What is a concept? It sounds simple until you try to answer it. In The Shape of Meaning, Marcus Qadar dissects the hidden machinery of thought itself. Concepts are the invisible structures that let us think, speak, judge, and argue, yet they quietly distort reality even as they make it intelligible. This book explores how concepts are formed, where they exist, how they fail, and why bad concepts quietly poison entire systems. Part philosophy, part intellectual autopsy, this is a rigorous, unsettling examination of the mental scaffolding we live inside and rarely question.
