"We are conscious of ourselves because we are conscious of others; and in an analogous manner, we are conscious of others because in our relationship to ourselves we are the same as others in their relationship to us. I am aware of myself only to the extent that I am as another for myself."

- Lev Vygotsky

"In play a child always behaves beyond his average age, above his daily behavior. In play it is as though he were a head taller than himself."

- Lev Vygotsky
