"Science is a quest for understanding. A search for truth seems to me to be full of pitfalls. We all have different understandings of what truth is, and we'll each believe, or we are in danger of each believing, that our truth is the one and only absolute truth, which is why I say it's full of pitfalls. I think a search for understanding is much more serviceable to humankind, and is a sufficiently ambitious goal of itself."
