Cactus Language • Preliminaries 2

As a temporary notation, let the relationship between a particular sign and a particular object , namely, the fact that denotes or the fact that is denoted by , be symbolized in one of the following two ways.

Now consider the following paradigm.

In the same vein, if we let the sign “blank” denote the sign “ ” then the string of characters inside the first pair of quotation marks will serve as another name for the string of characters inside the second pair of quotation marks.  In other words, “blank” is a higher order sign whose object is the sign “ ” and the string of five characters inside the first pair of quotation marks is a sign at a higher level of signification than the string of one character inside the second pair of quotation marks.  The relation in question can be abbreviated in either one of the following two ways.

Using the raised dot “∙” as a sign to mark the articulation of a quoted string into a sequence of possibly shorter quoted strings, and thus to mark the concatenation of a sequence of quoted strings into a possibly larger quoted string, one can write the following equation.

The above usage allows us to refer to the blank as a type of character, and also to refer any blank we choose as a token of this type, referring to either in a distinctive way, but without the use of quotation marks.  Since a blank is just what the name “blank” names, it is possible to represent the denotation of the sign “ ” by the name “blank” in the form of an identity between the named objects, as follows.

Given the above identities it is possible to extend the use of the “∙” sign to mark the articulation of either named or quoted strings into both named and quoted strings.  For example, we have the following equations.

Cactus Language • Preliminaries 1

Thus, what looks to us like a sphere of scientific knowledge more accurately should be represented as the inside of a highly irregular and spiky object, like a pincushion or porcupine, with very sharp extensions in certain directions, and virtually no knowledge in immediately adjacent areas.  If our intellectual gaze could shift slightly, it would alter each quill’s direction, and suddenly our entire reality would change.

Picture two different configurations of such an irregular shape, superimposed on each other in space, like a double exposure photograph.  Of the two images, the only part which coincides is the body.  The two different sets of quills stick out into very different regions of space.  The objective reality we see from within the first position, seemingly so full and spherical, actually agrees with the shifted reality only in the body of common knowledge.  In every direction in which we look at all deeply, the realm of discovered scientific truth could be quite different.  Yet in each of those two different situations, we would have thought the world complete, firmly known, and rather round in its penetration of the space of possible knowledge.

Herbert J. Bernstein • “Idols of Modern Science”

The task before us is to describe the syntax of a family of formal languages intended for use as a sentential calculus, and thus interpreted for the purpose of reasoning about propositions and their logical relations.

To carry out our discussion we need a way of referring to signs as if they were objects like any others, in other words, as the sorts of things which can be named, indicated, described, discussed, and renamed if necessary, which can be placed, arranged, and rearranged within a suitable medium of expression — or else manipulated in the mind — which can be articulated and decomposed into their elementary signs, and which can be strung together in sequences to form complex signs.

Signs having signs as their objects are known as “higher order signs”, a topic which demands an adequate level of formalization, but in due time.  The present discussion needs a quicker way to get into the subject, even if it settles for informal means which cannot be rendered absolutely precise.

Another useful viz for tonight's #nhl #hockey game between #Montreal #Canadiens and #Philadelphia #Flyers. It is my rolling #metrics #stats plot, but in comparison mode.

In this case, solid line for #MTL and dashed line for #PHI. Click on legend 2 interact. Each pair of lines are grouped, so clicking on oZS% will show/hide that metric for both MTL and PHI. Rolling mean window is for previous 5 games.
