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.
Anne Conway (philosopher)
The text itself was probably written in 1677 and shows the influence of Franciscus Mercurius van Helmont.
The text was first published in Latin translation by van Helmont in Amsterdam in 1690 as "Principia philosophiae antiquissimae et recentissimae". An English edition appeared in 1692. The "Principles" develops Conway's monistic view of the world as created from one substance. Conway is critical of the Cartesian idea that bodies are constituted of dead matter, of Henry More's concept of the soul in his "Antidote Against Atheism," and of dualist theories of the relationship between the body and spirit.
