Veridical cognition occurs in memory, anticipation and perception. A perception is ostensibly veridical when its events or data are accorded an immediate and current presence. Anticipation includes the veridical inferences of common sense and science. For instance, while repeating a successful experiment a scientist may correctly infer and visualize the result before it actually occurs. Common sense expectation, although less sophisticated than science, is also inferential. Even the occasional "spontaneous" forethought is presumed inferential in principle. There are also ostensible non-inferential veridical post-cognitions. These are our personal memories, such as today's image of yesterday's sunset.
There are other forms of veridical cognition less prevalent than these. Telepathy and clairvoyance are modes of perception, apparently discerning mental and physical phenomena without the organs of sense. Retrocognition is the apprehension of a past event, the original of which was never experienced by the subject. Such a claim is made by the Misses Moberly and Jourdain in their account of veridically perceiving the Petit Trianon at Versailles at the time of Marie Antoinette2 Retrocognition is not a form of memory without some hypothesis of continuity, such as transmigration of personality. Finally, there is ostensible non-inferential veridical precognition, a peculiar form of anticipation which prospectively refers to an event which has not yet occurred.
