Two dimensionalism is an explanatory approach in analytic philosophy. The term 'Two-dimensionalism' was first used by Robert Stalnaker. The characteristic feature of the two-dimensionalist approach is its appeal to two separately contributing accounts of a philosophical problem. On two-dimensional approaches, each contributing account is a dimension of the complete explanation.

  • Two dimensionalism is an explanatory approach in analytic philosophy. The term 'Two-dimensionalism' was first used by Robert Stalnaker. The characteristic feature of the two-dimensionalist approach is its appeal to two separately contributing accounts of a philosophical problem. On two-dimensional approaches, each contributing account is a dimension of the complete explanation. For example, in the philosophy of language, two-dimensional accounts often include a description-based dimension and a reference-based dimension. This can be illustrated with the assertion (from the Twin Earth thought-experiment) Water is H2O. According to a straightforward two-dimensionalist account, this sentence has two meanings. Along one semantic dimension (the primary intension), "water" is interpreted in terms of a description, such as "transparent liquid found in lakes and rivers". The thing picked out by the primary intension of "water" might have been otherwise, for example, on some other planet where the chemical make-up of the transparent liquid found in lakes and rivers is not H2O, water is not H2O. Along the other semantic dimension (the secondary intension), water is whatever "water" happens to pick out in this world. The secondary intension of "water" relative to our world is H2O, unequivocally. Considered along this dimension, water means H2O in every world. In addition to the philosophy of language, two-dimensional approaches have been used in modal logic, metaphysics, philosophy of mind, and ethics.
