Kant’s practical philosophy has two ideals, but Kant seems mostly silent on the connection between them: namely the Just State and the Kingdom of Ends. Religion within the Bounds of Mere Reason certainly gives a semblance of an answer, in claiming that we, as a community of humans, require the Just State in order to bring about (or ‘think of ourselves as in’) the Kingdom of Ends. However, Kant seems to also make it clear that every individual is capable of ethical reasoning prior to the civil condition (i.e., prior to the Just State). I argue that ethics is necessary for right, and thus that right is sufficient for ethics. The necessity of ethics is found in the creation of the Just State to begin with (and thus the system of right, itself, cannot exist without the pre-existing ethical faculty). The sufficiency of right is discovered through a kind of practice of the use of our practical reasoning (which I call ‘practical practice’) through balancing the important tension between cosmopolitan right and civil right, such that we become better at balancing an analogous tension between love and respect. Thus, in this dissertation, I argue that our individual attempt to achieve the Just State is sufficient (but not necessary) for considering ourselves self-legislating members of the Kingdom of Ends.
