By giving material expression to force-forms in space, the Greeks gave divine spiritual beings the opportunity of using these material forms. It is no figure of speech but a fact when we say that gods came down at that time into the Greek temples in order to be among human beings on the physical plane.

Putting together philosophy and children would have been difficult for most of history. But very fortunately for me, when I started graduate school there was a real scientific revolution taking place in developmental psychology.
