Abstract

In The Transmission of Knowledge (2021), Greco departs significantly from his earlier view of all knowledge as an individual achievement of the knower, allowing that in some testimonial knowledge cases (cases of “transmission”), a hearer’s believing truly will be due to competent joint agency, between herself and the speaker. Greco argues that the new, hybrid view of knowledge as individual or joint achievement is still sufficiently unified and – importantly – still provides a satisfying answer to the value problem for knowledge. I will raise some worries for this latter claim. I begin by raising worries about Greco’s earlier answer to the value problem: that knowledge is distinctively valuable as an (individual’s) achievement. I then argue that these worries are not allayed by expanding the account of knowledge to include joint achievements and indeed are perhaps aggravated by this new move.
