Abstract

We always have a close interaction with systematic nature. Most of our behaviors, plannings, predictions, as well as our ideas and beliefs are due to the fact that we consider nature as controlled by the laws. Since the laws of nature are the main keys of human sciences, analysis and explanation of these laws were a part of the research of many great philosophers such as Plato, Aristotle, Ibn Sina, Hume, Mullah Sadra and Kant. In this paper, while referring to some theories about the laws of nature, the author deals particularly with Hume’s standpoint, which is well-known as the viewpoint of “orderliness”; and then, he criticized it through distinguishing between perpetual propositions and necessary propositions.
