4.五色令人目盲；五音令人耳聋；五味令人口爽；驰骋田猎，令人心发狂；难得之货，令人行妨。（卷三十四 老子）
【白话】贪恋五花八门的色彩，使人精气神外散，视觉迟钝；过度追求音乐的刺激，使人心中失去平和中正之气，听觉迟钝；讲究食物的美味，使人味觉迟钝；沉溺于骑马打猎的快意，使人心神狂妄暴躁；稀有难得的货品，会使人贪心增长，而造成行为偏差。
Craving for visual splendor can distort our vision and impede our ability to see the truth about things. Basking in musical amusement can numb our hearing and impede our ability to appreciate the finer meanings in music. Excessive indulgence in fine cuisine can dull our taste buds and impede our ability to appreciate the food. Wallowing in the thrill of game hunting can make us reckless and lose our sanity. Being desirous of rare and precious objects can cause our greediness to grow and drive us to behave wickedly.
