Bernard of Chartres (circa 1070 – 1130)

Bernard of Chartres, a prominent 12th-century French philosopher, lived around 1070 to 1130. He is best known for his influential teaching that emphasized the continuity of knowledge through the ages. Bernard is famously credited with the phrase, “We are like dwarfs on the shoulders of giants,” highlighting the idea that contemporary scholars build upon the

Cultural Transmission

30 Phil, Chapter 1 Touchstone 4: Cultural Transmission. Cultural transmission, perhaps more than any other trait, sets humans apart from other animals. It’s the ability to pass behaviors, traditions, and knowledge to the next generation. Cultural transmission has likely been a feature of our direct-line hominin mind for millions of years. Returning to what we

Evolution

30 Phil, Chapter 1 Touchstone 3: Evolution. In 1859, the naturalist Charles Darwin revolutionized the scientific world with his seminal publication, “On the Origin of Species.” In it he formulated his scientific theory of evolution by natural selection. The process by which new species arise is well-understood. It proposed that changes in species occur gradually over time. With each generation,

Free Will

30 Phil, Chapter 1 Touchstone 2: Free Will. There are two basic types of Free Will. Determinism says everything that happens is set in stone and can’t be changed; in contrast, indeterminism says people and animals make choices. There are four basic types: scientific determinism, scientific indeterminism, fatalism, and providence.

Neanderthal-Sapien LCA

NSLCA: The Neanderthal-Sapien Last Common Ancestor was likely Homo heidelbergensis or Homo antecessor. Analysis: Before the discovery of Homo antecessor in the 1990s, Homo heidelbergensis was considered the primary candidate for the NSLCA due to its chronological and morphological position in the human lineage. The discovery of Homo antecessor, with its more modern-looking facial features, has

Emergence of the Great Apes (Great Apes LCA)

660,000 Generations Ago The Last Common Ancestor (LCA) of the Great Apes, a.k.a. the Hominidae family, marks a pivotal point in our evolutionary history, encompassing the origins of orangutans, gorillas, chimpanzees, and humans. This ancestor species, likely existing between 15 to 19 million years ago, represents the shared lineage from which all modern great apes

First Atmosphere: Hydrogen & Helium

Likely white or grayish atmosphere: The first atmosphere developed first but was not directly involved in the development of life. The first atmosphere formed shortly after Earth’s formation around 4.5 billion years ago. This initial atmosphere was primarily composed of hydrogen and helium, the lightest and most abundant elements in the universe, which were captured from

Big Bang Expansion

30 Phil, Chapter 1 Touchstone 1 of 80: Big Bang. Immediately following the state of the singularity, the universe entered a phase of rapid expansion and cooling, known as the Big Bang Expansion. This critical period signifies not an explosion in space but the very expansion of space itself, from an incomprehensibly dense point known

The First True Eukaryotes

All life today are either Prokaryote or Eukaryote. Around 2 billion years ago, Eukaryotes evolved from Prokaryotes. The evolutionary leap to eukaryotes introduced cells with a nucleus and membrane-bound organelles, a complex architecture derived from prokaryotic predecessors through endosymbiosis. This process, crucial for eukaryotic evolution, involved the incorporation of prokaryotic cells into the cytoplasm of

Earth is Born

The Earth and the other planets formed 4.5 billion years ago from the same cosmic cloud—the primordial material which gave birth to the Sun. The dust and comets—the rocks—were composed largely of hydrogen, ice, carbon, and nitrogen.

Birth of the Sun

4.6 billion years ago, a cloud of gas and dust collapsed under the force of its own gravity to form our solar system.With the Sun at its center, glowing, the planets had not yet formed. The Sun, a G-type Population 1 star, shines brightly with a surface temperature of about 9,400 degrees, 5,500 Kelvin, and

First Atoms

The image of the early universe that we see in the CMB reveals a time shrouded in darkness. During this era, the 17 known particles first started to combine to form the universe’s first atoms. Electrons, protons, and neutrons came together to create neutral hydrogen atoms, a process that allowed photons—or light—to traverse the cosmos
