One needs to be intelligent, brave and a very good person with just the right balance between arrogance and humility to be a true atheist (or a good scientist). There is so much to be gained from reading this fascinating book which (among other points) explodes the Bible as history, and details the use of the existence of God, both in the past and present as a dangerous tool of megalomania.
Although I cling to my agnosticism like a security blanket, I cannot help but agree with the humanistic ideas and the plea for the eradication of ignorance Mr.Dawkins sets out, as a condition for the further survival and evolution of the human race.
