Science like a candle in the dark

Rereading one of my favorite books. The Demon-Haunted World by Carl Sagan. One of my favorite quotes speaks to our time still.
Avoidable human misery is more often caused by not so much by stupidity, but by ignorance, particularly ignorance about ourselves. I worry that…pseudoscience and superstition will seem year by year more tempting, the siren song of unreason more sonorous and attractive.
…The candle flame [of Science] gutters. It’s little pool of light trembles. Darkness gathers. The Demons begin to stir.
