What of these other fours?
 Post appears BELOW Table of Contents.
 This blog focuses on similarities between others' four-folds, tetrads, tetrachotomies, and mine, and includes links to online information on others’ fours in their own terms. It results from overgrowth of an old post at The Tetrast "What of these other fours?".

Popper, McLuhan, Fuller, Kant, Heidegger
What would those five names be doing in one post? Nothing much. Each of the five cases involves a fourfold for which I see no strong correlation to my fourfolds.

Karl Popper's tetrad — (a sequential tetrachotomy? or a genuine tetrad? of) problem, tentative theory, (attempted) error-elimination (especially by way of critical discussion), new problem(s): “P 1 » TT » EE » P2 . ” I’ve tried but haven’t yet found a correlation. I can see that it could be argued that it’s a triad beginning to cycle.

Marshall McLuhan's tetrad — a tetrachotomy of enhancement, erosion, retrieval, reversal — I’ve tried but haven’t yet found a correlation.

Buckminster Fuller's tetrahedra — are not about specific foursomes of philosophically relevant conceptions, as far as I’ve been able to tell.

KANT'S TABLE OF CATEGORIES
1 of Quantity:
Unity
plurality
totality


2 Quality
Reality
Negation
Limitation
3 Relation
Substance and accident 
Cause and effect 
Action and reaction 
 

4 Modality
Possibility -- Impossibility
Existence -- Non-existence
Necessity -- Contingency
TETRASTIC CATEGORIES (mine)
Correspondence /
variance
(another than,
double of, sum of,
antiderivative of, etc.).

Mode of
attributability
(indeed, not, if, possibly,
novelly, probably,
optimally, feasibly, etc.).
И
Modification,
attribute, accident
(firm, unsound, well, ill,
steady, irregular,
strong, weak, etc.).

Substance,
hypostasis
(this man,
this horse,
etc.).
Kant's basic four categories -- quantity, quality, relation, modality. I don't see any special resemblance to my fours.

Martin Heidegger's fourfold — earth, sky, mortals, and divinities — I’ve tried but haven’t yet found a correlation or even a way to understand it. In "The Restriction of Being" in Introduction to Metaphysics, Heidegger discusses a four-way restriction or delimitation of Being by things which aren't non-being but which are nevertheless seen in oppositions to Being. I don't see a correlation there either.
the ought
↑
becoming ← Being → seeming  
↕
thinking
(In Heideggers's diagram the reader sees "the ought" above an upward arrow rising from "Being"; from "Being" an arrow points leftward to "becoming"; from "Being" an arrow points rightward to "seeming"; and beneath "Being" the reader sees "thinking" and a two-way vertical arrow both up and down between them.)


Update: Here's my vent anent Popper's use of the words "verification" and "falsification." - posted by The Tetrast @ 10:08 PM [top of post] [top of page] Copyright © BenjaminðA.ðUde11.
