Abstract

Our article seeks to demonstrate that Husserl’s approach to intersubjectivity in his First Investigation of 1901/1913 was rigorous rather than rash. To do so, it applies a combination of intentionality and whole-part logic that has been overlooked in Husserl study. It therefore starts from Husserl’s Prolegomena of 1901 to follow his normative phenomenology until it excludes knowledge of another’s consciousness, then unpacks how he does so by his “proofs” in his 1913 Third Investigation, to apply those results to his First Investigation. The outcomes might demonstrate an unexpected rigour in Husserl’s early address to intersubjectivity, and even support a novel logic that considers alterity
