Philosophical method (or philosophical methodology) is the study of how to do philosophy. A common view among philosophers is that philosophy is distinguished by the ways that philosophers follow in addressing philosophical questions. There is not just one method that philosophers use to answer philosophical questions. Philosophical method (or philosophical methodology) is the study of how to do philosophy.

There is not just one method that philosophers use to answer philosophical questions. Systematic philosophy attempts to provide a framework in reason that can explain all questions and problems related to human life. Examples of systematic philosophers include Plato, Aristotle, Descartes, Spinoza, and Hegel. In many ways, any attempts to formulate a philosophical method that provides the ultimate constituents of reality, a metaphysics, can be considered systematic philosophy. In modern philosophy the reaction to systematic philosophy began with Kierkegaard and continued in various forms through analytic philosophy, existentialism, hermeneutics, and deconstructionism.
