Below 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 The Demarcation Problem
The 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 Atoms

We may have evolved an instinct for war. Support for this idea comes from what anthropologist Richard Wrangham calls the Chimpanzee Violence Hypothesis. The […]Read More Why Humans Go To War
Scientists 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 Life
I recently had the pleasure of talking to Mark Baxter, Ph.D. about the status of neuroscience as a field. Mark is a neuroscientist who studies the molecular mechanisms of learning and memory. This is my second conversation with Mark. Several months ago, we discussed a controversial paper on the effects of marijuana consumption on the […]Read More Is Neuroscience a Mature Science?
Go 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 3
