colours. There are also millions of “rods” but these are used for seeing when it is nearly dark. They show us shape but not colour. Wait until it is dark tonight, then go outside. Look round you and try to see what colors you can recognize.
Birds and animals which hunt at night have eyes which contain few or no cones at all, so they cannot see colours. As far as we know, bats and adult owls cannot see colours at all only light and dark shapes. Similarly cats and dogs cannot see colours as well as we can.
Insects can see ultra

grey and dull to us, but to insects they may appear beautiful, showing colours which we cannot see. Scientists know that there are other colours around us which insects can see but which we cannot see. Some insects have favorite colours. Mosquitoes like blue, but do not like yellow.

Text 3
A child who has once been pleased with a tale likes, as rule, to have it retold in identically the same words, but this should not lead parents to treat printed fairy stories as sacred texts. It is always much better to tell a story than read it out of a book, and, if a parent can produce what, in the actual circumstances of the time and the individual child, is an improvement on the printed text, so much the better.
A charge made against fairy tales is that they harm the child by frightening him or arousing his sadistic impulses. To prove the latter, one would have to show in a controlled experiment that children who have read fairy stories were more often guilty of cruelty than those who had not. Aggressive, destructive, sadistic impulses every child has and, on the whole, their symbolic verbal discharge seems to be rather a safety valve than an incitement to overt action. As to fears, there are, I think, well
authenticated cases of children being
dangerously terrified by some fairy stories. Often, however, this arises from the child having heard the story once. Familiarity with the story by repetition turns the pain of fear into the pleasure of a fear faced
.

and mastered.
There are also people who object to fairy stories on the grounds that they are not objectively true, that giants, witches, two
headed
dragons, magic carpets, etc., do not exist; and that, instead of indulging his fantasies in fairy tales, the child should be taught how to adapt to reality by studying history and mechanics. I find such people, I must confess, so unsympathetic and peculiar that I do not know how to argue with them. If their case were sound, the world should be full of madmen attempting to fly from New York to Philadelphia on a broomstick or covering a telephone with kisses in the belief that it was their enchanted girl friend.
No fairy story ever claimed to be a description of the external world and no sane child had ever believed that it was.

against fairy tales argue that .
