The aim of this paper is to analyze the phenomenon related to business ethical purposes from a different perspective, using the philosophical lens developed by Immanuel Kant. This work is also oriented to identify the most important research topics related to business ethics through the combination of a different framework. The present paper intends to offer a conceptual contribution to the ongoing debate on the theme of ethics in corporate social responsibility, highlighting the main problematic aspects that emerge from the analysis of the literature and the observation of reality in the light of the philosophical framework of Kant. This paper, therefore, examines and applies the deontological view of Kant and his distinction between the ‘categorical’ and ‘hypothetic’ imperative. This ethical view is useful to prevent instrumental acceptance of ethical codes and sustainability reports; in fact, during the making of the work, several well-known practices are presented, which are far from behaving in a moral way (i.e., General Electrics, Lehman Brothers, and so on).
