“A sound heart is a surer guide than an ill-trained conscience.”

“I have found out that there ain't no surer way to find out whether you like people or hate them than to travel with them.”

“it don’t make no diference whether you do right or wrong, a person’s conscience ain’t got no sense, and just goes for him anyway. If I had a yaller dog that didn’t know no more than a person’s conscience does I would pison him. It takes up more room than all the rest of a person’s insides, and yet ain’t no good, nohow.”

“A clear conscience is the sure sign of a bad memory.”

“Good friends, good books, and a sleepy conscience: this is the ideal life.”

“The truth is, a person's memory has no more sense that his conscience, and no appreciation whatever of values and proportions.”

“When ill luck begins, it does not come in sprinkles, but in showers.”
