Can Intellectual Processes in the Sciences Also Be Simulated? The Anticipation and Visualization of Possible Future States
Socio-cognitive action reproduces and changes both social and cognitive
structures. The analytical distinction between these dimensions of structure
provides us with richer models of scientific development. In this study, I
assume that (i) social structures organize expectations into belief structures
that can be attributed to individuals and communities; (ii) expectations are
specified in scholarly literature; and (iii) intellectually the sciences
(disciplines, specialties) tend to self-organize as systems of rationalized
expectations. Whereas social organizations remain localized, academic writings
can circulate, and expectations can be stabilized and globalized using
symbolically generalized codes of communication. The intellectual
restructuring, however, remains latent as a second-order dynamics that can be
accessed by participants only reflexively. Yet, the emerging "horizons of
meaning" provide feedback to the historically developing organizations by
constraining the possible future states as boundary conditions. I propose to
model these possible future states using incursive and hyper-incursive
equations from the computation of anticipatory systems. Simulations of these
equations enable us to visualize the couplings among the historical--i.e.,
recursive--progression of social structures along trajectories, the
evolutionary--i.e., hyper-incursive--development of systems of expectations at
the regime level, and the incursive instantiations of expectations in actions,
organizations, and texts.Comment: accepted for publication in Scientometrics (June 2015
Do we need dynamic semantics?
I suspect the answer to the question in the title of this paper is no. But
the scope of my paper will be considerably more limited: I will be concerned
with whether certain types of considerations that are commonly cited in
favor of dynamic semantics do in fact push us towards a dynamic semantics.
Ultimately, I will argue that the evidence points to a dynamics of discourse
that is best treated pragmatically, rather than as part of the semantics
Epistemic NP Modifiers
The paper considers participles such as "unknown", "identified" and
"unspecified", which in sentences such as "Solange is staying in an unknown
hotel" have readings equivalent to an indirect question "Solange is staying in
a hotel, and it is not known which hotel it is." We discuss phenomena including
disambiguation of quantifier scope and a restriction on the set of determiners
which allow the reading in question. Epistemic modifiers are analyzed in a DRT
framework with file (information state) discourse referents. The proposed
semantics uses a predication on files and discourse referents which is related
to recent developments in dynamic modal predicate calculus. It is argued that a
compositional DRT semantics must employ a semantic type of discourse referents,
as opposed to just a type of individuals. A connection is developed between the
scope effects of epistemic modifiers and the scope-disambiguating effect of "a
certain".Comment: Final pre-publication version, 27 pages, Postscript. Final version

THE INCLUSIVE DYNAMICS OF ISLAMIC UNIVERSALISM: FROM THE VANTAGE POINT OF SAYYID QUTB\u27S CRITICAL PHILOSOPHY
This article pursues a topological reading of Milestones, one of the most influential books in the history of Islamism. Written by Muslim thinker Sayyid Qutb, the general interest in this crucial text has largely remained restricted to the fields of Islamic Studies and Security Studies. This article aims to make the case for assuming a philosophical standpoint, relocating its significance beyond the above-mentioned fields. A creative and topological reading of this text will allow the spatial complexity of Qutbs eschatological vision to be fully exposed, while also unpacking the way in which antagonistic relations have variously been articulated by this thinker. The underlying conviction is that such an examination can offer new perspectives from which to examine and develop current debates on political universalism and antagonism in the tradition of continental philosophy
Perspectives on the Neuroscience of Cognition and Consciousness
The origin and current use of the concepts of computation, representation and information in Neuroscience are examined and conceptual flaws are identified which vitiate their usefulness for addressing problems of the neural basis of Cognition and Consciousness. In contrast, a convergence of views is presented to support the characterization of the Nervous System as a complex dynamical system operating in the metastable regime, and capable of evolving to configurations and transitions in phase space with potential relevance for Cognition and Consciousness
Evaluational adjectives
This paper demarcates a theoretically interesting class of "evaluational adjectives." This class includes predicates expressing various kinds of normative and epistemic evaluation, such as predicates of personal taste, aesthetic adjectives, moral adjectives, and epistemic adjectives, among others. Evaluational adjectives are distinguished, empirically, in exhibiting phenomena such as discourse-oriented use, felicitous embedding under the attitude verb `find', and sorites-susceptibility in the comparative form. A unified degree-based semantics is developed: What distinguishes evaluational adjectives, semantically, is that they denote context-dependent measure functions ("evaluational perspectives")—context-dependent mappings to degrees of taste, beauty, probability, etc., depending on the adjective. This perspective-sensitivity characterizing the class of evaluational adjectives cannot be assimilated to vagueness, sensitivity to an experiencer argument, or multidimensionality; and it cannot be demarcated in terms of pretheoretic notions of subjectivity, common in the literature. I propose that certain diagnostics for "subjective" expressions be analyzed instead in terms of a precisely specified kind of discourse-oriented use of context-sensitive language. I close by applying the account to `find x PRED' ascriptions
On the nature and role of intersubjectivity in communication
We outline a theory of human agency and communication and discuss the role that the capability to share (that is, intersubjectivity) plays in it. All the notions discussed are cast in a mentalistic and radically constructivist framework. We also introduce and discuss the relevant literature
