Logic

Logic is the branch of philosophy dealing with arguments.

Branches of Logic[edit]

Logic is divided into two main branches: inductive and deductive logic.

Review[edit]

Terms:

  • Axiomatic System- a deductive system of reasoning that starts with a relatively small number of basic principles (axioms).
  • Predicate Logic- the branch of symbolic logic that takes predicates as the fundamental units of analysis.
  • Sentential Logic- the branch of symbolic logic that takes sentences as the fundamental units of analysis.
  • Truth Preservation- the inability of a method or pattern of reasoning to take one from truths to falsehood.
