George Berkeley’s Embodied Vision

What is it about?

Taking up John of Salisbury’s dictum that we read ancient texts to improve our eyesight, this article returns to an “old” book for “new” insight into the perennial philosophical problem of visual perception. A careful reading of Berkeley’s essay on vision improves our eyesight in at least four ways: First, it reminds us that the most interesting aspects of visual perception are not “primary” but “derivative.” Second, it reminds us that our relationship with the world is an interactive process of making connections and proposes some ways in which those connections and the process of making them might be brought to consciousness and subjected to critical examination. Third, it reminds us of the extent to which making connections is a linguistic process: we live in language as surely as we live in the world, and the processes by which we take our places in the world are forms of language. Fourth, it introduces a concept of “levels” and movement between them that is particularly important to computational models that may result in nonhuman analogues of human vision.
