Is JTB Knowledge Hopeless?

An argument structure that covers both cases Gettier described in his 1963 paper reinforces the conclusion of my 2012 Logos & Episteme article that the justified true belief (JTB) conception of knowledge is inconsistent. The stronger argument makes possible identification of fundamental flaws in the standard approach of adding a fourth condition to JTB, so that a new kind of skepticism becomes inevitable unless conceptual change occurs.
