Abstract
The book is an English translation with revisions and updates of the "Philosophische Grundbegriffe 1" (8th edition, 2009) and provides an introduction to six key concepts in philosophy: philosophy, language, knowledge, truth, being and good. At the same time, it aims to initiate its readers into the process of philosophical thinking. The book is addressed to students and laypeople, but also contains new ideas for specialists. It is written in a clear, accessible and engaging style, and its author 'shares, and manages to convey, something of Plato's own commitment to philosophy' (Phronesis).
