Procedural knowledge in molecular biology
-
Abstract:
A crucial part of the knowledge of molecular biologists is procedural
knowledge, that is, knowledge of how to do things in laboratories.
Procedural knowledge of molecular biologists involves both perceptual-motor
skills and cognitive skills. We discuss such skills required in performing
the most commonly used molecular biology techniques, namely, PCR and gel
electrophoresis. We argue that procedural knowledge involved in performing
these techniques is more than just knowing their protocols. Creative
exploration and experience are essential for the acquisition of procedural
knowledge in molecular biology. With enough experience, molecular biologists
make intuitive judgments without recourse to analytical reasoning. We propose
that procedural knowledge is intuitive recognition of the patterns of one's
environment that are the most relevant for making a decision or acting
appropriately. Finally, we argue that knowledge of molecular biologists
requires an integration of procedural knowledge and propositional knowledge.

Simulation and connectionism: What is the connection?
-
Abstract:
Simulation has emerged as an increasingly popular account of folk psychological
(FP) talents at mind reading: predicting and explaining human mental states.
Where its rival (the theory-theory) postulates that these abilities are
explained by mastery of laws describing the connections between beliefs,
desires, and action, simulation theory proposes that we mind-read by "putting
ourselves in another's shoes." This paper concerns connectionist architecture
and the debate between simulation theory (ST) and the theory-theory (TT).
It is only natural to associate TT with classical architectures where rule
governed operations apply to explicit propositional representations. On the
other hand, ST would seem better tuned to procedurally oriented non symbolic
structures found in connectionist models. This paper explores the possible
alignment between ST and connectionist architecture. Joe Cruz argues that
connectionist models with distributed non-symbolic representations are
particularly well suited to simulation theory. The purported linkage
between connectionist architecture and simulation theory is criticized in
this paper. The conclusion is that there are reasons for thinking that
connectionist forms of representation are the enemy of both TT and ST.
So the contribution of connectionism may be to suggest the need for an
alternative to both views.

Projectivist representationalism and color
-
Abstract:
This paper proposes a subjectivist approach to color within the framework of
an externalist form of representationalism about phenomenal consciousness.
Motivations are presented for accepting both representationalism and color
subjectivism, and an argument is offered against the case made by Michael
Tye on behalf of the claim that colors are objective, physical properties
of objects. In the face of the considerable difficulties associated with
finding a workable realist theory of color, the alternative account of color
experience set out, projectivist representationalism, claims that the color
properties we encounter in experience exist only in the representational
contents of our experiences. Color experiences are caused by the physical
structure of objects, but objects are never actually colored and color
experiences systematically misrepresent objects as colored. However, despite
being an error theory of color, projectivist representationalism does not do
violence to our everyday use and understanding of color concepts and terms,
nor does it undermine the role of color experience in aiding the perceiving
subject in navigating through the world.

Mythological content: A problem for Millikan's teleosemantics
-
Abstract:
I pose the following dilemma for Millikan's teleological theory of mental
content. There is only one way that her theory can avoid Gauker's (1995)
charge that it relies on an unexplained notion of mapping or isomorphism
between mental state and world. Mental content must be explained in terms
of the mapping relation that is required for mental state producing and
consuming mechanisms to perform their biologically proper functions, i.e.,
producing mental states that are consumed in systematically adaptive
practical inferences. However, this proposal leads to unacceptably
counter-intuitive ascriptions of content to mythological beliefs and related
desires: such beliefs and desires must 'map onto' environmental states that
make them adaptive, not onto the mythological states of affairs that (would)
make them true or fulfilled. I conclude by discussing the merits and
drawbacks of a potential solution to this problem: the view that the
contents of mythological beliefs and desires are determined by the
non-mythological concepts out of which they are constructed, rather than
by the environmental states that make them adaptive. The affinities of
this proposal with Pascal Boyer's recent (2001) theory of mythological
concepts are also discussed.
Discussion: Social Psychology and the Authorship Account of First-person Authority
KRISTA LAWLOR
Elusive reasons: A problem for first-person authority
-
Abstract:
Recent social psychology is skeptical about self-knowledge. Philosophers, on the other hand, have produced
a new account of the source of the authority of self-ascriptions. On this account, it is not descriptive
accuracy but authorship, that funds the authority of one's self-ascriptions. The resulting view seems to
ensure that self-ascriptions are authoritative, despite evidence of one's fallibility. However, a new wave
of psychological studies presents a powerful challenge to the authorship account. This research suggests
that one can author one's attitudes, but one's self-ascriptions may lack authority. I present this new
challenge from social psychology and use it to argue that first-person authority is agential authority:
one's self-ascriptions are authoritative, in part anyway, because they are reliable expressions of those
attitudes that govern further choices and behavior.

An elusive challenge to the authorship account: Commentary on Lawlor's "Elusive Reasons"
-
Abstract:
Lawlor argues that social psychological studies present a challenge to the authorship account of
first-person authority. Taking the deliberative stance does not guarantee that self-ascriptions
are authoritative, for self ascriptions might be based on elusive reasons and thus lack agential
authority (i.e., they are no guide to the subject's future conduct). I argue that Lawlor's challenge
is not successful. I claim that we can make sense of the nature and importance of agential authority
only within the framework of the authorship account. Agential authority is part of the regulative
ideal of the deliberative stance, but its lack does not undermine the first-person authority of
self-ascriptions, since first-person authority is primarily a matter of deliberative authorship.

Deliberation and agential authority: A rejoinder to Ferrero
-
Abstract:
My reply to Ferrero is divided into three parts: a recap of my argument and claim, a response to
Ferrero's central criticism, and, finally, a question about his attempted defense of the authorship
account.
