Why does Chapter 17 criticize certain 'learned' individuals, and what does this imply about the nature of true knowledge?

Chapter 17 offers a sharp critique of individuals who are 'learned' in a superficial or scriptural sense but lack true wisdom in their conduct. The text questions the value of such learning if the person still engages in sinful deeds and cannot distinguish right from wrong. It also notes that a person who is always restless, whose heart is unsatisfied, and whose mind is distracted by the greed of the senses will not find peace, regardless of their knowledge. This implies, as per the teachings in Chapter 17, that true knowledge is not merely intellectual accumulation but is integrated with right action, inner tranquility, and detachment from worldly cravings.
