Kantianism is a type of ethical theory created by a philosopher named Immanuel Kant. It is about doing the right thing even if it is hard or uncomfortable. Kant taught that people should never treat others as a means to their own ends. He said that people should always act in a way that respects the dignity of others. Kant believed that people should have an inner sense of morality that guides them to make the right decisions, rather than just following prescribed rules. He also believed that people should use reason and logic to guide their decisions and never act based solely on their own desires. Kantianism also emphasizes the importance of being honest and treating others with respect.
