Introduction

History and philosophy of science (HPS) has been controversial since its birth. In particular, the legitimacy of its status as an academic discipline has been constantly challenged and questioned. Nevertheless, substantial hope for HPS as a productive academic discipline is not dead. Some historically-minded philosophers of science and philosophically-minded historians of science never stop making efforts to promote the dialogue across the boundaries and defend HPS against the challenges in various ways. Integrated history and philosophy of science (integrated HPS) is such an attempt. It aims at a balanced inquiry from which both history of science and philosophy of science can benefit. In a nutshell, integrated HPS maintains that HPS should be both a good philosophy of science and a good history of science at the same time.
