Ethics is the branch of philosophy that deals with moral principles and values. It involves examining the concepts of right and wrong, good and bad, and individuals' obligations towards one another. Ethical practice refers to applying these principles and values in various contexts, such as business and education. It involves making decisions and taking actions consistent with ethical standards and principles. Ethical theories are frameworks that provide a systematic way of thinking about ethical issues. These theories help us understand the nature of ethical concepts and guide how to make ethical decisions. Some examples of ethical theories include consequentialism, deontology, and virtue ethics.
