Theory is the process of abstraction and rational contemplation of ideas. In simple terms, it can be see as "thinking about thinking".

Theory in a philosophical sense does not require empirical data to support their premises and conclusions. Theory in a scientific sense does require empirical data.

Philosophical theory

In analytic philosophy, theory is reserved for systematic attempts to solve problems or answer a question [1] However, non-analytic philosophy can also be referred to any solution to a problem.

Examples of theory:

  • Ethical theory are positions taken about the nature of ethical statements [2]
  • Political theory are positions that ground and support a larger political ideology. See John Rawls as an example of this.
