Anxiety
The philosopher Søren Kierkegaard, in "The Concept of Anxiety" (1844), described anxiety or dread associated with the "dizziness of freedom" and suggested the possibility for positive resolution of anxiety through the self-conscious exercise of responsibility and choosing. In "Art and Artist" (1932), the psychologist Otto Rank wrote that the psychological trauma of birth was the pre-eminent human symbol of existential anxiety and encompasses the creative person's simultaneous fear of – and desire for – separation, individuation, and differentiation.
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).
