a. Information leaves the table= a motion in the object sends information to our senses, in this case the eye.
b. Information passes through the eye= motion in our senses, i.e. the eye, receives the information
c. Information arrives in the mind, where it is "viewed" by the mind's eye=I have an image of the table
2. NOTE: The above process Locke described in the 18th century, we can describe using different terminology now: Instead of saying there is a motion in the table and another one in the eye, most likely what we say is the table "gives off" light waves and the nerves in our eyes "process" the information and send it to the brain.
3. Hence, Locke argues that all the knowledge I have of the table is my mental image, i.e. the idea of the table. And since I cannot compare the idea with actual object, I do NOT know if the mental image is an accurate one. Practically, we do not look out at the external world; rather, we look at our inner images of the world and hope that these images/ideas are an accurate representation of the external world.
