Once a photograph of the Earth, taken from outside, is available, once the sheer isolation of the Earth becomes known, a new idea as powerful as any in history will be let loose.

It is in the world of ideas and in the relation of his brain to the universe itself that the superiority of Man lies. The rise of Man may justly be described as an adventure in ideas.

Well, we now have such a photograph... Has any new idea been let loose? It certainly has. You will have noticed how suddenly everybody has become seriously concerned to protect the natural environment... It seems to me more than a coincidence that this awareness should have happened at exactly the moment man took his first step into space.

It is emphatically the case that life could not arise spontaneously in a primeval soup of any kind.... Furthermore, no geological evidence indicates an organic soup ever existed on this planet. We may therefore with fairness call this scenario the myth of the pre-biotic soup.

He who lives among dogs must learn to pant.

Some super-calculating intellect must have designed the properties of the carbon atom, otherwise the chance of my finding such an atom through the blind forces of nature would be utterly minuscule.

Life cannot have had a random beginning. ... The trouble is that there are about two thousand enzymes, and the chance of obtaining them all in a random trial is only one part in 10 to the 40,000 power, an outrageously small probability that could not be faced even if the whole universe consisted of organic soup.
