Henry David Thoreau Quote
The natural historian is not a fisherman who prays for cloudy days and good luck merely; but as fishing has been styled "a contemplative man's recreation," introducing him profitably to woods and water, so the fruit of the naturalist's observations is not in new genera or species, but in new contemplations still, and science is only a more contemplative man's recreation.
