The way I think of it is that we are exploring, we are trying to find out as much as we can about the world.

Whatever way it comes out, nature is there and she’s going to come out the way she is.

Therefore, when we go to investigate it, we shouldn’t pre-decide what it is we’re trying to do except to find out more about it.

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 aproximate answers, and possible beliefs, and different degrees of certainty about different things, but I’m not absolutely sure of anything, and there are many things I don’t know anything about

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 which is the way it really is as far I could tell possible.

It doesn’t frighten me
