Apart from these criteria it is common knowledge that it is right not to harm anyone and wrong to do harm. It is right to see good in others and wrong to see bad in anyone. It is right to love people and wrong to hate them. It is right to admire men for the good in them and wrong to rebuke them for their shortcomings and bad behaviour. It is right to give advice to a man if he is doing wrong and wrong not to advise him to do good. It is right to do things which will be helpful to oneself and others and it is wrong to do things which will harm others. It is right to speak the truth but wrong to speak words that will harm others even if they are the truth. It is right to be good to others and wrong to be unpleasant to anyone….
