On this cloudy winter's day I have been meditating on a short argument recently presented by Sam Harris on his Facebook page. This popular thinker has, for some time, been attempting to reduce ethics to science, and he has recently put forward an argument which he believes succeeds in doing so. As someone who knows very little, I find myself drawn to people who make big knowledge claims. I am, as you know, especially interested in Ethics, so I eagerly read Harris's argument.
Harris wants to show that ethics and values can be derived from facts about the world. If he succeeds in doing this, he will solve the famous is-ought problem. The is-ought problem suggests that no amount of knowledge about how the world happens to be can lead us to conclusions about how the world ought to be and how we ought to behave. Decisions about how we should behave may be informed by empirical facts, but ultimately they are based on values which do not seem to be derivable, in themselves, from empirical facts.
