The article discusses Hartmann's idea of "Metaphysics of knowledge", which focuses on the difference between how we understand things and how we know about them. Hartmann suggests that some problems can't be solved just by studying knowledge itself, but require looking at the nature of things. He introduces the concept of "metaphysics of standpoint" to address this. By emphasizing the importance of understanding phenomena, even if they can't be fully explained, Hartmann aims to provide a framework for broader philosophical discussions. The article questions whether switching from studying knowledge to studying the nature of things can solve complex problems or if it just adds more complexity.
