We might think that there is a simple and straightforward solution to the Gettier problem. Note that my reasoning was tacitly based on my belief that the clock is working properly, and that this belief is false. This seems to explain what has gone wrong in this example. Accordingly, we might revise our analysis of knowledge by insisting that to constitute knowledge, a belief must be true and justified and must be formed without relying on any false beliefs. In other words, we might say, justification, truth, and belief are all necessary for knowledge, but they are not jointly sufficient for knowledge; there is a fourth condition – namely, that no false beliefs be essentially involved in the reasoning that led to the belief – which is also necessary.
When we talk about emotional expression in ordinary interaction, what typically comes to mind is showing what you’re feeling. To express emotions often means to give a “read out” of the heart. This was in no small part the mission of modern dance. “To make visible the interior landscape,” was how Martha Graham described the modernists’ reaction to the mannerism of ballet. But expression as showing what you’re feeling is far too narrow a view of the presentation of emotion in both ordinary interactions and performative space. Thinking about modern dance as a reaction to ballet, and ballet and its commingled roots in court etiquette and military drill sheds light on a broader view of emotion expression as communicative and the critical role of dynamic movement of the body proper in that expression.
