法律哲学如何才能成为一门法律科学?在米歇尔·托贝看来,凯尔森的理论并不是法律科学,因为,纯粹法学理论是以规范为对象的,而规范作为价值却不可能成为科学的对象。托贝从现实主义的视角认为,立法者所制定的只是文本,而非规范;而文本只有经过法官解释后,才成为了规范。因此,托贝将规范还原为事实,从而将法律哲学建构成为以事实为对象的法律科学。 How can legal philosophy become a science of law? According to Michel Topois, Kelsen’s theory is not legal science, for pure jurisprudence is based on norms and norms can not become value Scientific object. From the perspective of realism, Toby argues that legislators only make texts, not norm, and texts become norm only after the judge interprets them. Therefore, Toby restored the norm to the facts, so as to construct legal philosophy as the legal science which is based on facts.
