Abstract
A common and popular option in defending Physicalism against the Knowledge Argument is the “phenomenal concept strategy” . PCS claims that, although ex hypothesi Mary knows all the propositions pertaining to color and experiences of color, there is at least space for the claim that she acquires a new concept, and thereby accesses these propositions under different, phenomenal modes of presentation. In short, Mary acquires new concepts upon her release and that explains her “discovery.” Here I will show there is a way of saving Physicalism that does not appeal to PCS in the standard sense but entails that Mary acquires the ability to think a new kind of singular thought. In acquiring this, she gains a kind of indexical, egocentric knowledge
