Abstract

The human brain is in great part what it is because of the functional and structural properties of the 100 billion interconnected neurons that form it. These make it the body’s most complex organ, and the one we most associate with concepts of selfhood and identity. The assumption held by many supporters of human enhancement, transhumanism, and technological posthumanity seems to be that the human brain can be continuously improved, as if it were another one of our machines. In this paper, I focus on some of the ethical issues that we should keep in mind when thinking about memory enhancement interventions. I start with an overview of one of the most precious capacities of the brain, namely memory. Then I analyze the different kinds of memory interventions that exist or are under research. Finally, I point out the issues that we should not forget when we consider enhancing our memories. In this regard, my argument is not against memory enhancement interventions; rather, it concentrates on the need to “keep in mind” what kind of enhancements we want. We should consider whether we want the kind of “enhancements” that will end up making us lose synapse connections, or the kind that promote more use of them.
