Abstracts

Friederike Moltmann
"The Action-Product Distinction for Transitive Intensional Verbs"
In 1912, Twardowksi introduced a distinction between 'actions' and 'products':
actions (and states) are for example a 'thinking', a 'requesting', and a 'state
of believing', whereas products include a 'thought', a 'request' and a 'belief'.
The two sorts of entities are distinguished in a number of ways: most
importantly only products have truth or more generally satisfaction conditions
and enter similarity relations according to a shared content. In this talk I
explore the way the distinction between actions and products manifests itself
with transitive intensional verbs, such as 'need', 'desire', 'see', and 'buy'.
I argue that the complement of transitive intensional verbs serves not to
characterize a constituent of a cognitive content, but rather the satisfier
(truthmaker) of the product of the action or state the verb describes. Moreover
in general it is possible satisfiers that constitute shared contents of
transitive intensional verbs.

Kevin Mulligan
"Acceptance, Affirmation, Agreement, Acknowledgment, Assertion, Belief,
Certainty, Conviction, Denial, Judgment, Refusal, and Rejection"
Do our doxastic and intellectual states, activities and acts come in polarly
opposed kinds, positive and negative ? I argue that this is, with one
exception, the case. I rely on an account of the category of attitudes put
forward by the earliest phenomenologists rather than the promiscuous and sloppy
category of attitudes popular within analytic philosophy.

Maria van der Schaar
"Wooden Horses and False Friends; a Classification for Non-Attributive Terms"
The paper uses the method of linguistic phenomenology to explain how mere belief
can be elucidated as botched knowing. First, three kinds of non-attributive
terms are distinguished, modifying, privative and restorative terms. It is
shown what the logical properties are of terms like 'fake', 'mere' and 'real',
words that etiolate the meaning of the terms to which they belong, and in what
way Partee (2010), in which it is asserted that these terms behave like
ordinary terms, can be rebutted.

Mark Textor
"Reinach on Rejection and Negation"
The Rejective View of Negation holds that sentential negation is to be explained
on the basis of a prior understanding of the linguistic act or mental act of
rejecting (denying). This act is supposed to be 'on all fours' with assertion
(judgement). In this talk I will develop and defend Reinach's objections
against the assumption of an act of rejection.
