Uranus in Pisces gives humanistic and socially directed ideas. Religious and spiritually oriented trends gain great importance. Many discoveries appear in the Neptunian areas. New areas of knowledge, controlled by Neptune, appear. The influence of Neptune is also well traced in the form of expression of thoughts. Insights of these periods often take the form of art, for example, science fiction.
Philosophical ideas of Uranus in Pisces are expressed so creatively that when you try to transfer them into the language of logic, their essence eludes. When it comes to philosophical currents born of Uranus in Pisces, it is not easy even to determine their time frame and clearly identify the criteria for classification of thinkers. The typical example of it is existentialism. Pisces are already observed in the contradictions of the term “existence”, which by definition refers to something alive and unique, which is difficult to generalize and conceptualize in terms of formal logic.
The origin of existentialism is associated with the name of the Danish philosopher and theologian Soren Kierkegaard, who’s first works were issued during the transit of 1835-1843. At the next transit of Uranus through Pisces at 1919-1927, existentialism flourished. This period is associated with Karl Jasper, who was among the first to raise the existential problems of the twentieth century (Psychology of Worldviews, 1919), and Martin Heidegger (Being and Time, 1927). In those years the first French existentialist philosopher Gabriel Marcel writes The Metaphysical Diary (1927) and a number of plays (1920’s).
