SPEAKERS

Richard Dawkins is a famous British evolutionary biologist, science populariser and author; a vocal critic of religion, and the most well-known atheist in the World.
Professor at the University of Oxford until 2008, currently an Emeritus Fellow of New College, Oxford. He is a theorist of biological evolution. He gained worldwide fame with his book The Selfish Gene (1976), which popularised the gene as the principal unit of selection in evolution and introduced the concept of the meme. His book The Extended Phenotype (1982) made an important contribution to evolutionary biology by showing that the phenotypic effects are not limited to an organism’s body, but can extend to the environment, including the bodies of other organisms. In 2006, he founded the Richard Dawkins Foundation for Reason and Science. Richard Dawkins is an outspoken opponent of creationism and the pseudoscientific concept of intelligent design, as well as of homeopathy, alternative medicine, dowsing, etc. For him, the logical consequence of understanding evolution is atheism. He is a well-known critic of religion. His most popular book, The God Delusion (2006), had an impact on changing the worldview of large numbers of people. In it, Dawkins argues that there is no reason to recognize the existence of a supernatural creator, and that religious beliefs are delusional and incompatible with science. In science, Dawkins sees not only a source of knowledge, but also aesthetic sensations, admiration for the beauty of nature (Unweaving the Rainbow and others). Several books by Richard Dawkins have been translated and published in Poland, including: The Selfish Gene, River Out of Eden, A Devil’s Chaplain, The God Delusion, The Greatest Show on Earth, The Magic of Reality, An Appetite for Wonder, A Brief Candle in the Dark, The Four Horsemen, Outgrowing God. Richard Dawkins has won numerous prestigious academic and writing awards and honorary doctorates. As a public intellectual, he regularly speaks in television and radio debates, predominantly on science and atheism.
