Specs
Pros
Pro Well-researched, vivid descriptions of people
Philip K. Dick manages to excellently explain what a character feels or is thinking through small tells such as body language or involuntary body responses. He often uses these things to illustrate the warmth of humans and coolness of androids.
Pro In-depth exploration of empathy
Empathy and what it means to be empathetic is the main theme of the book and is something that each character has to deal with in one way or another.
The protagonist's belief that the ability to empathise makes one alive and that androids are incapable of true human emotion allows him to due his work as a bounty hunter that retires androids. Once he learns that some androids may be capable of empathy and some people are capable of eliminating empathy, he has to re-evaluate his stance.
