There may be ultimate answers, but if there are, I would be sorry if we were to find them. For my own sake I would like very much to find them, but their discovery would leave nothing for those coming after me to seek. Each generation builds on the advances of the previous generation, and this is as it should be. As human beings, we need the quest.
I can live with doubt, and uncertainty, and not knowing. I think it’s much more interesting to live not knowing than to have answers which might be wrong. I have approximate answers, and possible beliefs, and different degrees of certainty about different things, but I’m not absolutely sure of anything. There are many things I don’t know anything about, such as whether it means anything to ask “Why are we here?” I might think about it a little bit, and if I can’t figure it out then I go on to something else. But I don’t have to know an answer. I don’t feel frightened by not knowing things, by being lost in the mysterious universe without having any purpose.
