Volume 5 of Roman Ingarden's Collected Works assembles 13 relatively brief articles devoted by the renowned Polish philosopher (1893-1970) to Phenomenology as conceived of by his teacher Edmund Husserl. While some of these texts were in fact published during Ingarden's lifetime, a number of them have only been made known in Germany in a fragmentary form, if at all. These carefully wrought texts from various periods represent an instructive documentation of Ingarden's unabating engagement with Husserl's thinking over a number of decades.
