The authors argue that Lee and George (hereafter, L/G) use a reductionist anthropology and ethical method to defend a classicist approach to absolute sexual norms. After describing Lonergan’s understanding of scotosis, which can distort one’s insight into ethical theory and ethical issues, the article demonstrates this distortion in L/G’s sexual anthropology. It further argues that, in formulating their sexual anthropology, L/G fail to address the significance of sexual orientation, and that their method inadequately integrates human experience and reason as sources of moral knowledge.
