Reading about nature is fine, but if a person walks in the woods and listens carefully, he can learn more than what is in books, for they speak with the voice of God.
Beauty itself bears witness to God.
Only in space are events and objects and people unique and significant -- and therefore beautiful. A tree has significance if one sees it against the empty face of the sky. A note in music gains significance from silence on either side. A candle flowers in the space of night.
