Abstract

Philosophy is an abstract theoretical discipline. However, a new trend that develops experimental methods in philosophical research has recently been gaining popularity extending to the fields of philosophical research that have not seen experimental methods earlier. This article addresses the question of whether it is possible to investigate philosophical questions with empirical methods. Two areas of research are considered – philosophy of language and semantics and epistemology. In these subfields of philosophy, the application of experimental methods has recently lead to a noticeable progress. Empirical methods are justified in those disciplines in which arguments in favor of a particular theory are based on the study of our intuitions. Experiments only serve to obtain more objective representations of our intuitions, and philosophical argumentation is built further based on these intuitions. The authors argue that the use of experimental methods in semantics is compatible with anti-psychologism about meaning. The latter point is particularly controversial because linguistic intuitions or intuitions about the meaning have often been viewed as something that speakers have clear cognitive access to. However, when experimental research (even when it is a collection of controlled judgments) shows results that are different from what the field has been previously assuming, a revision is called for. The authors review several cases of such refutations calling for further revisions and argue that such experimental work helps arguments in philosophy of language and epistemology gain more sound ground with respect to the empirical data that they build on. In philosophy of language and theoretical linguistics, the cases explored in this article relate to the differences between languages with and without articles and to the predictions about the availability of certain interpretations of such expressions or lack thereof. It is further shown how a similar method of identifying the existent or non-existent interpretations was used in the studies of the meaning of “most”. In epistemology, the article discusses the results of some recent experimental work relating to the knowledge ascriptions. The speakers’ intuitions about the famous Barn-examples have recently been shown to diverge from what philosophers have claimed, building their far-reaching arguments on the data that was arguably incorrect.
