"You see, one thing is, 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 uncertainty about different things, but I am not
absolutely sure of anything and there are many things I don't know anything
about, such as whether it means anything to ask why we're here... I don't
have to know an answer. I don't feel frightened not knowing things, by being
lost in a mysterious universe without any purpose, which is the way it really
is as far as I can tell. It doesn't frighten me."
[Richard P. Feynman, "Genius, the life and science"]
