An influential result of Kant's search was the idea of a "good will" being the only intrinsic good. Moreover, Kant saw a good will as acting in accordance with a moral command, the "Categorical Imperative": "Act according to those maxims that you could will to be universal law." but should not be confused with the Ethic of Reciprocity or Golden Rule, e.g. Mt. 7:12. Whereas the golden rule states that "One should treat others as one would like others to treat oneself," Kant asks us to analyze whether an act can be performed simultaneously by everyone without exception. For example, murder cannot be performed simultaneously by everyone, one set of people would have to live and the other die. That disparity is an exception. The act cannot be performed without exception, therefore it fails the categorical imperative. Contrast this with the golden rule which is subjective to the individual. Following the logic of the golden rule, if I wanted someone to kill me, then it would be acceptable for me to kill others, because I would be doing to others what I would want done to me. This is very important to keep in mind, because Kant's categorical imperative avoids this flaw. From this, and a few other axioms, Kant developed a moral system that would apply to any "praiseworthy person".
