Ethical decision making and critical thinking are important topics in our society, because the more people think about good decisions and ethics, the better our society will be.
Critical thinking and ethics are related in many ways. Let me explain. To make an ethical decision means that a person has thought about the rightness or wrongness of a decision and a manner of life and committed to live well. This act of decision making requires reflection or we can say critical thinking.
Critical thinking, from this perspective, is to choose the most ethical path given the myriad of possible choices.
