Abstract
Examining Scepticism and Animal Faith (SAF) together with the work of Descartes—first, in terms of structure, style, and substance; and second, in terms of method and purpose—supports a rethinking of Santayana’s philosophical project, supporting the notion that his primary aim was not epistemological but fundamentally moral. Considering the contrasting characters of Cartesian and Santayanan scepticism suggests that Descartes is not so much a foil but an inspiration for Santayana in attempting to order the mind as a sort of personal improvement.
