Ethics is patience. Ethics is kind. Ethics always perseveres. Ethics never fails. Differentiate between ethics and justice.
Ethics means staying at the university late, without pay, to help students.
Ethics are necessary for a human system to work. Differentiate love from loving, e.g. falling in love. Ethical love remains, regardless of notions. May love the dog, but if we have to walk it every day, psychic love may disappear, but will continue to walk the dog. Ethical love is true in long marriages, where we stay true to the promise.
