Special Issue of Studia Logica on Truth Values

Guest editors: Yaroslav Shramko and Heinrich Wansing

Deadline for submission of manuscripts: October 31st, 2008.

The notion of a truth value is among the most important notions of
modern symbolic logic and analytic philosophy. It has been explicitly
introduced by Gottlob Frege who considered exactly two classical truth
values - the True (das Wahre) and the False (das Falsche), which played
in his theory the role of references (Bedeutungen) for sentences. In
this connection Frege characterized logic as the discipline that should
investigate the "most general laws of being true". Another prominent
supporter of this view was Jan Lukasiewicz, who explicitly defined
logic as the science of truth values.

In modern logic there is an influential tradition of representing
logical calculi as systems of truth values (valuational systems). On
can mention in this respect Lukasiewicz, Alfred Tarski, and other
representatives of the "Polish School". There are several possible ways
to generalize the notion of a classical valuational system introduced
by Frege. In the literature one can find, for instance, conceptions of
constructive versus non-constructive truth and falsity. Moreover, the
information human and artificial agents are confronted with is often
incomplete and sometimes inconsistent, suggesting that statements may
also be evaluated as neither true nor false or both true and false.
Thus one arrives at the idea of many-valued logics, partial logics,
paraconsistent logics, etc. which are heavily oriented towards possible
applications in epistemology, AI and computational linguistic.

Truth and falsity may receive other philosophically relevant
qualifications: necessary truth, possible falsity, truth henceforth,
commonly known truth, truth by default etc. Classical and non-classical
truth values may be combined to obtain new, structured truth values.
The idea of generalized, possibly structured truth values suggests
ordering relations on these values. The values may be compared with
respect to their degree of constructiveness, necessity, amount of
information they give, etc. As a result, one obtains lattice structures
of generalized truth values (more specifically - structures known as
bilattices, trilattices and, more generally, multilattices). Natural
algebraic operations on these lattices correspond to logical
operations, and the ordering relations give rise to entailment
relations.

The purpose of this special issue of Studia Logica is to concentrate on
various interrelated aspects of truth-values: philosophical, logical
and algebraic among them. We invite papers which

- philosophically elucidate and theoretically explicate the notion of a
truth value;
- elaborate general formal tools for a uniform treatment of various
logical, mathematical and philosophical aspects of truth values and
valuational systems within a joint theoretical framework;
- interpret various logical calculi as valuational systems, develop
general methods of formalizing (in axiomatic, sequent, tableau etc.
style) logical theories on the basis of a given system of truth values
and examine their syntactic and semantic properties;
- investigate topical problems of many-valued logics, such as Suszko's
Thesis, truth value gaps, logical and semantic paradoxes etc.;
- consider possible applications of generalized truth values and
generalized truth value functions in various areas of philosophical and
mathematical interest.

There will be a workshop devoted to the same topic. Selected papers
from this workshop will be considered for inclusion in the special
issue.

Submission of Papers

Submitted papers should not exceed 20 pages (including bibliography),
and should be formatted according to the Studia Logica LaTeX style (see
Information for Authors). Only electronic submissions will be accepted.
The authors should send an email with subject "Studia Logica
Submission" to the guest editors (Yaroslav Shramko, yshramko@ukrpost.ua
and  Heinrich Wansing, Heinrich.Wansing@tu-dresden.de), with the file
of the paper as an attachment ("tex" and "pdf" files), and the
following information in the body of the email in plain text: paper
title, author names, surface mail, email address and phone number of
the contact author and a short abstract.

Deadline for submission of manuscripts: October 31st, 2008.

All papers will be refereed according to the standards of the journal.
The refereeing process is expected to be finished by the early spring
of 2009 and the issue published summer/autumn 2009.
