“Science and technology are what we can do; morality is what we agree we should or should not do.”
“Science doesn't tell us what we should do. It only tells us what is.”
“We should never wait for science to give us permission to do the uncommon; if we do, then we are turning science into another religion.”
“Freedom is not doing what we want, but what we should.”
“Then why do you want to know?""Because learning does not consist only of knowing what we must or we can do, but also of knowing what we could do and perhaps should not do.”
“Some days, doing "the best we can" may still fall short of what we would like to be able to do, but life isn't perfect on any front-and doing what we can with what we have is the most we should expect of ourselves or anyone else.”
