The work suggests that Prometheus is far more important than a fire-bringer. He has also given human beings blind hope and deprived them of the power to see their deaths. Prometheus, since he is immortal, can take some comfort in his foreknowledge. Human beings, on the other hand, would be unable to function if they could see their deaths. Once one knows the limits of one's life, that life seems to lose meaning. Hope, on the other hand, allows human beings to strive toward a goal without knowing whether that goal can be reached. Hope, then, is a psychological mindset necessary for progress. Fire, is the root of art and technology as Hephaestus and Prometheus have both mentioned. Thus, it is a tool needed for progress. By providing humanity with both hope and fire, Prometheus has equipped human beings to attain progress. This contrasts sharply with an earlier Greek worldview. Hesiod believed that the world had moved progressively from the paradise of the Golden Age through the Silver Age, the Bronze Age, and finally the most miserable of all, the Iron Age. Without explicitly rejecting the old view that humanity has slowly been going downhill, Aeschylus advocates a more optimistic belief that progress, fueled by hope and attained through technology, will steadily improve human life.
Prometheus's account of the war between Zeus and the Titans demonstrates an interesting feature of the way the gods carry out their business—that conflicts between gods are painted as politics as usual. Prometheus did not exactly help Zeus out of friendship, and it is not entirely fair to accuse Zeus of violating friendship. Rather, Zeus violated a political alliance. Prometheus first sided with the Titans, but since they would not listen to him, he took what he considered the best option and sided with Zeus. Earth, Prometheus's mother, predicted that guile, or intelligence, would win over force. This was what Prometheus brought to Zeus after the Titans had rejected it, ensuring the new tyrant's victory. Like Zeus, then, Prometheus is guilty of betraying former allies. The political nature of the gods' rule also helps to explain what many scholars see as a serious difficulty with the play. Zeus is clearly angry with Prometheus, will not cooperate, and dominates entirely through force. The trilogy almost certainly ends, as we have seen and as Prometheus has prophesied, with a reconciliation and "friendship" between the two gods. This raises the question of whether Zeus somehow matures and grows wiser in the intervening time. Some formidable Greek scholars insist that, according to the logic of Greek myth, Zeus must remain eternally unchanging in character. The political model explains the possibility of future reconciliation between Prometheus and this unchanging Zeus. Zeus joined with Prometheus when he needed him, and broke the alliance when it threatened him. In the future, faced with a greater threat, Zeus will simply have to reestablish his alliance to secure his throne. No maturation is needed here; only political prudence is called upon.
The role of intelligence in establishing power is also important. Certainly the case is not a simple one of Zeus as force and Prometheus as intelligence. Yet Prometheus's intelligence does seem to be what helped establish Zeus's power. The suggestion is that neither force nor intelligence can survive on its own. Nothing good can come of facing the two off against each other. Intelligence is an essential component in tilting the balance of power from one side to another. This is interesting also because intelligence is precisely what Prometheus gives to humanity, as we will see in the next section. The importance of intelligence in deciding who holds power suggests that Prometheus has aided humanity in raising its resistance to the forces of nature.
