I agree with the most is
” Nothing in life is to be feared, it is only to be understood. Now is the time to understand more, so that we may fear less.”
Because science can make us to knew lots of new things, something we didn’t know. We always fear that, but when we knew what it is , we won’t fear it anymore. For example, human didn’t know was fire long ago. So they feared that. But when they knew what it is, they were not fear it anymore, and learned how to use that.
