In the general sense, a philosophical theory[1] is a theory that explains or accounts for a general philosophy or specific branch of philosophy.[2] While any sort of thesis or opinion may be termed a theory, in analytic philosophy it is thought best to reserve the word "theory" for systematic, comprehensive attempts to solve problems.[3]

The elementary theorems that comprise a philosophical theory consist of statements which are believed to be true by the thinkers who accept them, and which may or may not be empirical. The sciences have a very clear idea of what a theory is; however in the arts such as philosophy, the definition is more hazy.[1] Philosophical theories are not necessarily scientific theories, although they may consist of both empirical and non-empirical statements.

In essence, the collective statements of all philosophical movements, schools of thought, and belief systems consist of philosophical theories. Also included among philosophical theories are many principles, hypotheses, rules, paradoxes, laws, as well as 'ologies, 'isms, 'sis's, and effects.[1]

Some examples of philosophical theories include:

  • Metatheory; theories about the formation and content of theories, such as Kurt Gödel's incompleteness theorem.
  • Political theory; theories that underlie a political philosophy, such as John Rawls' theory of justice.
  • Ethical theory and meta-ethics; theories about the nature and purpose of ethical statements,[4] such as the ethical theory of Immanuel Kant.
  • Critical theory; in its narrow sense, a Western European body of Frankfurt School Marxist thought that aims at criticizing and transforming, rather than merely explaining, social structures.[5] In a broader sense, "critical theory" relates to a wide variety of political, literary, and philosophical positions that take at least some of their inspiration from the Frankfurt School and its dialectic, and that typically contest the possibility of objectivity or aloofness from political positions and privileges.[6]

Philosophical theories may also take the form of a life stance, religion, world view, or ideology.

A scientific theory however, is a well-substantiated explanation of some aspect of the natural world based on a body of facts that have been repeatedly confirmed through observation and experiment. To become a scientific theory there are also specific requirements including that they can make predictions, are well supported by many fields of science, are consistent with preexisting theories, and they can be modified to account for new evidence.
