The Rector and Permanent Fellows of COLLEGIUM BUDAPEST / Institute for Advanced Study invite you to a Public Lecture by Derek Bickerton on Thursday, 25 April 2002, at 5.30 p.m. in Collegium Budapest 1014 Budapest Szentháromság u. 2. "If you can't make a sentence you can't make sense: The real relation between thought and language" The relationship between thought and language has been systematically misunderstood by almost everyone who has ever written about it. First, the two categories are incommensurate. Language does not admit of gradation or qualification—something either is language or it isn't. Thought on the other hand can appear in a variety of forms. It can be conscious or unconscious. It can be on-line or off-line. It can be directed or undirected. There is probably only one kind of thought that requires language, that is, conscious, off-line, directed thought. Directed thought requires that symbolic units of some kind be manipulated. We tend to think of these as 'words' because that's what they are when we utter or write our thoughts. If they remain in the brain they aren't words because there are no words in the brain, only electrochemical impulses. If we think of these things as 'concepts' we fall into the trap of thinking that on the one hand there are words and on the other concepts and the former simply consist of some kind of clothes for the latter. Because again there aren't 'concepts' in the brain—only electrochemical impulses. It helps if we say that whether we thinking ot speaking, we are simply manipulating symbolic units (of some sort). In order for those symbols to result in any kind of meaning –that is, in order for them to constitute conscious, off-line, directed thought--they have to be assembled in some structured kind of way. Syntax—what makes grammatical sentences—is the only way of structuringsymbolic units. That there are two ways of putting them together—some mysterious 'language of thought' as opposed to some specific human language—seems to be incorrect. Basic principles of syntax common to all languages serve to structure symbolic units BEFORE those units achieve morphological or phonological expression. The same process that enables us to speak in sentences is what enables us to have the kind of sirected thoughts that make us human—'I talk, therefore I think'.
