Effective Reasoning (April 17, 2006)

1. Effective Reasoning:Print version

Everyone reasons. Humans are reasoning animals. Further, humans reason with words and symbols.

To reason is to use thought to come to some conclusion. Reasoning can be done alone or in groups.

Unfortunately, being human does not assure any of us that we will reason effectively. In other words, reasoning does not have to produce particularly useful results. Productive reasoning is both an art and a science.

I hope to present here information that will allow most to develop both the skill and the knowledge to reason effectively.

Particularly, I will be discussing informal reasoning. For a complete exposition of effective reasoning, see, also, the Wikibooks Introduction to Moral Reasoning, Formal Logic, and Systems of Logic.
