|What lies at the heart of every living thing is not a fire, not warm breath, not a spark of life. It is information, words, instructions. If you want a metaphor, don’t think of tires and sparks and breath. Think, instead, of a billion discrete, digital characters carved in tablets of crystal. If you want to understand life, don’t think about vibrant, throbbing gels and oozes, think about information technology.
– Richard Dawkins (1941 -)
