Definition: Abstraction refers to a principle or idea that has no physical representation, but is related to objects or concepts through common properties, features, qualities, or symbols. It is not an object itself but rather a characteristic, attribute, or quality that exists in all forms of being. Abstractions help us understand complex ideas by breaking them down into simpler elements or principles. ### Definition Abstraction refers to the process of identifying and simplifying complex concepts or ideas so they can be understood more easily and efficiently. It involves recognizing the underlying structure or features that underlie objects or concepts, rather than directly observing the physical object itself. The goal is to simplify these abstract constructs into a single, manageable component or characteristic. For example, if we want to understand how the human body works, abstraction might involve looking at the heart's main structures like valves and arteries as simple units rather than elaborate systems of blood vessels and muscle fibers. In this case, understanding the functions of these key components is more directly related to what the heart does than directly observing its structure. Abstractions can be applied to any situation where a concept is abstract and has no tangible representation or physical embodiment, such as in art, architecture, technology, and philosophy.
