A philosophical theory is a structured and coherent system of ideas and arguments developed to explain, interpret, or analyse concepts related to fundamental questions about reality, existence, knowledge, values, mind, language, and the nature of human life. Philosophical theories are based on rational thought, critical analysis, and logical reasoning, rather than empirical observation, although they can be informed by empirical data.
Philosophical theories serve various functions, including:
Explanation
Frameworks for Thought
Critical Evaluation
