This quote emphasizes the virtue of moderation and balance in life. It suggests that the person who truly knows how to live is the one who can maintain a middle ground, not leaning too heavily on one side or the other. This could be interpreted in many ways, such as not indulging in extreme behaviors or emotions, not taking sides in conflicts without considering all perspectives, or not relying too heavily on either logic or emotion but using both in balance. The ‘middle state’ signifies a harmonious and balanced approach to life, which is often seen as the key to happiness and success.

In today’s world, this idea is incredibly relevant. We often see polarized views on politics, religion, and social issues where people lean heavily on one side or the other, often leading to conflict and division. By maintaining a middle state, one can understand and respect differing perspectives, promoting peace and unity.

In terms of personal development, the concept of balance is fundamental. It’s about balancing work and leisure, socializing and solitude, ambition and contentment. Leaning too heavily on one side can lead to stress, burnout, loneliness, or dissatisfaction. By keeping a middle state, one can pursue personal growth while also maintaining mental and emotional health.

Furthermore, this quote can also be related to the idea of resilience. Life will inevitably bring challenges and setbacks. The individual who can maintain a middle state, not becoming too despondent in the face of adversity nor overly complacent in times of success, is more likely to navigate these challenges effectively and bounce back from them stronger.

In conclusion, this quote is a call for balance, moderation, and resilience – qualities that are as important today as they were in Pope’s time.
