This text explores the nature of concepts and conceptuality, based on the premise that concepts are a human invention rather than a discovery. The author argues that an invention truly becomes such only through repeated and purposeful application. Concepts are characterized as a unique "trick" that individuals learn to use intuitively, often without a profound understanding of their inner workings. From this perspective, the contribution of Ancient Greece is re-evaluated; the Greeks may not have invented concepts themselves, but they pioneered a brilliant application of conceptual thinking to human existence, leading to the birth of philosophy. The definitive turning point occurred when philosophical reflection, already utilizing concepts, turned its focus back onto conceptuality itself. Philosophy is thus presented not merely as a consequence of having concepts, but as a deliberate project of applying them to specific situations and eventually thematizing their own nature. This transition from intuitive use to reflexive conceptualization marks a fundamental shift in human intellectual history.
