We now face risks we can’t easily analyze

Our existence is invaded by science and technology as never before. For many of us, this brings comfort and rewards, but this existence is also more complicated and sometimes agitated.

Our lives are full of real and imaginary risks, and distinguishing between them isn’t easy. We have to be able to decide what to believe and how to act on that.
