Final answer:
Martin is governed by his id, and Antonio by his superego, according to Freud's theory on the id, ego, and superego as parts of the human psyche.
Step-by-step explanation:
According to Freud, Martin is governed by his id, which is the part of the personality that seeks immediate gratification and operates based on the 'pleasure principle.' His friend Antonio is guided by his superego, which acts as a moral compass and strives for perfection, following the 'reality principle.' The id seeks immediate gratification of basic drives and desires, whereas the superego develops through social interactions, learning rules for right and wrong, and acts as our conscience. The ego is the rational part that balances the id and superego.
