Cactus Language • Pragmatics 6

It is possible to trace the divergence of formal grammar styles to an even more primitive division, distinguishing between the additive or parallel styles and the multiplicative or serial styles.  The issue is somewhat confused by the fact that an … Continue reading

Cactus Language • Pragmatics 5

Along with the distinctions we see evolving among different styles of grammar and the preferences different observers display toward them, there naturally arises the question:  What is the root of that evolution? One dimension of variation in formal grammar style … Continue reading

Cactus Language • Pragmatics 4

The questions about boundary conditions we keep encountering betray a more general issue.  Already by this point in the discussion the limits of a purely syntactic approach to language are becoming visible.  It is not that one cannot go a … Continue reading

Cactus Language • Pragmatics 3

Having broached the distinction between objective propositions and syntactic sentences, its analogy to the distinction between numbers and numerals becomes clear.  What are the implications of that distinction for the realm of reasoning about propositions and its representation in sentential … Continue reading

Cactus Language • Pragmatics 2

The pragmatic theory of sign relations is called for in settings where everything that can be named has any number of other names, that is to say, the usual case.  Of course we’d like to replace the multiplicity of signs … Continue reading

Cactus Language • Pragmatics 1

Expanding our perspective on the options for formal grammar style brings us to questions about the manner in which the abstract theory of formal languages and the pragmatic theory of sign relations interact with each other. Formal language theory can … Continue reading

Cactus Language • Stylistics 6

Perhaps I ought to comment on the differences between the present and the standard definition of a formal grammar, since I am attempting to strike a compromise with several alternative conventions of usage, and thus to leave certain options open … Continue reading

Cactus Language • Stylistics 5

Before the capacity of a language to describe itself can be evaluated, the missing link to meaning must be supplied for each of its expressions.  That means opening a dimension of semantics to be navigated by means of interpretation, topics … Continue reading

Cactus Language • Stylistics 4

The present patch of discussion is concerned with describing a family of formal languages whose typical representative is the painted cactus language   Once we have the abstract forms of cactus languages well enough in hand to grasp their application, … Continue reading

Cactus Language • Stylistics 3

As a rough illustration of the difference between rhetorical and logical orders, consider the contrasting types of order appearing in the following conjunction of conditionals. The formula exhibits a happy conformity between its rhetorical form and its logical content, in … Continue reading
