A recent study explores a long-standing debate in philosophy about the concept of a "pure ego" in phenomenology, a branch of philosophy that studies conscious experience. The debate began with two influential thinkers, Paul Natorp and Edmund Husserl, who had differing methods that stemmed from their predecessors. The study aims to show how this initial debate laid the groundwork for a second debate within the phenomenological tradition, led by philosopher Aron Gurwitsch, who questions the idea of a "pure ego" as an element present in pure consciousness, a concept developed by Husserl, influenced by Natorp's ideas.
