Synopsis
Like personal trainers, the Workbooks offer a practical and empathic approach to introductory logic. They are designed for beginners and for anyone who wants to build confidence by doing more exercises. Workbook 2 helps you learn how to:
- do truth-value calculations by means of a step-by-step method
- construct a truth table for a group of arbitrarily complex propositional forms
- use the truth-table method to determine the applicability of the following concepts:
- tautology, contradiction, and contingency
- validity
- logical equivalence, logical implication, and logical consistency.
There are numerous
exercises whose
difficulty increases gradually. The point is to train your "logic muscles" until they become strong enough to carry "heavy-weight" content. The study is aided by many examples worked out
step by step, warnings of
common errors, as well as
complete solutions to all exercises.
There is another edition (Full Edition) of Workbook 2. The
Full Edition has a supplementary unit on the
indirect truth-table method. The supplementary unit on the indirect truth-table method is also available as Logic Self-Taught Workbooklet 2.A.
Logic Self-Taught Workbooks are based on the insight that
understanding logic is
not sufficient for learning logic, just as understanding how to swim is not sufficient for
learning to swim and understanding the grammar of a foreign language is not sufficient for
learning the language. You need to
practice and take
an
active part in
self-teaching. Through
systematic work with the Workbooks, you will build
self-confidence.
You can
learn logic, even its hardest parts.
