Psychologie Und Logik: Zur Einführung in Die Philosophie

A scientific publication written in the early 20th century. The work serves as an introductory text designed for upper-level secondary school students and self-study, exploring the foundational concepts of philosophy, psychology, and logic. Elsenhans discusses the relationship between these fields and the importance of understanding their principles for a comprehensive grasp of philosophical inquiry. The opening of the book begins with an introduction that outlines the purpose of philosophy as a discipline that aims to establish unity and coherence in knowledge. Elsenhans emphasizes that philosophy arises from the need to address contradictions within knowledge and facilitates a deeper inquiry into the conditions of understanding. He categorizes philosophy broadly into natural philosophy and the philosophy of mind, or psychology, and highlights the interconnectedness of these domains. The introduction sets the stage for a systematic exploration of psychological phenomena, the relationship between mind and body, and the principles of logical reasoning, which will be discussed in detail in subsequent sections.
