You are in the supermarket pushing a cart. You are in front of the shelves with apples that are neatly stored according to taste, kind and variety. It is fruit you need for your health and you buy it, if the price is acceptable. You look at the quality label and then put a pack of six in your cart and go to the till.
It is not because you look that you see. Your biological eye sees shapes and different colours.
But do we actually 'see' what we are 'looking’ at?
