Who is David Hume from The Blind Watchmaker and what is their importance?

David Hume was a Scottish philosopher who, one hundred years before Darwin, questioned the use of the complexity in design in nature for proving the existence of a God. He was not able, however, to propose an alternative explanation of biological design. Darwin enrolled in Hume's university of Edinburgh forty years after Hume's death and subsequently provided the world with the means to be an intellectually satisfied atheist.
