Final answer:
According to the Natural Law tradition, knowledge of basic moral laws is obtained through human reason. Humans are morally obligated to use their reasoning to discern the laws and act in accordance with them. However, challenges arise from differing interpretations of nature and subjective understandings of morally praiseworthy traits of human nature.
Step-by-step explanation:
According to the Natural Law tradition, knowledge of basic moral laws is obtained through human reason. The Natural Law view suggests that humans have the ability to reason and discern the Laws of Nature through their rationality. It is the responsibility of humans to use their reasoning to discover these laws and act in accordance with them.
However, there are challenges to the Natural Law theory. Different interpretations of nature can lead to varying understandings of moral laws. Additionally, determining the morally praiseworthy traits of human nature can be subjective. Critics argue that human behavior is influenced by environmental factors, which complicate the establishment of universal laws of behavior based solely on human nature.
