Our minds are like our stomaches; they are whetted by the change of their food, and variety supplies both with fresh appetite.

Our minds are like our stomaches; they are whetted by the change of their food, and variety supplies both with fresh appetite.

我们的思想就像我们的胃;他们被食物的变化所刺激，而食物的多样性又为他们提供了新鲜的食欲。
