Answer:
egocentric.
Step-by-step explanation:
The Ring of Gyges is a mythical artifact used by Plato in his book entitled 'Republic.' In the story, Glaucon recounts a myth of Gyges. In the myth, there was a shepherd named Gyges who found a ring which makes man invisible on a corpse of a man.
Using the invisibilty power of the ring, Gyges seduced the queen Lydia, made her murder her King, after which Gyges became the King. Through this myth, Glaucon wanted to convey that people are naturally egocentric.
Egocentric can be defined as a disability of overlooking others needs and desires. An egocentric person is self-centered, thinking all about just himself.
Thus the correct answer is egocentric.
