Final answer:
Natural law is not strictly limited to observations from nature; it encompasses both scientific observations and ethical principles derived from human nature. Scientific laws can be revised with new evidence, while the ethical application of natural law depends on human interpretation, making the initial statement False.
Step-by-step explanation:
The statement that natural law is strictly limited to observations from nature is False. Natural law theory extends beyond mere observations of nature, as it integrates philosophical reasoning about human nature and ethics. The natural law refers to both the laws of the natural world as understood by scientists, and to a theory of ethics that posits the existence of a law whose content is set by nature and that therefore has validity everywhere. A scientific law is an observation of a pattern in nature, such as the law of gravitation, but it is also something that can be revised or replaced if new observations contradict it, making our understanding of natural and scientific laws an ever-evolving process.
For example, in the context of scientific methodology, when a theory has been known for a long time and consistently holds true under various experiments and observations, it does not become a law. A scientific law is a specific statement thought to never be violated by the natural universe, and it represents the highest understanding of the natural world that science has, albeit open to revision with new evidence. Scientific laws can be reevaluated and potentially changed or expanded upon if new evidence or observations are presented.
As for natural law within the realm of ethics, problems arise because people interpret nature differently. The natural law theory suggests that the moral law of human nature is knowable by natural human reason; however, what constitutes moral or ethical behavior can be subject to debate depending on different philosophical viewpoints. Therefore, the application of 'natural law' varies and is influenced by human perception and reason, not solely by nature itself.
