of the fundamental concepts used in this field, often in the form of conceptual analysis. This approach is particularly prominent in the analytic tradition. It aims to make ambiguities explicit and to uncover various implicit and potentially false assumptions associated with these terms. Theorists in this field often emphasize the importance of this form of investigation since all subsequent work on more specific issues already has to assume at least implicitly what their central terms mean to demarcate their field. For example, in order to study what constitutes good education, one has to have a notion of what the term "education" means and how to achieve, measure, and evaluate it. Definitions of education can be divided into thin and thick definitions. Thin definitions are neutral and descriptive. They usually emphasize the role of the transmission of knowledge and understanding in education. Thick definitions include additional normative components, for example, by stating that the process in question has to have certain positive results to be called education. According to one thick definition, education means that the person educated has acquired knowledge and intellectual skills, values these factors, and has thus changed for the better. These characteristics can then be used to distinguish education from other closely related terms, such as "indoctrination". Other fundamental notions in the philosophy of education include the concepts of teaching, learning, student, schooling, and rearing. Aims of education A central question in the philosophy of education concerns the aims of education, i.e. the question of why people should be educated and what goals should be pursued in the process of education. This issue is highly relevant for evaluating educational practices and products by assessing how well they manage to realize these goals. There is a lot of disagreement and various theories have been proposed concerning the aims of education. Prominent suggestions include that education should foster knowledge, curiosity, creativity, rationality, and critical thinking while also promoting the tendency to think, feel, and act morally. The individual should thereby develop as a person, and achieve self-actualization by realizing their potential. Some theorists emphasize the cultivation of liberal ideals, such as freedom, autonomy, and open-mindedness, while others stress the importance of docility, obedience to authority, and ideological purity, sometimes also with a focus on piety and religious faith. Many suggestions concern the social domain, such as fostering a sense of community and solidarity and thus turning the individual into
