What are examples of recurrent truths?

Recurrent truths are principles or observations that consistently hold across different contexts and times. Examples include the law of gravity, which always dictates that objects fall toward the Earth, or the principle of supply and demand in economics, which influences market behavior. Additionally, fundamental human experiences, such as the inevitability of aging or the pursuit of happiness, are also considered recurrent truths. These truths provide a reliable framework for understanding the world.
