Browsing the Atheists of Silicon Valley science links this morning I came across an online edition of Richard Dawkins's 1986 publication The Blind Watchmaker. It it, Dawkins argues against teleology, i.e. the principle of directed design in nature, and explains how evolution can account for the apparent design that we observe in the world around us.
I've been meaning to read this book for sometime, so I was pleased to have come across it. From what I understand, this book would be an excellent read for those who find the claims of the Intelligent Design movement to have intuitive appeal.
