    We perceive motion directly rather than inferring it from memory of past positions.

    Reasons For

    1 perspective
    Reason for
    ?
    • 1.Seeing a second-hand move is qualitatively different from 'seeing' that an hour-hand has moved.
      ?

      Think about whether this reason is strong or weak

    • 2.When watching a second-hand, we do not see its current position and recall its earlier position; we simply see the motion itself.
      ?

      Think about whether this reason is strong or weak

    Reasons Against

    2 perspectives
    Reason against 1 of 2
    ?
    • 1.Husserl's phenomenology of time-consciousness shows that perception of motion requires 'retention'—a just-past phase held in living present awareness.
      ?

      Think about whether this reason is strong or weak

    • 2.If motion perception necessarily involves retentional consciousness of immediately prior positions, then motion perception is structurally memory-dependent, not purely direct.
      ?

      Think about whether this reason is strong or weak

    • 3.The qualitative difference between second-hand and hour-hand cases reflects a threshold of retentional decay, not the absence of memory-like processes.
      ?

      Think about whether this reason is strong or weak

    Reason against 2 of 2
    ?
    • 1.Psychophysical evidence from Ternus and Wertheimer demonstrates that apparent motion arises from neural interpolation between discrete positional snapshots.
      ?

      Think about whether this reason is strong or weak

    • 2.If the visual system constructs motion percepts from discrete positional data, then 'direct perception of motion' describes phenomenology but mischaracterizes the underlying representational process.
      ?

      Think about whether this reason is strong or weak

    • 3.Gibson's ecological direct realism, even on its strongest reading, cannot override the inferential computational architecture demonstrated in motion aftereffects and phi phenomena.
      ?

      Think about whether this reason is strong or weak

    But is it possible to perceive something as extended and as present? If we hear a short phrase of music, we seem to hear the phrase as present, and yet — because it is a phrase rather than a single chord — we also hear the notes as successive, and therefore as extending over an interval. If this does not seem entirely convincing, consider the perception of motion. As Broad (1923) puts it, ‘to see a second-hand moving is quite a different thing from "seeing" that a hour-hand has moved.’ It is not
