In the post-enlightenment Europe of the 19th century the highest authority was no longer the Church. Instead it was science. Thus was born racial anti-Semitism, based on two disciplines regarded as science in their day - the 'scientific study of race' and the Social Darwinism of Herbert Spencer and Ernst Haeckel.

Since Hiroshima and the Holocaust, science no longer holds its pristine place as the highest moral authority. Instead, that role is taken by human rights. It follows that any assault on Jewish life - on Jews or Judaism or the Jewish state - must be cast in the language of human rights.

Dreaming in public is an important part of our job description, as science writers, but there are bad dreams as well as good dreams. We're dreamers, you see, but we're also realists, of a sort.

I have a better internal and intuitive understanding of folklore and myth than science and technology, so in that way fantasy is easier.

The purpose of science is not to analyze or describe but to make useful models of the world. A model is useful if it allows us to get use out of it.
