In this blog post, we explore the possibility that advancements in human technology and intelligence could extend human lifespan indefinitely, and analyze the impact of biological limitations and social factors on this prospect.   Homo Deus and the Possibility of Immortality Humans survive by exerting a more destructive and far-reaching impact on the Earth’s ecosystem than any other life...

In this blog post, we will examine whether advances in science and technology expand human free will or confine it within the constraints set by genetics.   Is destiny predetermined? First, before beginning this blog post, I would like to introduce the myth of Oedipus. The myth of Oedipus is the story of a hero who succumbed to fate. The general plot is as follows. Laius, king of ancient...

In this blog post, we explore the debate over whether human behavior and personality are determined by genes or shaped by the environment.   For hundreds of years, across both the East and West, humanity has engaged in a constant debate over whether humans are determined by nature—that is, by their genes—or shaped by nurture—the environment of upbringing, including experiences and education...

In this blog post, we’ll explore why humans go beyond their instinctive self-interest to help others, and how communication fosters altruism.   Have you ever seen someone around you who lives their life for others rather than for themselves? You don’t have to look far—most parents fit this description. If we consider humans to be rational beings who instinctively prioritize their own...

In this blog post, we will examine, from an evolutionary perspective, how the cognitive genes and memes unique to humans interact to drive the formation and development of civilization.   Why We Must Interpret the Origins of Civilization from an Evolutionary Perspective Over a long period of time, humanity has explored the origins of its own civilization and proposed various compelling...

In this blog post, we’ll explore the principles behind how the cone cells in the human eye perceive and distinguish various colors.   You’ve probably heard at least once that dogs and cats are colorblind, and that only humans can distinguish colors. In fact, pets see the world differently than we do. They either cannot detect certain colors or can only see within a limited color range...

In this blog post, we’ll start by exploring the question of whether humans can dive into the deep sea like whales, and then examine the human body’s diving reflex mechanism and its scientific feasibility.   When you first learned that whales—which swim for long periods in the deep sea—are not fish but mammals like humans, were you surprised? It is astonishing that these creatures, which we...

In this blog post, we take an in-depth look at whether human cloning could be an innovation that brightens humanity’s future, or a dangerous experiment that threatens human dignity.   Cloning is a term that refers to the production of an individual identical to a natural specimen. This term has been garnering increasing attention alongside advancements in science and technology. In...

In this blog post, we look beyond the instinctive aversion and ethical debates surrounding human cloning to explore in depth the balance between scientific feasibility and social acceptance.   In February 1997, the Roslin Institute in the UK announced news that stunned the world: the birth of Dolly, the cloned sheep. Dolly, the world’s first mammal born through somatic cell cloning, caused a...

In this blog post, we will examine how the principle of frontality used in New Kingdom Egyptian wall paintings expressed the aspiration for eternal life.   ‘New Kingdom Egyptian wall paintings’ are completely different from Greek art. Figures depicted in Egyptian murals and paintings typically have their heads turned to the side, their upper bodies facing forward, and their feet turned to...
