An analogy of the relation ship between the offspring and its mother, as it is born and separated from her womb, just so it can be reunited with her in the outside world, when it will enjoy from her breast its first taste of pleasure, food, nourishment that now again connects it with its mom, and thus an object is born, and since it is born this thing is alive.
Interesting view, however Harry Harlow would disagree, as his experiments demonstrated the link between mother and offspring was beyond nourishment and attachment was related more to physical contact http://en.wikipedia.org/wiki/Harry_Harlow#Partial_and_total_isolation_of_infant_monkeys
