Ethics is knowing the difference between what you have a right to do and what is right to do. Potter Stewart
In law a man is guilty when he violates the rights of others. In ethics he is guilty if he only thinks of doing so. Immanuel Kant
Apart from values and ethics which I have tried to live by, the legacy I would like to leave behind is a very simple one - that I have always stood up for what I consider to be the right thing, and I have tried to be as fair and equitable as I could be. Ratan Tata
A man without ethics is a wild beast loosed upon this world. Albert Camus
The more moral the people are in their business dealings, the less paperwork you need, the more handshakes you can have, the more the wheels of capitalism work better because there's trust in the marketplace. Business ethics is not a joke. And, in fact, I think most businesses that I've dealt with encourage exactly that type of behavior. Rick Santorum
