The emergence of ChatGPT has sparked widespread academic attention. This lecture will explore ChatGPT’s technical principles and the philosophical debates it has ignited. First, we will introduce the technical framework of ChatGPT, including its Transformer-based pretrained technology, code training, and alignment with human intentions. Next, we will examine the philosophical controversies and challenges it poses to scholars, covering topics such as: Is ChatGPT intelligent? Does it possess consciousness? Can it perform causal reasoning? What are the implications for debates between rationalism and empiricism? How does ChatGPT challenge theories in philosophy of language?
