"I see so much more than I used to see. The effect has been to depress and sadden and hurt me terribly"

This quote by Zane Grey speaks to the concept of gaining a greater understanding of the world and the people in it. It suggests that with this newly found knowledge comes a sense of sadness and anguish. It implies that the more we learn, the more we understand just how much suffering and oppression exists worldwide. This can be a difficult awareness to come to terms with, and it can be emotionally draining. It is a pointer that knowledge can be a double-edged sword, and that it can bring both joy and discomfort. It is a suggestion to be mindful of the power of knowledge and to use it carefully.
