Final answer:
The concept of natural law suggests that there are universal and inalienable moral principles inherent in human nature, discernible through reason, which is true. However, its application can be contentious due to differing interpretations of human nature and the role of environmental factors.
Step-by-step explanation:
The statement 'Natural law refers to universal moral principles that are not specifically derived from special revelation' is true. Natural law is grounded in the notion that there are universal ethical principles inherent in human nature, that we can discern through reason and observation, not just through divine or supernatural revelation. These moral principles are considered universal because they are not contingent on human laws or customs, making them universal and inalienable rights. The natural law theory, which has been influential from classical antiquity through the Enlightenment and up to today, posits that actions in harmony with these natural laws are inherently moral.
Yet, natural law theory faces challenges when various interpretations of nature lead to conflicting moral conclusions. Furthermore, natural law has been scrutinized due to evolving understandings of human nature and behavior as influenced by biology and environment, questioning the inherent moral order suggested by classical natural law theorists.
