Kant's Thoughts On Freedom

Kant says, "we could not prove freedom to be something actual in ourselves and in human nature. We saw merely that we must presuppose it if we want to think of a being as rational." Kant also thinks that there is "a sort of circle" in our thinking about the relationship between freedom and morality:" we assume that we are free so that we may think of ourselves as subject to moral laws," and we "think of ourselves as subject to moral laws because we have attributed to ourselves freedom of the will." He then ends with, "Freedom is, therefore, only an idea of reason whose objective reality is in itself questionable."
