富勒是繼龐德之後出任哈佛法學院法理學教席的美國法理學家。不過,由於富勒的法理學以人際交往的社會理念作為基礎,雖然發展出眾多發人深省的法律理論,卻始終未能成為法理學研究的重點,甚至逐漸遠離法理學論述的焦點。這個現象在近幾年有了改變,深入探討富勒法理學的論著有增加的趨勢。本文認為,資訊科技所引發的法律典範移轉,似乎也正朝向富勒重視人際交往的法理學轉向。本文以涉及運用點對點傳輸技術侵害數位著作的Grokster案為中心,探討此一問題對法律所構成的挑戰,以及為何我們應當更加正視富勒重視人際交往的法理學,才能找到回應新興資訊科技法律問題之道。
After Roscoe Pound, Lon Fuller held the jurisprudence professorship at Harvard Law School. Fuller's sociological approach emphasizing human interaction is, however, not so welcomed in the jurisprudential world. It is believed that such trend may need a change. This paper discusses the Grosker case first, one that involves digital copyright infringement through the P2P model, and then advocates the need to take Fuller's human interaction conception of law seriously in order to response to the legal challenges brought forward by the information technologies.
