Psychologie und Logik: zur Einführung in die Philosophie

A concise, early‑20th‑century guide opens with a clear statement of philosophy’s purpose: to bring safety, unity and coherence to every field of knowledge. From that premise it moves through a brief history of philosophical thought before turning to the twin pillars of the mind’s study—psychology and logic. The author treats the relationship between soul and body, perception, feeling and volition in a way that is both systematic and approachable for advanced school students.

The second half shifts to logic, laying out the fundamentals of terms, judgments and various forms of inference, from simple syllogisms to more complex indirect arguments. Throughout, practical examples illustrate common mistakes in reasoning and how to avoid them. By the end of the first part, listeners will have a solid framework for exploring deeper philosophical questions with a disciplined, analytical mindset.
