Chad Hansen is a contemporary analytic philosopher specializing in classical Chinese philosophy, best known for applying philosophy of language to the interpretation of ancient Chinese thought. He developed the influential 'mass noun hypothesis,' arguing that the count/mass noun distinction in classical Chinese shaped its metaphysical and ethical frameworks in ways fundamentally different from Western traditions. His work has reframed debates about figures such as Laozi, Zhuangzi, Mencius, and Xunzi.
