When we look across a field, how do we know that one distant object is bigger than another or that one object is behind another, not in front of it? In other words, how do we see things in three dimensions, in proper relation to each other, instead of seeing every thing “ flat ”? The answer is that when we see things we see things in the light of experience. Our minds and memories help us to interpret what we see. For instance, experience gives us an idea about the size of things. A man on a boat some distance from the shore looks much smaller than a man on the beach. But you don’t think that one is very large man and the other a very small man. What you say to yourself is that one man is nearby and the other is far away.
