     There seems never to have been a civilization without toys, but when and how they developed

is unknown.  They probably came about just to give children something to do.

     In the ancient world, as is today, most boys played with some kinds of toys and most girls with

others. In societies where social roles are rigidly determined, boys pattern their play after the activities

of their fathers and girls are being prepared, even in play, to step into the roles and responsibilities

of the adult world.

    What is remarkable about the history of toys is not so much how they changed over the centuries

but how much they have remained the same.  The changes have been mostly in terms of craftsmanship,

mechanics, and technology. It is the universality (普遍性) of toys with regard to their development in

all parts of the world and their persistence to the present that is amazing. In Egypt, America, China,

Japan and among the Arctic (北极的) people, generally the same kinds of toys appeared. Variations

depended on local customs and ways of life because toys imitate their surroundings. Nearly every

civilization had dolls, little weapons, toy soldiers, tiny animals and vehicles.

     Because toys can be generally regarded as a kind of art form, they have not been subject to

technological leaps that characterize inventions for adult use.  The progress from the wheel to the

cart to the automobile is a direct line of ways up. The progress from a rattle (拨浪鼓) used by a

baby in 3,000 BC to one used by an infant today, however, is not characterized by inventiveness

(独创性). Each rattle is the product of the artistic tastes of the times and subject to the limitations

of available materials.
