Quote by Richard Dawkins
A retaliator behaves like a hawk when he is attacked by a hawk, and like a dove when he meets a dove. When he meets another retaliator he plays like a dove. A retaliator is a conditional strategist. His behaviour depends on the behaviour of his opponent.

Summary
This quote explains the concept of retaliatory behavior based on the interaction between individuals. It suggests that a retaliator adapts their response depending on the other person's actions. If attacked, they respond aggressively like a hawk, but if faced with peace, they respond peacefully like a dove. When encountering another retaliator, they adjust their behavior, resembling a dove to avoid escalating conflicts. Essentially, a retaliator is portrayed as a tactical thinker, whose actions are dependent on the behavior of their opponent.
