Our Current State of Progress

Humanity has come a long way in terms of progress and innovation. Catastrophes that once killed millions are now mostly under control. Famine and disease, for instance, have become less of a threat than obesity. War, once a pervasive occurrence, now kills far fewer people. As a species, humankind can now shift its goals. With the help of medicine and technology, we are living longer, happier, & stronger lives, thereby shaping a new definition of human ambition.

The Human Superiority Complex

Humans have dominated the world by domesticating animals and claiming superiority over them. However, this has led to animal suffering while meeting our desire for cheap meat. Despite imagining that we have a “human soul,” there is no evidence of its existence, or that it differentiates us from animals. Furthermore, it’s unclear if human consciousness is any different from animal consciousness. Our ability to cooperate on a large scale may be our true advantage. Nevertheless, it’s essential to reflect on our actions and question whether our treatment of animals is a result of an unwarranted sense of superiority.

The Evolution of Religion

The power of shared narratives has brought us together since the Crusades. As we transitioned from traditional religious beliefs to secular ones, we replaced supernatural beings with moral laws. In a world where science cannot provide moral answers, we still need religion to provide guidance.

The Cost of Rejecting Meaning

The modern era has allowed us to reject divine existence and define our own meaning. We have gained power and can effortlessly improve our lives. However, the cost of this power is the loss of meaning. In the past, we accepted disasters as God’s will, limiting our ability to act. Now we have gained the power to act without limits, but modern society is based on endless growth. If growth stops, so does economic progress. The source of our power is the continued growth and subsequent technological improvements. We can conquer death and preventively treat diseases. Yet, there is a fundamental question to be answered- Have we really gained meaning, or have we lost it in this grab for power? The book concludes that the cost of rejecting meaning may be too high as we continue to strive for progress relentlessly.

Humanism: The Modern Religion

The significance of the world lies in human experience, which is the basis of humanism, the dominant religion in modern society. Humanism values individual experience as the basis for authority, and liberalism is its prominent variant. There are different versions of humanism, and no single one provides all-encompassing solutions. Nationalists would fight for their country, whereas socialists would take from the rich to feed the hungry, and liberals value all human experience equally. However, despite different interpretations, liberalism is the prevailing ideology these days, with no real alternatives. Occupy Wall Street is another expression of liberalism disguised as revolutionary resistance. Nonetheless, as technology advances, liberalism’s relevance and survival remain uncertain.
