““Moreover, philosophizing—if by that we broadly mean the critical investigation of deeply perplexing questions, such as what is the best way to live, what is true and how can we best know it, and what are our obligations to one another—is a widespread and perhaps even universal phenomenon, especially among highly literate cultures. There is no a priori reason, therefore, to say that philosophy is limited to the way it has been construed in any one cultural context, whether it be the classical cultures of the Mediterranean basin or the modern cultures of the so-called western world. Rather, the challenge is to understand the context and rules of philosophizing in a variety of sometimes radically different environments. We can only judge how good a philosophical answer is after we are sure we have understood the question the answer is addressing. To do so, the most important thinkers to study are those who develop systematic philosophical articulations rather than ad hoc solutions to particular isolated issues. By understanding the projects of critical, systematic thinkers, we are better equipped to uncover the premises and rules of reasoning that inform their answers.””
