The Concept of Anxiety
All of Kierkegaard's books have either a preface, dedication, or prayer at the beginning. This book includes a lengthy introduction. "The Concept of Anxiety" was published on exactly the same date as "Prefaces", June 17, 1844. Both books deal with Hegel’s idea of mediation. Mediation is a common thread throughout Kierkegaard’s works. His work up to this point was to show that faith was being mediated by knowledge. Here he takes up the questions of sin and guilt.
Viruses of the Mind
"Viruses of the Mind" is an essay by British evolutionary biologist Richard Dawkins, first published in the book "Dennett and His Critics: Demystifying Mind" (1993). Dawkins originally wrote the essay in 1991 and delivered it as a Voltaire Lecture on 6 November 1992 at the Conway Hall Humanist Centre. The essay discusses how religion can be viewed as a meme, an idea previously expressed by Dawkins in "The Selfish Gene" (1976). Dawkins analyzes the propagation of religious ideas and behaviors as a memetic virus, analogous to how biological and computer viruses spread. The essay was later published in "A Devil's Chaplain" (2003) and its ideas are further explored in the television programme, "The Root of All Evil?" (2006).
