'Bert Cappelle engages critically and sometimes ruthlessly with foundational aspects of CxG, arguing for a rigorous scientific approach that emphasizes falsifiability, empirical testing and openness to alternative perspectives. While he acknowledges the successes and contributions of CxG, he also highlights the importance of addressing its limitations and fostering collaborative discussions with diverse linguistic frameworks. The book serves as a call to action, if not a wake-up call, for Construction Grammarians, encouraging them to scrutinize and refine their theoretical commitments while embracing the complexities of language. In doing so, it stands as a thoughtful and thought-provoking contribution to ongoing discussions within the field of CxG. It is an honest, constructive and optimistic critique, offering guidelines for how the theory can further mature and enhance its standing within the overall scientific framework.'
