The aim of science is to discover natural law, or to explain the consistency of things that we know through our senses. Whereas the essence of sense and natural law themselves still remain many problems waited to explore clearly even in today. By logic analysis and review some theories, especially phenomenology, this paper reaches conclusion that natural law in essence is subject's dimension and subjective logic form which can spread things out, objectively define things and represent them in mind. The scientific model is a logical metaphor that blends the concepts of common experience with priori form.

Similarity is demonstrably important across many areas of cognition. At present, the main idea is that the similarity of a pair of objects increase with its commonalities and decrease with its difference. However, it's difficult to reasonably explain some counterintuitive situations that often occur. For example, people might find that someone looks similar with a dog, even though most shared features are dissimilar. Inspired by the ideas of form and spirit, we speculate that some key features of objects may have a greater impact on similarity judgment than the others. Therefore, this paper proposed a theoretical model of similarity judgment to illustrate the counterintuitive situation, indicating hierarchical or primary-secondary relationship among shared features between objects, expanding the scope of existing similarity theories. This model has potential applications in many aspects such as the development and protection of intellectual property, product design, game and film industries and so on.
