Ever since the philosophers David Hume and G. E. Moore identified the "Is-Ought problem" between descriptive statements (the way something "is") and prescriptive statements (the way something "ought to be"), most scientists have conceded the high ground of determining human values, morals, and ethics to philosophers, agreeing that science can only describe the way things are but never tell us how they ought to be. This is a mistake.
We should be worried that scientists have given up the search for determining right and wrong and which values lead to human flourishing just as the research tools for doing so are coming online through such fields as evolutionary ethics, experimental ethics, neuroethics, and related fields. The Is-Ought problem (sometimes rendered as the "naturalistic fallacy") is itself a fallacy. Morals and values must be based on the way things are in order to establish the best conditions for human flourishing. Before we abandon the ship just as it leaves port, let’s give science a chance to steer a course toward a destination where scientists at least have a voice in the conversation on how best we should live.
