New Series! Shev Shematsa, Part 1, Sha'ar 1, Beginning of Perek 1

From Wikipedia:

Shev Shema'tata (Hebrew: שב שמעתתא), most commonly pronounced Shev Shmaytsa or [1] Shev Shmaisa,[2] is a work on Talmudic logic and methodology by R. Aryeh Leib HaCohen Heller. The name of the book is Aramaic, and means "seven passages".[3]

It consists of seven sections, each with approximately 25 chapters, which explains intricate halakhic topics including the validity of a single witness and the practical ramifications of a doubt. The reasoning process that Heller employs to analyse and resolve these very basic conflicts and contradictions in the Talmud is considered the basis for the analytical method used in modern times in Talmudic study.
