Abstract

It is an indubitable fact that our thoughts are always about something or some state of affairs in the world. Again, it is true that we use language to express some of our thoughts, and that in such a use of language which philosophers call a speech act, language also comes to be about something or some state of affairs in the world. E.g., when someone asserts that Peter is married to Mary, the sentence, 'Peter is married to Mary', comes to be about the state of affairs of Peter's being married to Mary. This property of being about something which characterizes our thoughts and speech acts is called "intentionality" by philosophers. ;In Intentionality, John Searle claims that the Intentionality of language and the Intentionality of speech acts performed by using language is derived from the intrinsic Intentionality of mental states which accompany the speech act. In the dissertation I propose to examine this claim of Searle's. ;Searle's view regarding the Intentionality of speech acts is incomplete and wrong. Searle does not show how the Intentionality of referring and predicating in a speech act is to be derived from mental reference and mental predication in the corresponding mental state. In this sense his theory is incomplete. Further, his theory is false. Taking the case of belief, I propose to show that it cannot be the source of the Intentionality of the corresponding assertion. Either a belief is a disposition and does not have any Intentionality or it is a mental act of accepting a proposition in which case the Intentionality of the belief and the Intentionality of the assertion have the same linguistic nature and the former cannot be the source of the latter. We are faced with a dilemma which shows that Searle's view cannot be correct. In the dissertation it will be argued that the Intentionality of a speech act is as intrinsic to it as the Intentionality of a mental phenomenon is to the mental phenomenon. The nature of speech act referring and predicating, mental referring and predicating, linguistic concepts and linguistic acts using those concepts will be discussed
