To attain knowledge, man and woman had to be willing to give up their innocence," says Boris Lehman. Life Lesson is a poetic and philosophic reflection on the theme of paradise lost. Some fifty persons illustrate the planet's convulsions and the world's vacillations. Trying to communicate, to commune with the invisible, they cry out, sing out, give out messages, each in their own way, in their own state of solitude.

He says that if we look at the invisible we may hear the words. He invites us to look beyond the appearances of social life and to vibrate in tune with life's polyphony that is all around us."
