Propositional Structure and Propositional Implication

1982
In this chapter we deepen our characterization of propositions and study the basic structures of propositional implication. Here is, then, a short, but slightly unconventional (because more philosophical), introduction to standard two-valued logic. We need this introduction, not only for completeness, given that propositions are contents of practical ...

Proposition of Two Cipher Structures

2010
In this paper, we have proposed two block cipher structures which can be considered as variants of SP-network and Generalized Feistel structure respectively. Our main idea is to improve the diffusion effect when mixing all the sub-blocks together in each round.

Propositions, Structure and Representation

Proceedings of the Aristotelian Society (Hardback), 2012
Neo-Russellian theories of structured propositions face challenges to do with both representation and structure which are sometimes called the problem of unity and the Benacerraf problem. In Si, I set out the problems and Jeffrey King's solution, which I take to be the best of its type, as well as an unfortunate consequence for that solution ...

What propositional structure could not be

Synthese, 2017
The dominant account of propositions holds that they are structured entities that have, as constituents, the semantic values of the constituents of the sentences that express them. Since such theories hold that propositions are structured, in some sense, like the sentences that express them, they must provide an answer to what I will call Soames ...

Compositionality and Structured Propositions

Thought: A Journal of Philosophy, 2013
In this article, we evaluate the Compositionality Argument for structured propositions. This argument hinges on two seemingly innocuous and widely accepted premises: the Principle of Semantic Compositionality and Propositionalism (the thesis that sentential semantic values are propositions).

A Theory of Structured Propositions

Philosophical Review, 2023
This paper argues that the theory of structured propositions is not undermined by the Russell-Myhill paradox. I develop a theory of structured propositions in which the Russell-Myhill paradox doesn’t arise: the theory does not involve ramification or compromises to the underlying logic, but rather rejects common assumptions, encoded in the notation of ...

Why the tuple theory of structured propositions isn't a theory of structured propositions

Philosophia, 2003
Much is at stake. The notion of structured propositions – in particular structured singular propositions – is a cornerstone of the theory of direct reference, yet if the intuitive notion of structured proposition cannot possibly translate into ordered ntuples, as direct reference theory does, then that theory finds itself without a semantics in one of ...

The Structure of the Proposition and the Fact

Philosophy of Science, 1936
For the most part, this paper is an attempt to understand such a statement as this: “The proposition represents the fact by virtue of a structural identity between it and the fact.” The statement is a familiar and important one in modern philosophy. It is, for example, one of the tenets of Logical Positivism.
