Through a variety of logical/linguistic investigations, the past century
witnessed some of the most important advances in the history of philosophy.
The outcome, however, has been the largely isolated results of a piece-meal
approach to philosophy. In his landmark work Sign Levels, D.S. Clarke
provides readers with an integrative framework designed to overcome this
lack of sustained focus. Drawing on the pragmatist tradition of semiotic of
Peirce and Morris, he traces the development of the logical categories of
language to the more primitive sign levels of natural events and signals.
The concluding chapters discuss the unique features introduced by spoken
natural languages and the written specialized languages used within social
This bold venture into synthetic philosophy provides:
* a methodology for comparing language to primitive sign levels that avoids
* comparisons and contrasts between sign levels that enable distinctions
between necessary and contingent features of language;
* an integrative framework for relating isolated results in linguistic
philosophy, experimental psychology, and ethology;
* a means of resolving some of the principal metaphysical disputes derived
from linguistic investigations.
