Author’s Abstract

  1. Today many philosophers of mind accept that the two cortical streams of visual processing in humans can be distinguished in terms of conscious experience.
    1. The ventral stream is thought to produce representations that may become conscious, and
    2. the dorsal stream is thought to handle unconscious vision for action.
  2. Despite a vast literature on the topic of the two streams, there is currently no account of the way in which the relevant empirical evidence could fit with basic Husserlian phenomenology of vision.
  3. Here I offer such an account. In this article I show how the empirical evidence ought to be understood in a way that is informed by phenomenology. The differences in the two streams are better described as differences in spatial and temporal processing.
  4. Rather than simply 'unconscious,' the dorsal stream can be better described as making a special contribution to what Husserl identified as the visual horizon.
