THE DEFINITION OF PERCEPTION

God's omniscience, but in such abnormal perceptions as illusion, liallucination, dream, delirium and the like In these cases we have perceptions of objects that are not in actual contact with our senses. No doubt they are all cases of wrong knowledge, but that they are actual perceptions we cannot dispute. When we have such experiences or when afterwards we recollect them, we feel that we did perceive certain things which we should not have so perceived. These then are significant experiences which show that perceptual knowledge is not essentially a matter of senseobject contact. Similarly, any ordinary valıd perception is found by analysis to contain elements wluch are not sensations in any sense When we perceive an orange from a distance, we have a sensation of its colour but not of its smell, taste and touch Still we perceive all these qualities as constituents of the total percept! Hence it may legitimately be said that sense-stimulation is not the essence of perception. Wherein that essence lies we may also find in the light of the above instances They serve to show that we feel sure to perceive anything that is directly piesented to us. It does not matter much whether the direct presentation, which we call perception, is right or wrong, is by way of sense or not.

None of these is completely trustworthy, but they are all we have."
