The natural laws are in effect at all times. They do not know cultural, ethnic, religious, social, educational, or economic differences. They do not discern between young and old, rich and poor. They only know equality. This premise, in itself, suggests the great benefit man will gain as he familiarizes himself with these eternal principles. It is especially important as he will not avoid being affected by them. What are these natural laws? Who created them? How do they work? Are they changeable? Have they always been in effect? Are some laws more powerful than others? How can we make them work for us? How are the natural laws different from man's laws? Do they work in all areas of life? Discovering how these natural laws work will be a very valuable tool of self-empowerment for anyone who wishes to create a happy and fulfilled life.

Sir Isaac Newton changed the world with his many discoveries and inventions about mathematics, science, optics, and physics. Although he was brilliant, Newton felt no need to publish his ideas or to inform his fellow scientists of the amazing discoveries he made. Because of this, his discoveries were often disputed. Despite the controversy that often surrounded him, Newton made astounding advances in his efforts to understand how nature worked. His legacy lives on through inventions such as microscopes, eyeglasses, telescopes, and cameras.

An account of a fundamental change in American legal thought, from a conception of law as something found in nature to one in which law is entirely a human creation. Before the late 19th century, natural law played an important role in the American legal system. Lawyers routinely used it in their arguments and judges often relied upon it in their opinions. Today, by contrast, natural law plays virtually no role in the legal system. When natural law was part of a lawyer's toolkit, lawyers thought of judges as finders of the law, but when natural law dropped out of the legal system, lawyers began thinking of judges as makers of the law instead. In The Decline of Natural Law, the eminent legal historian Stuart Banner explores the causes and consequences of this change. To do this, Banner discusses the ways in which lawyers used natural law and why the concept seemed reasonable to them. He further examines several long-term trends in legal thought that weakened the position of natural law, including the use of written constitutions, the gradual separation of the spheres of law and religion, the rapid growth of legal publishing, and the position of natural law in some of the 19th century's most contested legal issues. And finally, he describes both the profession's rejection of natural law in the late 19th and early 20th centuries and the ways in which the legal system responded to the absence of natural law. The first book to explain how natural law once worked in the American legal system, The Decline of Natural Law offers a unique look into how and why this major shift in legal thought happened, and focuses, in particular, on the shift from the idea that law is something we find to something we make.

It is often presumed that the laws of nature have special significance for scientific reasoning. But the laws' distinctive roles have proven notoriously difficult to identify--leading some philosophers to question if they hold such roles at all. This study offers original accounts of the roles that natural laws play in connection with counterfactual conditionals, inductive projections, and scientific explanations, and of what the laws must be in order for them to be capable of playing these roles. Particular attention is given to laws of special sciences, levels of scientific explanation, natural kinds, ceteris-paribus clauses, and physically necessary non-laws.

This book examines the relationship between humans and nature that evolved in medieval Europe over the course of a millennium. From the beginning, people lived in nature and discovered things about it. Ancient societies bequeathed to the Middle Ages both the Bible and a pagan conception of natural history. These conflicting legacies shaped medieval European ideas about the natural order and what economic, moral and biological lessons it might teach. This book analyzes five themes found in medieval views of nature – grafting, breeding mules, original sin, property rights and disaster – to understand what some medieval people found in nature and what their assumptions and beliefs kept them from seeing.

'Natural Law in the Spiritual World', written in the 1800s by Henry Drummond, delves into how the natural laws of the universe apply to the world of spirit. The book presents spiritual insights in an easy-to-understand manner, making it accessible to readers of different backgrounds. There are chapters dedicated to topics such as biogenesis, abiogenesis, degeneration, reversion to type, and more. The book may be a little wordy in places, but it is spiritually poetic and beautiful. Ultimately, it provides insight into the importance of God and the eternal nature of the soul.
