Janoušek, H. Intentionality and Apriority. Study on the Relationship of Brentano’s and Husserl's Thought. Prague: Togga. 2015.
The book "Intentionality and Apriority" presents the basic concepts of Brentano's descriptive, a priori oriented psychology, with the emphasis on that part of Brentano's doctrine, which was developed by the phenomenology of Edmund Husserl, while some of the Aristotelian foundations of Brentano's project are also analysed. The contribution of Twardowski’s doctrine of the content and the subject matter of ideas is also discussed. The second part presents a brief outline of the development of Husserl's early concept of intentionality and the idea of its a priori description in the period before the publication of Logical Explorations, namely the distinction of representation and opinion, content and object, transformation of Husserl's concept of the judgement, acceptance of Bolzano's ideas and sentences in themselves, and Husserl's attempt to solve the problem of intentions of non-existent objects. In addition to an analysis facilitating understanding of the early phenomenology of Edmund Husserl, the book aims to draw attention to Brentano's philosophy, which was an important part of the German-written philosophy in Bohemia before the Second World War.
