 Shepherd’s two longer essays develop a doctrine of cause and effect and the beliefs it underwrites. The shorter essays collected in Shepherd’s second volume range over related specific topics including: Berkeley’s philosophy, the co-incidence of extension and color, the credibility of miracles, nature of final cause, and the reason of single erect vision. In addition to works mentioned above, there are three published works of Shepherd: critical remarks on the metaphysics of John Fearn, a retired naval officer (Shepherd 1832); a very effective reply to Fearn’s counter-critique of her metaphysics; and an article on the single and erect object of vision (Shepherd 1827b). In the present article, we will focus on her two main philosophical works but consider some directly relevant material from the shorter essays.
