Kant's moral philosophy is based on the idea that we should only do something if we would want everyone else to do it too. It's all about being consistent and fair. He calls this the "categorical imperative", which is just a fancy way of saying "do the right thing, no matter what"!
Now, you might be thinking, "But what about situations where there's no clear right or wrong answer?" Well, Kant's got that covered too! He says that we should use our reason to figure out what to do, and to always prioritize the well-being and autonomy of others. It's all about being a critical thinker and making informed decisions.
