We play games with each other to learn about each other; we play games of solitaire to learn about cards.
Toys are all about learning, unless one prevents them from being so: for one must at least learn to look after one's toys.
Educational toys are about teaching something which is magic to us: for, in order to impart knowledge, the only device we need is willingness on the part of the protege. The mentor is always willing.
Toys can get us into trouble. The Universe is made up of infinitesimally sized lego bricks, and light. But what is light?
It is a frustrating question because here it is in front of us, thus it must be understood. Yet those we must ask can surely see right through us?
Without any device.
