abstract

Abstraction is a cognitive process where a common feature or relationship is identified from multiple observations. For example, the concept of "being longer than" is abstracted from observing pairs of lines where one is longer than the other. This process is crucial for higher cognitive functions like forming judgments and learning from experience.1

In philosophy, "abstract" refers to general characters or kinds, contrasting with "concrete" entities like specific objects or events. For instance, "war" is abstract, while "World War I" is concrete. Abstract entities are often considered not to exist in space or time, such as numbers or properties.12

Philosophy itself is the rational, abstract, and methodical consideration of reality and fundamental aspects of human existence. It explores profound questions that may eventually become subjects of science, psychology, or mathematics. Key branches include metaphysics, epistemology, ethics, and the philosophy of science, which examines scientific inquiry from a philosophical viewpoint.345
