Abstract
Jeshion (New essays on singular thought, Oxford University Press, Oxford, 2010b) believes that singular thought is implemented by the tokening of mental files (MFC). She also believes that an individual’s being significant to the agent is necessary and sufficient for the agent’s having singular thought about the individual (Cognitivism). Goodman (Rev Philos Psychol 7(2):437–461, 2016a, Philos Q 66:236–260, 2016b) argues that mental files created under a description lead to descriptive not singular thought. She uses this to criticize Cognitivism’s sufficiency claim and MFC. I show that this criticism rests on a faulty conception of the singular thought versus descriptive thought distinction and such files indeed lead to singular thought. This in turn shows that Cognitivism’s necessity claim is false.
