Enigmatic "Introductions"

The Trouble Twisters collected three stories about David Falkayn:

in "The Three-Cornered Wheel," Falkayn is an apprentice to a Master Polesotechnician of the Polesotechnic League;

in "A Sun Invisible," Falkayn is a journeyman with Solar Spice & Liquors and the Polesotechnic League factor on the planet, Garstang's;

in "The Trouble Twisters," Falkayn, now a Master Merchant of the Polesotechnic League, leads the first trade pioneer crew for Solar Spice & Liquors.

In the collection, although not in their original magazine appearances, each story is preceded by a peculiar introduction. These introductions make interesting reading but have no bearing on the content of the stories that they "introduce." The three unusual items are entitled:

A Note Of Leitmotif;
Notes Toward A Definition Of Relatedness;
Plus Ca Change, Plus C'Est La Meme Chose -

- and each is either signed by or attributed to a fictional character who makes no other appearance anywhere in the Technic History:

-Vance Hall, Commentaries on the Philosophy of Noah Arkwright;
-Noah Arkwright, An Introduction to Sophontology;
-Recorded in the diary of Urwain the Wide-Faring.

Urwain reminisces about - Noah Arkwright! (Not about David Falkayn.)

In The Technic Civilization Saga, the three items are entitled:

INTRODUCTION THE THREE-CORNERED WHEEL NOTE OF LEITMOTIF;

INTRODUCTION A SUN INVISIBLE NOTES TOWARD A DEFINITION OF RELATEDNESS;

PLUS CA CHANGE PLUS C'EST LA MEME CHOSE.

Thus, readers of the Saga are not informed that "Plus Ca Change..." is meant to introduce "The Trouble Twisters." Instead, they read this strange, short (pp. 77-80; just three pages of text) passage between the van Rijn story, "Territory," and the Falkayn/trader team story, "The Trouble Twisters."
