This book provides a fresh perspective on how mathematicians interpreted and responded to Dutch mathematician L.E.J. Brouwers ideas. It offers an original outlook on the dynamics between mathematicians, their commitments to their working frameworks, and the establishment of scientific norms. Expanding on the collective scientific work literature, it prompts a dialogue on applying insights from social epistemology to mathematics, exploring whether such an approach can offer new insights into individual and communal responses to Brouwers intuitionistic pursuit. As a result, the book is of great value to those interested in STS studies, history and philosophy of science and sociology of science, delving into topics like the social construction of knowledge, epistemic cultures, and disagreements and trust in communities. Amid ongoing discussions about the marginalization and legitimization of knowledge, this book arrives just at the right time to offer a thorough exploration of the reasons behind the marginalization of a specific school in the history of mathematics.
