Summary and Analysis
Book VI: Chapter X
Understanding and practical wisdom, though different things, operate in the same sphere. Practical wisdom issues commands, since its aim is to tell us what we ought and ought not to do, and understanding passes judgment on these commands. Understanding does not imply either possession or acquisition of practical wisdom. It is also the use of one's faculty of opinion in rightly judging statements made by another person about matters which belong to the realm of practical wisdom.
