Document Summary

Compares our ordinary sense of reality to that of prisoners in a cave. Platos picture basically stated that your understanding of reality and even your sense of imagination is restricted to those things that you can perceive through your senses. You can never step into the same river twice -> basically saying everything is constantly changing: this is also true for our perceptual experiences, this is true because, every experience changes the following experience. Perception quickly comes to ignore anything that stays the same for a very long time. Adaptation: a reduction in response caused by prior or continuing stimulation. All of our sense adapt to constant stimulation. Had complete trust in sense: the world is made up of atoms that collide with one another. The absolute threshold level is when you can hear the sound 50% of the time. Method of limits: this is a more efficient approach rather than the method of constant stimuli.
