Additional Information: This quote by author and neuroscientist Sam Harris means that we, as a society, need to agree on the answers to moral questions in the same way that we must agree on the answers to important scientific questions, such as how diseases spread or how to build safe buildings. The quote is from Harris' 2010 TED Talk about how science should be the basis on which we shape our moral values, just as we rely on science to provide other important guidance in life.
