Comment this assertion:"cut off from his religious, metaphysical roots, man is lost"

The play has often been viewed as fundamentally existentialist in its take on life. The fact that none of the characters retain a clear mental history means that they are constantly struggling to prove their existence. Thus the boy who consistently fails to remember either of the two protagonists casts doubt on their very existence. This is why Vladimir demands to know that the boy will in fact remember them the next day. The men are essentially waiting for Godot or "God" to validate their existence and reason for being alive.
