The abortion issue is immensely complicated, and our position about it largely depends on how we answer several questions. One of those questions is, “when does life begin?” This sounds so simple to answer, but it couldn’t be more complicated. I’m a scientist, that’s what I do for a living. I have advanced training in these things, and I have no idea how to answer that question factually, and believe me I’ve tried. I’ve looked for evidence that I can use to help form my opinion about this part of the issue, and it’s one of the few areas where I honestly feel there is no scientific answer to the question. It’s simply not an empirical question.
