Real Laws
The relationships between material things are not less real than those things themselves. They are often formulated as so-called “laws”, in physics as laws of nature, for example.
Some of these laws are far from being obvious. It takes time to discover them; making use of them has to be learned, often bound up with special technical skills and equipment. Others, however, are grasped intuitively. We act in accordance with them naturally, long before they are recognized as regular patterns and formulated as laws.
