I think that all of those are important. Obviously I do.

But I think that truth has a value of its own. Scientific truth has a value separate from whether it helps anyone or not.

The pursuit of scientific truth should of course not harm anyone (and I include animals and the environment in that "anyone"), but as someone who loves science and loves learning more about how the world and universe works, I can't agree that all science should be judged on whether it improves the world beyond expanding our knowledge.
