원론 (Elements) refers to the foundational principles or basic components that make up a particular field of study or system. In various disciplines, these elements serve as the building blocks for understanding more complex concepts. For example, in philosophy, 원론 might explore fundamental ideas about existence, knowledge, and ethics. In the context of science, 원론 can refer to the basic substances that cannot be broken down into simpler forms, such as 화학 원소 (chemical elements) like hydrogen and oxygen. Understanding these elements is crucial for studying chemical reactions and the composition of matter.
