I will briefly comment upon how the first 26 of these are related or relevant to, or different from, the subdivision PATHS.

1st. COURSES: The main difference is that whereas these tend to be temporal, paths tend to be spatial; or if both are spatiotemporal phenomena, then this is what they usually emphasize, respectively .

2nd. NEXUSES These are links or connections between things; usually larger or more complex, and refer explicitly or implicitly to some actual or potential movement, transport, or transmission along themselves. Nexuses are more comprehensive and diverse; their nature less definite.

3rd. TREES: Most paths do not branch, but often anastomose when they do. Usually a tree is just a particular structure.

4th. THALWEGS: These are paths, or at least things with which paths may be associated; but they are more specialized. The actual or virtual spatial dimensionality is higher. the thalweg has an average, negative, and abstract quality.

5th. SHORTCUTS: Analogs of thalwegs, these are types of paths; a large fraction of paths are in some sense shortcuts.

6th. SEQUENCES: Usually these are less spatial or more abstract than paths, and they are more apt to be chainlike or to consist of discrete parts in mathematical order or proportion.

7th. FLOWS: Here the thing is the flow, whereas a thing follows or describe, a Path; flows are massive and usually two- or three dimensional of themselves, Flows are more apt to follow paths than paths flows. The flow is usually a process, the path a thing or locus; a flow is more apt to be a complex phenomenon, with properties like elasticity, nonlinearity, turbulence, or dimensionless numbers.

8th. CHAINS OF CONSEQUENCES: Usually these are sequences restricted to casual effects or casual corollaries; the expression may be over actual or abstract space. Paths may take this form, or be so represented; types of paths may partly or wholly correspond to or be illuminated by types of chains of consequences.

9th. MOTIONS: These may or may not be path-like, in the usual sense, but they can describe what passes over or makes a path, or the process thereof, as well as the things or processes that a path may be perturbed by; and motions may arise from, reflect, or be regulated by paths-and types, aspects, and laws thereof.

10th. SERIES: More protean and recursive, generally, than a sequence or path, these may nonetheless be what underlies the continuity of a path, or its continuous generation.

1lth. STORIES: The progression of a path may tell a story, and the unfolding of a 'story' (in the ideonomic sense) may be described with the help of a path.

12th. HISTORIES: The same is true here, and histories may have their paths graphed.

13th. NETWORKS: Path will often give rise to lateral branches, to cross-hatching with parallel paths (themselves perhaps induced), to anastomoses, and to backward and return branches; resulting in the formation of networks. Preexisting networks may channel the paths taken by things; and they may induce the growth of new paths and the extension of old ones.

14th. ALTERNATIVE HISTORIES: The study of the range of known and possible structures of paths can aid visualization of other courses the histories of things might have taken.

15th, GOALS: Paths can suggest what goals are attainable or how to attain those goals.

16th. ORIGINS: The origin of a thing may be discovered by reconstructing its path backwards from the present or forwards from the past, or by noting the convergence or divergence of many paths, backwards or forwards in time.

17th. CONVERGENCES: Different convergences upon an identical goal imply different paths; and vice versa, The paths of many things coming together may influence and shape one another, The study of convergences in general can create insights about how, where, when, or why things may or must end.

18th. DIVERGENCES: The way in which things diverge from their origins can help one to deduce their subsequent paths. The analysis of divergent paths provides a wealth of insights into the nature of phenomena.

19th. ALTERNATIVES: A path is like a sequence of choices over a set of alternatives.

20th. MORPHOLOGY: The science of form is the science of forms that paths may and must have. It is also the science that can translate the significance of the forms that paths exhibit.

21st. ENVIRONMENTS: Different environments (different in type, content, processes, forces, &vc) give rise to different paths; like paths may arise in like environments, in connection with like and unlike things, or the last may give rise to unlike paths in these same environments and the reasons and laws for all of these things, once worked out, may at once illuminate the environments, paths, and things. Environments that are the matrices of paths are effectively but an everted, inverted, or negative form of these same paths; paths and their environments form systems of enantiomorphs, which the limitations and biases of human perception and cognition determinedly and consequentially mask.

22nd. DOMAINS: The vast anatomy of the universe is areolated into multitudinous contiguous, interpenetrating, and overlapping domains, within, between, and among which paths form the circulatory system-an illimitable web of routes, connections, flows, and exchanges. These domains have their characteristic properties, and that which has just been said about environments applies equally to domains.

23rd. BEHAVIORS: The various and characteristic types of behavior that things exhibit determines-and can be used to describe and predict-their paths; likewise the laws that produce this behavior can be used to clarify the corresponding, and more general, laws of paths.

24th. DEGREES OF FREEDOM: If one is to master a path it is almost critical for one to know the degrees of freedom of the path and of whatever it is that is imagined as traversing the path, and this knowledge should at least include the number, quality, range, source, orientation, rules, and interrelationship of these degrees of freedom.

25th. MECHANISMS: The path in space and time by which food traverses the alimentary canal depends upon the complex mechanisms that govern digestion and the motility of the digestive track (peristalsis, churning, absorption, irrigation, acidification, valvular function, neural programming and interaction, and so forth). In a sense the path is indescribable and incomprehensible without reference to the lawful interplay of this environmental machinery. Yet the machinery of environments is ideonomically generalizable.

26th. CAUSES: The path of a hemline and the path of, say, a foraging butterfly can share the same generic causes.- placation (of cloth and wind billows or currents alike), alternating helical twisting and counter-twisting (of hemline and fingers of air alike), natural selection of 'safe' flutter (of the feminine hemline before male eyes, and of the butterfly passing before the eyes of numberless potential predators), universal neuromuscular curves (shaping the movements of hungry butterflies and busy seamstresses since time immemorial by an identical mathematical function), etc.

Once ideonomy has developed into a mature science, and the methods and materials of its manifold subdivisions exist, the treatment of things in terms of their paths will benefit immensely from consultation with the many subdivisions that have just been considered. But for the moment, both the reader and the writer must use their imaginations.
