She looked into the distance, and the old terror flamed up for an instant, then sank again. Edna heard her father's voice and her sister Margaret's. She heard the barking of an old dog that was chained to the sycamore tree. The spurs of the cavalry officer clanged as he walked across the porch. There was the hum of bees, and the musky odor of pinks filled the air.

Judge (in the same way as you would judge your own) the behaviour of a dog who has lost his master, who has searched for him in the road barking miserably, who has come back to the house restless and anxious, who has run upstairs and down, from room to room, and who has found the beloved master at last in his study, and then shown his joy by barks, bounds and caresses. There are some barbarians who will take this dog, that so greatly excels man in capacity for friendship, who will nail him to a table, and dissect him alive, in order to show you his veins and nerves. And what you then discover in him are all the same organs of sensation that you have in yourself. Answer me, mechanist, has Nature arranged all the springs of feeling in this animal to the end that he might not feel? Has he nerves that he may be incapable of suffering?

Truth is a good dog; but always beware of barking too close to the heels of an error, lest you get your brains kicked out.

Conscience is the dog that can't bite, but never stops barking.
