- Title
Fragile Knowledge.
- Authors
Goldstein, Simon
- Abstract
This paper explores the principle that knowledge is fragile, in that whenever S knows that S doesn't know that S knows that p , S thereby fails to know p. Fragility is motivated by the infelicity of dubious assertions, utterances which assert p while acknowledging higher-order ignorance whether p. Fragility is interestingly weaker than KK, the principle that if S knows p , then S knows that S knows p. Existing theories of knowledge which deny KK by accepting a Margin for Error principle can be conservatively extended with Fragility.
