The fool’s life is run by his desires and fears. This is what you hear from your young children. The most common phrases in the vocabulary of a 3-year-old are, “I want … ” or “I don’t want … ” The fool lives out of the immediacy of his lusts, cravings, expectations, hopes, and fears.
This is not totally true. A 3-year-old child doesn't always want or not want something because he is a fool living out of the "immediacy of his lusts, craving, expectations, hopes, and fears." Some of it is because he's a human who had needs. He will articulate this in the best way he knows how. What parents might interpret as utter selfishness may not be at all what is going on. There is an age appropriate developmental thing going on that ought not to be identified with sinful selfishness of a a fool.
