this quote from Lewis Carroll encourages the idea that qualities like craft, ambition, and spite should be subdued or controlled by reason. By doing so, negative or impulsive traits can be transformed into strength. The emphasis is on the power of reason to guide and improve our character, turning weakness into strength.
the phrase suggests that through rational thought, even vulnerable or flawed aspects of ourselves can become sources of greater power. It highlights the importance of wisdom and self-control in personal growth and overcoming challenges.
