Synopsis
Elements Of Logick, Or, A Summary Of The General Principles And Different Modes Of Reasoning by Levi Hedge is a concise, early 19th?century elementary treatise that presents logic as a practical tool for reasoning in science, history, politics, and daily life. The work opens with an overview of logic’s aims and methods, explaining how terms, propositions, and arguments organize knowledge and guide judgment. It then surveys the leading powers and operations of the mind—perception, consciousness, attention, comparing, abstraction, association, and analysis—before turning to the theory of terms and propositions, including definitions, division, and categories of simple, complex, and modal propositions. The central sections distinguish intuitive and deductive reasoning, explore moral versus demonstrative evidence, and treat induction, analogy, and reasoning on facts. A substantial portion covers syllogistic reasoning (regular and irregular), enthymemes, conditional and disjunctive syllogisms, and sorites, followed by discussions of controversy and interpretation and practical method. Hedge’s volume aims to deliver a clear, accessible foundation of logic for students and educated readers alike.
