{\bf Abstract} 
\begin{itemize}
\item Language is a tool: not only for communication, \\ 
	$\Rightarrow$ also for thinking \medskip
\item The Extended mind: Cognition is not only in the brain, \\
	$\Rightarrow$ also in our tools \medskip 
\item No need for nativism: language introduces new concepts to us \\
	in a prepackaged format \medskip

{\bf Supra-Communicative views on Language}
%(ie., language is more than communication)
\bigskip

``Vygotsky [...] pioneered the idea that language has a profound effect on
cognitive development'' \medskip
\begin{description}
\item[inner speech]
	$\Rightarrow$ eg., rehearsing steps to solve a problem
\item[scaffolded action]
	$\Rightarrow$ reliance on external support \\
	(tools, knowledge, skills etc.)
\end{description}

Dennett: 
\begin{itemize}
\item speaking affects the behavior of others, but also of ourself! \medskip

\item learning language means reprogramming the mind: \\
	$\Rightarrow$ language as serial machine implemented on a
	connectionist architecture.
\end{itemize}

{\bf Six ways in which language augments human computation}

\begin{itemize}
\item memory augmentation

\item environmental simplification

\item coordination and the reduction of on-line deliberation

{\bf Six ways in which language augments human computation (continued)}
\bigskip
\begin{itemize}
\item taming path-dependent learning
\medskip
\item attention and resource allocation
\medskip
\item data manipulation and representation

{\bf Meta-cognition: thinking about thinking}
\begin{quote}
``Public language and the inner rehearsal of sentences would, on this model,
act like the aerial roots of the Mangrove tree -- the words would serve as
fixed points capable of attracting and positioning additional intellectual
matter, creating the islands of second-order thought so characteristic of the
cognitive landscape of homo sapiens.''
\end{quote}
\end{frame}

\begin{frame}
{\bf The extended mind}
Where does the mind end and the world begin?
\begin{itemize}
\item `Internal' representations piggyback on external tools: \\
	$\Rightarrow$ `internal code' is not universal nor a `language of
	thought' \\
	$\Rightarrow$ why would we need a strict separation between data and
	process?
\medskip
\item Language is the crystallization of centuries of wisdom and thought: \\
	$\Rightarrow$ language crosses the boundaries between mind, body and
	world
\end{itemize}
