing. Therefore, the Homo sapiens is due to homo faber and vice versa.
