There is a traditional picture of free speech with which most of us are familiar. On this picture, free speech is a matter of not being prevented from producing meaningful sounds and script (diagrams, etc.), and not being prevented from distributing these sounds and script to the eyes and ears of anyone who cares to listen. Correspondingly, the only or primary duty that goes with free speech is the duty of third parties not to interfere coercively with this process of sound and script production and distribution. In this talk, I argue that there are duties of free speech that go beyond this traditional duty of non-interference with production and distribution: specifically, an imperfect duty of consideration. For what is the point of free speech if ideas are systematically and dogmatically ignored? I explore some practical implications of recognising duties of consideration.
