Nathan Coppedge, previously the author of the 1-Page-Classics, describes a comprehensive body of techniques advanced enough to yield full-fledged aphorisms of any length and complexity.
This is my excellent treatise on how to write aphorisms, epigrams, etc.
It involves a rigorous categorical method beginning with opposites which may be used to generate flawless word compositions which have coherent relevance.
The section about how to derive translated, more traditional aphorisms is added as a footnote, and is also valuable.
Included is an appendix listing conjunction words and other clarifications about the methodology.
Some of my readers have expressed that they were confused, and didn't understand the writing in this book. The structure of this book is counter-intuitive, and the logic is not the easiest to grasp.
It is a unique 'avant-garde' form of literature, and those with adequate English skills should get something out of it.
I don't promise that you'll love it. But, it has a sincere mission, which is to convey the knowledge of perfect aphorisms to those who are ready to receive it.
