NOTES
1 There is disagreement among philosophers about whether reasoning takes place directly
in language, or indirectly in the concepts that are expressed through language. For the
purposes of this book, I will take the second position. Of course, if an argument is well
written, then the indirect structure should be very clear. However, such clarity is rare in
most commonplace language.
2 While I focus on analysis in this book, I do not wish to understate the importance of
clear written expression. For more information, consult any of the many good books on
written communication that are available.
3 The casting method is commonly used in reasoning textbooks. It was developed princi-
pally by Michael Scriven. For an excellent, in-depth look at casting, see J. Rudinow and
