On April 16, 1618, the Jesuit scientists Adam Schall and Johann Schreck (a friend and colleague of Galileo) set sail from Lisbon, Portugal, bound for China1. In Schall’s possession was a book about the human body, and it championed the radical idea that the mind is created by the brain. This book, authored by the […]
Read More The Brain Scientists of the Qing DynastyScience is highly exclusive: the vast majority of people cannot participate in research, access research articles, influence what gets researched, or influence science-related policy-making. This exclusivity is worrisome, not only because it is unfair (and that unfairness is not evenly distributed across different groups of people), but also because it is a threat to science […]
Read More Elitism is a Threat to ScienceConsciousness is an ambiguous concept. It can mean a lot of different things, depending on the context. For example, I can say that I am conscious of something, as in, “I am conscious of the fact that I am currently writing about consciousness.” It can also mean self-consciousness or self-awareness: the notion that you know […]
Read More Measuring Consciousness in BitsA philosopher of science once told me, “Science is like a big, ornate building. Unless you’re an Einstein or a Newton, all you can do is etch away at a little flourish on the building’s facade – and then you die.” Though bleak, his thought did speak to a curious truth about the lives of […]
Read More Science is a Collective Human Endeavor – And That’s BeautifulI recently had a brief back-and-forth with Bobby Azarian about his new article on Raw Story. Azarian, a neuroscientist at George Mason University, argued that artificial intelligence (AI) could never be conscious. I highly recommend reading Azarian’s article: it’s a great distillation of some key concepts in the philosophy of mind, and he makes an […]
Read More Why Machines Could Be – But Aren’t – ConsciousBelow is the text of my newest article for the Berkeley Science Review: In October, 2004, the Dover Area School District in York County, Pennsylvania decided that intelligent design would be taught in their classrooms as an alternative to evolutionary theory. In response, a group of Dover parents sued the school district, claiming that […]
Read More Science versus Pseudoscience: The Demarcation ProblemThe threads that weave the cloth of our mentality are soulless. Our experience of the most beautiful sunset, our most fervent desires, our loftiest thoughts, and our most expansive feelings of love are storms of neural activity, nothing more. Science – and neuroscience in particular – has stripped our mental lives of a soul. But […]
Read More Love In A World Of AtomsScientists don’t yet know how life emerged on Earth. Darwin’s theory of evolution by natural selection explains how life evolved once it emerged, but it does not explain how life emerged in the first place. But science presses on. One of the main challenges in figuring out how life emerged from chemistry is defining what life is. […]
Read More Information and the Emergence of LifeGo back to Part 1. Go back to Part 2. From the discussion in the last two parts of this series on the ethics of cognitive enhancement, we can draw three conclusions. The first is that we should allow all forms of cognitive alterations that aren’t lethal and don’t lead you to harm others. As […]
Read More The Ethics of Cognitive Enhancement: Part 3Go back to Part 1. In Part 1 of this series on the ethics of cognitive enhancement, I pointed out that it is not logical to deny people access to new methods of cognitive enhancement as they become available, because such methods would not be categorically different from methods of cognitive enhancement that are currently legal and […]
