"But what if the vast majority of scientists all have faith in the one unverified idea? The modern 'standard' scientific version of the origin of life on earth is one such idea, and we would be wise to check its real merit with great care.
Has the cold blade of reason been applied with sufficient vigour in this case? Most scientists want to believe that life could have emerged spontaneously from the primeval waters, because it would confirm their belief in the explicability of Nature the belief that all could be explained in terms of particles and energy and forces if only we had the time and the necessary intellect.
They also want to believe because their arch opponents - religious fundamentalists such as creationists - do not believe in life's spontaneous origin.
It is this combative atmosphere which sometimes encourages scientists writing and speaking about the origin of life to become as dogmatic and bigoted as the creationist opponents they so despise."
