Logic is an essential component both in the history of philosophy and in the understanding of modern philosophical texts. The course “Introduction to Logic” acquaints its students with basic logical tools by locating and assessing valid arguments. Development of the ability to analyze natural language enables exposing language’s logical structures. The first part of the course is devoted to sentential calculus, its semantics and syntax (via Gentzen – style derivation rules). The second part focuses on predicate calculus, ending with relations. The course enables the students to pursue their studies of logic as a field of research as well as providing with the essential tools for reading texts, philosophical and others, through the understanding of the arguments and formulae they present.
