How to Think Straight · an Introduction to Critical Reasoning

Practical reasoning and clear thinking are essential for everyone if we are to make sense of the information we receive each day. Being able to quickly know the difference between valid and invalid arguments, the contradictory versus the contrary, vagueness and ambiguity, contradiction and self-contradiction, the truthful and the fallacious, separates clear thinkers from the crowd.

How to Think Straight lays the foundation for critical reasoning by showing many ways in which our thinking goes awry. Celebrated philosopher Antony Flew entertainingly instructs on the many and varied faults that occur in argument, the power of reason, how to challenge assertions and find evidence, and how not to be persuaded by half-truths. Flew also examines poor reasoning, and why we should be concerned with finding the truth.

Lucid, terse, and sensible, with study questions and exercises to help along the way, this enlightening second edition will help you develop the skills necessary to argue and reason effectively by following a few simple, easy-to-remember directions.
