In biblical wisdom literature, the opposite of a wise person is called a fool.
In Proverbs 8 and 9, Solomon personifies wisdom and foolishness as two women. Wisdom is a woman who leads her followers to God and life. Her ways have more value than any amount of physical wealth. On the other hand, the foolish woman leads her followers to death.
The book of Proverbs is filled with explanations of the differences in character, behavior and results of a life based on wisdom versus one based on folly.

Solomon concludes that a foolish person is self-centered, arrogant and controlled by his or her own emotions. The fool is unable to accept correction from others and refuses to accept responsibility for the consequences of decisions, but instead blames God. The result is a lifestyle based on self-ordained concepts of right and wrong instead of obedience to God; seeking of immediate physical pleasure instead of building personal character; repetition of mistakes; restless wandering void of peace; and relationships filled with strife.
1. Wisdom is something to be pursued because it contains more value than gold or precious stones.
2. Copy proverbs and wise sayings into a small book and review them daily.
3. When you read a proverb take a few minutes to consider how the principle can be applied to everyday life.
