We can learn about ourselves. If we don't step up and begin to learn about the universe, we will never learn about our own courage, our own equality, our own ways of seeing the world. By striving to understand the universe that we inhabit, we are simultaneously striving to understand the people that we are. Discoveries--even when they have nothing to do with our daily lives--change the way that we see the universe. Philosophy hasn't died: it's become science.
