Chapter THE NATURE OF INTENTIONAL STATES I. INTENTIONALITY AS DIRECTEDNESS As a preliminary formulation we might say: Intentionality is that property of ...

In philosophy the term intentionality refers to the feature possessed by mental states of beingabout things others than themselves. A serious question has been how to explain the intentionality of mental states. This paper starts with linguistic representations, and explores how an organism might use linguistic symbols to represent other things. Two research projects of Sue Savage-Rumbaugh, one explicity teaching twopan troglodytes to use lexigrams intentionally, and the other exploring the ability of several members ofpan paniscus to learn lexigram use and comprehension of English speech spontaneously when raised in an appropriate environment, are examined to explore the acquisition process. Although it is controversial whether intentionality of mental states or linguistic symbols is primary, it is argued that the intentionality of linguistic symbols is primary and that studying how organisms learn to use linguistic symbols provides an avenue to understanding how intentionality is acquired by cognitive systems.

After a brief history of Brentano's thesis of intentionality, it is argued that intentionality presents a serious problem for materialism. First, it is shown that, if no general materialist analysis (or reduction) of intentionality is possible, then intentional phenomena would have in common at least one nonphysical property, namely, their intentionality. A general analysis of intentionality is then suggested. Finally, it is argued that any satisfactory general analysis of intentionality must share with this analysis a feature which entails the existence of a nonphysical "level of organization".

One of the most enduring elements of Davidson’s legacy is the idea that intentionality is inherently normative. The normativity of intentionality means different things to different people and in different contexts, however. A subsidiary goal of this paper is to get clear on the sense in which Davidson means the thesis that intentionality is inherently normative. The central goal of the paper is to consider whether the thesis is true, in light of recent work on intentionality that insists on an intimate connection between intentionality and phenomenal consciousness. According to several recent authors, there is a kind of intentionality – “phenomenal intentionality” – that is fully constituted by the phenomenal character of conscious experiences. I will argue that although Davidson’s thesis, when correctly understood, is compelling for most intentionality, it is false of phenomenal intentionality. I start, in §1, with an explication of the notion of phenomenal intentionality; in §2, I elucidate Davidson’s thesis and his case for it; in §3, I argue that the case does not extend to phenomenal intentionality; I close, in §4, with some objections and replies.

Approach to Intentionality is an authoritative and accessible account of a problem central to contemporary philosopy of mind. Lyons first gives a critical survey of the current debate about the nature of intentionality, then moves on to offer an original new theory. The book is written throughout in a clear, direct, and lively style.

Tomasello et al. give a good account of how shared intentionality develops in children, but a much weaker one of how it might have evolved. They are unduly hasty in dismissing the emergence of language as a triggering factor. An alternative account is suggested in which language provided the spark, but thereafter language and shared intentionality coevolved.
