St. Augustine of Hippo 
Principles of Dialectics [EPUB ebook] 

This work attributed to St. Augustine outlines the foundational concepts of dialectics, focusing on the classification of words and sentences into simple and compound categories. Simple words convey a single meaning, while compound words represent multiple connected ideas. The text further differentiates between simple and compound sentences, emphasizing how they can affirm or deny propositions. It also categorizes compound sentences based on whether they complete a thought or require further context. The discussion culminates in the treatment of matters, words, sayables, and expressions within the framework of logic.
