Philosophers who produce ideas about the problem of liberty in general propounded various theories relating to feature, content, and boundaries of freedom. Immanuel Kant is a philosopher who made a name for himself with his thoughts concerning the problem of liberty as well as his ground-breaking ideas in philosophy. The primary purpose of this work is to discuss why he tried to address the freedom in the dual axes in the context of his practical philosophy. Within this framework, it will (...) be scrutinized why Kant founded the liberty by restricting in the philosophy of law while he sought absolute freedom in ethics. (shrink)
