TEN: THE EVENTS THAT MATTER II: META-INVENTIONS
In 1884, a book called Flatland describes a two-dimensional world where the narrator, a Square, encounters a three-dimensional Sphere. This encounter illustrates the concept of reconceptualization, where understanding changes dramatically, a phenomenon seen throughout history in the arts and sciences.
Meta-inventions are new cognitive tools that transform how people think and create. Unlike physical inventions, which can be stolen or lost, meta-inventions exist in the mind and can be retained with just memory. They enable broad applications and significant changes in practice and achievement. Common inventions, like the wheel or the printing press, are not considered meta-inventions because they are physical. Language is also excluded, as it is a natural aspect of human development rather than a specific invention.
Written language serves as a prime example of a meta-invention, as it was developed independently in a few cultures. Additionally, there are 14 significant meta-inventions identified since after 800 AD, including artistic realism, logic, and the scientific method. These meta-inventions have each opened new possibilities for understanding and creativity in various fields.
Meta-Inventions in the Arts
Meta-inventions in the arts refer to significant creative breakthroughs that shape artistic expression. The first type of meta-inventions encompasses the fundamental forms of the arts, such as visual art, music, and storytelling, which are universal across cultures and time periods. However, identifying specific landmark innovations, or meta-inventions, that fundamentally changed artistic practices provides a clearer focus.
One major meta-invention is artistic realism, which emerged around 500 BC in ancient Greece. For many centuries prior, art adhered to strict conventions that often prioritized stylization over realistic representation. In Egypt, for example, artists followed rigid rules that depicted figures in non-realistic ways, with body parts represented from different angles simultaneously. This changed during the reign of the pharaoh Akhenaton, who encouraged more naturalistic art. However, it was not until ancient Greek artists returned to this pursuit that true realism began to take shape. They introduced techniques like foreshortening, which allowed for more accurate depictions of depth and proportion. This shift in focus toward observing the real world marked an important evolution in how artists engaged with their subjects, influencing both painting and sculpture.
Another key advance was the invention of linear perspective in Italy around 1413. While some understanding of perspective existed in earlier periods, Filippo Brunelleschi developed a systematic method that allowed artists to create the illusion of depth on a flat surface. His demonstration with a mirror and painting impressed contemporaries, showcasing the newfound ability to replicate the three-dimensional look of buildings and landscapes. This innovation not only transformed artistic practices but also elevated the status of painters, aligning them more closely with philosophers and scientists, as they began to engage deeply with the principles of perspective.
The invention of abstraction emerged in the latter half of the 19th century, revolutionizing the approach artists took toward painting. With the advancements in capturing realistic images through photography, artists felt encouraged to explore new modes of expression beyond literalism. Artists like Édouard Manet challenged the notion of painting as a window to the world, emphasizing the significance of the flat canvas itself. This departure from realism paved the way for various movements such as Impressionism, Cubism, and Surrealism, which brought new ideas about self-expression and the role of the artist.
In music, the invention of polyphony from the 11th to the 13th centuries represented another remarkable advancement. Prior to polyphony, musical traditions largely consisted of single, linear melodies. With polyphony, musicians began stacking different melodic lines, creating a richer and more complex musical experience. Though its exact origins are difficult to pinpoint, early examples appeared in religious settings, where simpler forms of singing evolved into intricate multi-voiced compositions. This foundational change expanded the possibilities of musical expression, leading to more sophisticated harmonies and compositions in the future.
When considering literature, the identification of meta-inventions is more complex, as literature has ancient roots and has developed in various forms over millennia. The invention of drama around 534 BC is a significant turning point. Thespis introduced the concept of an individual character distinct from the chorus, creating a dialogue that set the stage for modern acting. This change opened up new avenues for storytelling and theatrical performance, allowing audiences to engage with narratives in dynamic ways.
The novel represents another vital meta-invention, emerging in Europe around the 1500s. While long fictional narratives existed previously, the modern novel is characterized by its focus on a simulated reality. It explores social dynamics and human behavior in a way that reflects real-life experiences more closely than prior literary forms. This new genre allowed for deeper character exploration and commentary on the human condition, setting it apart from earlier forms of poetry and drama.
Overall, these meta-inventions—notable shifts toward realism, perspective, abstraction, polyphony, drama, and the novel—represent significant milestones in artistic evolution, each building upon previous ideas while creating opportunities for new ways of seeing, hearing, and understanding art. These innovations not only transformed their respective mediums but also reshaped the relationship between the artist and the audience, enhancing the depth and diversity of human expression across cultures and eras.
Why Not Film?
Film is not included in literature inventories because film directors are often not recognized as important creators, while screenwriters are noted only when mentioned. Biographical sources usually do not highlight film directors, and many histories of drama do not include films. Though creating a separate inventory for film might make sense in the future, it seems too early since talking pictures only started appearing 23 years before 1950. The novel became important later, with early works like "La Vida de Lazarillo de Tormes" showing everyday life realistically. Unlike Western novels, countries like China, Japan, and India developed their own storytelling styles only after interacting with the West. The rise of the novel allowed writers to explore human nature and social issues, connecting literature with social sciences.
Meta-Inventions in Philosophy
Philosophy as a systematic study began to emerge after the first civilizations, like Sumer and Egypt, although their philosophical ideas were not recorded. From around 520 to 320 BCE, a significant period of philosophical development occurred across Eurasia. This era saw the founding of major traditions such as Hinduism and Buddhism in India, Confucianism in China, and early Greek philosophy. Key figures included Buddha, Confucius, Thales, Pythagoras, and later the development of Daoism and Confucianism by thinkers like Laozi and Mencius, respectively.
What Is Philosophy?
Philosophy is the study that asks deep questions about existence, such as what the universe is about, what it means to be human, or even the nature of everyday objects like a table. It shares some common ground with religion by exploring important questions about life and ethics, but it differs because it relies on reasoning and thinking rather than faith. This definition allows figures like Thomas Aquinas and Buddha to be seen as philosophers, while the teachings of Jesus and Muhammad are mostly tied to their religious messages.
The roots of Western philosophy began in ancient Greece, specifically in Athens, during a critical period from around 420 to 320 BCE. In this time and place, great philosophers like Socrates, Plato, and Aristotle appeared, leaving behind ideas that still shape how we think today. Despite the challenges of war and disease during this period, these thinkers addressed essential topics like virtue, happiness, and logic, which influence modern ideas about these concepts.
Meditation started in India around 200 BCE as a mental practice aimed at helping people focus their thoughts. It was developed to manage the chaotic nature of human consciousness, where people often have many distracting thoughts. Meditation is now part of many religions and also used in non-religious practices. Although some people see meditation as linked to Asian traditions, like logic, it is a powerful tool for everyone.
At the same time, logic was being developed in Athens around 400 BCE. Philosophers like Parmenides began exploring how to reason and understand what is real. Aristotle later created a system of logic that provided tools for critical thinking and analysis that we still use today. His work laid the foundation for understanding how to differentiate between true and false statements.
Another significant development in philosophy is ethics, which explores ideas about right and wrong behavior separate from religious influence. This concept emerged across cultures, including in China, India, and Greece, around the same time. Ethical thinking shifted from being based on the will of gods or rulers to focusing on what it means to live a good human life and create happy communities.
This new understanding of ethics helped develop political theory, allowing thinkers to discuss the best ways to organize society. They began to ask how a political system could be good for human beings and what makes a fulfilling life. These ideas connected ethics with political thought, influencing concepts like democracy that continue to be important today.
Meta-Inventions in Mathematics
Number systems are important inventions in mathematics, with early examples from Egypt, Sumer, India, China, and the Maya. The Egyptians created the first fully developed number system around 3500 BC. Another key development was positional notation, invented in Sumer around 2400 BC. Other major inventions in mathematics include non-Euclidean geometries, calculus, and Boolean algebra, which each introduced new ways of thinking. The invention of mathematical proof in Greece around 585 BC was a big change from earlier informal methods used by different cultures.
Meta-Inventions in Government and Commerce
In government and commerce, several important ideas have shaped how they work. In commerce, two major inventions date back to around 8000 BC: agriculture and the domestication of animals. These developments led to the idea of division of labor, where different people have specific jobs. Adam Smith later introduced the idea that voluntary exchanges benefit both parties, which means that when people trade, it can help everyone involved. The invention of money and credit started in ancient Sumer, followed by the creation of paper money in 9th century China. Keeping track of money through accounting and the concept of managing risk, influenced by probability theory, were also significant inventions. Mass production, which began in the late 18th century, changed how goods were made.
In government, what counts as an important idea can vary depending on what people believe about government’s role. A key idea is the invention of law, which are rules that help groups function. There’s also the idea that government acts on a contract between those in power and the people. Another important concept is that the government’s main job is to serve its citizens, and that it gets its power from the people’s consent. The idea of natural rights, linked to John Locke in the 17th century, is also noteworthy.
In mathematics, the idea of proofs based on logic created a strong foundation for the field. Thales was one of the first to create mathematical proofs, especially in geometry. The development of mathematical logic came before Aristotle’s ideas and helped shape modern mathematics. The Arabic numeral system, which includes zero, took a long time to develop and involved different cultures. The study of probability began with gambling problems and was advanced by mathematicians like Blaise Pascal and Christiaan Huygens, who established important concepts that help us understand uncertainty today.
Precursors
Pascal’s Triangle was predicted 350 years earlier by the Chinese mathematician Zhu Shijie, showing early ideas in math that were not fully explored. The Talmud was one of the first texts to analyze possible outcomes related to divorce and premarital loss of virginity. Pascal built on Huygens’s structured approach to probability theory, making Huygens’s work more influential. Understanding uncertainty changed how we gain knowledge, leading to important statistical methods in the sciences and better risk management in economics, both essential for modern economies.
Meta-Inventions in Science
There are two important inventions that greatly changed science: the secular observation of nature and the scientific method. The secular observation of nature began around 600 BC in Greece and China. Before this time, people generally thought of nature and its forces as mysterious and controlled by gods. However, during this period, philosophers started to realize that they could observe and understand nature without mentioning gods. This new way of thinking started with Thales of Miletus, who is known for his early observations about the earth and natural events. By looking at things like how plants grow and how weather changes, early thinkers began a process that would lead to the development of science.
In China, people also began to observe nature quite early. By 1300 BC, records show systematic observations of weather patterns, although these were often used for rituals rather than scientific reasons. By 400 BC, Chinese thinkers had already figured out parts of the water cycle. While both Greece and China made important discoveries through observation, the development of science in Europe slowed down after the fall of the Roman Empire, whereas progress in China continued steadily.
The second major invention is the scientific method, which was developed in Europe between 1589 and 1687. This method changed how people gathered knowledge and proved ideas. The scientific method includes steps like forming hypotheses, running experiments, and using mathematics to understand nature. Although Chinese scholars had advanced investigative methods, they did not develop a system that allowed for the steady growth of scientific knowledge as seen in Europe later.
The scientific method developed gradually through new ideas and practices, starting with people like Roger Bacon and Robert Grosseteste. They emphasized the importance of experiments and observations. Grosseteste said that science should begin with things we can observe in the world and then look for explanations. This was a big change from the earlier ways of thinking, which relied heavily on rules and deductions. He also introduced the idea of having hypotheses, which are educated guesses that can be tested and changed if necessary. This concept is known as the principle of falsification.
William of Ockham contributed to the scientific method by suggesting the principle of parsimony. This principle advises that when faced with different explanations, the simpler one should be chosen unless there is a good reason to consider the complex one. This encourages scientists to seek the most straightforward explanation for what they observe.
The idea of controlled experiments also became very important during the 16th century. Galileo is a key figure who used careful observation in his experiments on how things fall. His detailed approach set a new standard for experiments in science. Overall, the combination of these two important inventions changed how people understand the world and laid the foundation for modern science.
Did Galileo Make Up His Data?
Galileo observed that when a lighter object and a heavier object are dropped, the lighter object starts to fall faster at first but is eventually overtaken by the heavier one. Critics claimed that Galileo’s data was wrong, but experiments showed that the lighter object looked like it was falling faster because it was easier to let go of. The heavier object, which needed a firmer grip, was released a bit later, causing it to eventually catch up. This misunderstanding echoed ancient mistakes, where critics judged results based on assumptions instead of actual experiments.
The control over scientific data advanced with Robert Boyle’s invention of the air pump in 1657. Earlier, Blaise Pascal had his brother-in-law take a barometer to a mountain, showing that air pressure changes with altitude. Boyle's air pump allowed researchers to create different air pressures in a lab without needing to climb mountains.
Scientific methods continued to improve over time. Francesco Redi did an experiment to test if maggots appeared from rotting meat or if they were generated spontaneously. He found that only the exposed meat developed maggots, which provided strong evidence against spontaneous generation. As science progressed, techniques like single-blind and double-blind experiments became standard in fields like medicine and psychology.
Galileo also made important distinctions between primary and secondary qualities. He disagreed with Aristotle’s idea that the material aspect of objects was less important than their form. Instead, Galileo argued that the basic physical properties of objects, like size and shape (primary qualities), affect how we perceive secondary qualities, like taste and smell.
The relationship between mathematics and the natural world became clearer during Galileo's time. While earlier thinkers had recognized the role of mathematics in understanding the universe, Galileo showed that it is a language that can explain natural phenomena. He conducted experiments with inclined planes, discovering a consistent link between how far an object travels and the square of the time it takes.
Throughout the 17th century, scientists debated how much they should depend on mathematics. Some, like Boyle, preferred to describe findings using probabilities rather than strict laws. However, Isaac Newton later proved that mathematical laws could accurately predict outcomes of experiments, which changed the outlook on the importance of mathematics in science.
As science evolved, ways to share findings and give credit improved. Girolamo Cardano established the first-to-publish principle, encouraging scientists to share new discoveries quickly. Additionally, detailed scientific reports became essential so other researchers could understand and trust the results without repeating the experiments. This created a culture of open communication in science, allowing for collaboration and reducing mistakes.
Overall, these advancements in how scientists think, observe, and share knowledge show the significant impact of human intelligence on the development of science. There is still potential for new discoveries and tools waiting to be found.
In 1884, a book called Flatland describes a two-dimensional world where the narrator, a Square, encounters a three-dimensional Sphere. This encounter illustrates the concept of reconceptualization, where understanding changes dramatically, a phenomenon seen throughout history in the arts and sciences.
