Subtitle: logic ..
Description: From the author's introduction (italics his):
"Truth is the object of thinking.  Some truths are obvious; others are difficult of attainment.  Correct thinking is a prime necessity in the solution of complicated problems, and logic enables us to think correctly.  Logic *is the science of those principles, laws and methods which the mind of man in its thinking must follow for the accurate and secure attainment of truth*.

Ordinary man has natural logic or common sense.  *Scientific* logic is natural logic trained and developed to expertness.  Logic as a *science* consists of a comprehensive body of established principles and laws with their legitimate conclusions; logic as an *art* is the mastery if the technique embodied in these principles and laws.

*Ideas, judgments, and inferences* are the elements which enter into the operations of the mind in its attainment of truth.  Scientific *methods* are also of importance for this purpose.  Hence, logic will treat of ideas, judgments, deductive and inductive inferences. "
