All the mentions of children in PKD's "Androids" are either about someone's childhood:
...he remembered how in his childhood it had been discovered that species upon species had become extinct and how the 'papes had reported it each day...
...He loved Horace more than any cat he ever had, and he's had a cat since he was a child.
or about someone who looks like a child:
A figure like a child's, flat and tame.
or in theatre plays:
Papageno: 'My child, what should we now say?'
Pamina: 'The truth. That's what we will say.'
Were there no kids on the Earth in PKD's novel? Were they just so insignificant to the author that PKD decided not to mention them?
