Cognitive Revolution: Lecture Notes

Overview

  • 30,000 years ago: Human handprints in southern France.
  • 13.5 billion years ago: Big Bang; formation of matter, energy, time, and space (Physics).
  • 300,000 years after Big Bang: Atoms form molecules (Chemistry).
  • 3.8 billion years ago: Formation of organisms on Earth (Biology).
  • 70,000 years ago: Homo Sapiens form cultures (History).
  • Three revolutions: Cognitive (70,000 years ago), Agricultural (12,000 years ago), Scientific (500 years ago).

Impact of Homo Sapiens

  • Prehistorage: Homo Sapiens were initially insignificant.
  • Evolution and development of culture led to advancements like lunar exploration and genetic understanding.
  • Classification of organisms into species and genus; humans belong to Homo sapiens.
  • Evolution of different human species (e.g., Neanderthals, Homo erectus).
  • Homo sapiens survived and thrived over other species through cultural and cognitive developments.

Cognitive Revolution

Species and Evolution

  • Human evolution began around 2.5 million years ago in East Africa from Australopithecus.
  • Evolution led to distinct human species: Homo erectus, Homo soloensis, Neanderthals, Homo sapiens.
  • Extinction of sibling species and dominance of Homo sapiens.

Cognitive Abilities

  • Larger brains in humans but also higher energy consumption and physical limitations (e.g., childbirth hazards).
  • Cognitive skills: planning, language, social abilities.
  • Early human social structures and group sizes.

Language and Social Structures

  • Unique human ability to invent and pass on complicated cultural myths and stories enabled large-scale cooperation.
  • Cognitive Revolution: Shift from small groups to large complex societies through shared myths and flexible cooperation.

Development of Culture and Society

Early Human Culture and Artifacts

  • Limited by perishable materials; most tools made from wood.
  • Seasonal and migratory band lifestyle; eventual development of agricultural settlements.
  • Social hierarchy and division of labor based on evolved traits and cultural norms.

Impact of Language and Mythology

  • Language simplified interactions and fostered large social groups and more advanced cooperation strategies.
  • Myths and religion helped unify and control larger human populations with common beliefs and norms.
  • Evolution of complex societies through shared beliefs and values.

Agriculture and Human Societies

Dawn of Agriculture

  • Shift from hunter-gatherer societies to settled agricultural communities around 10,000 years ago in the Middle East.
  • Domestication of plants and animals; shift in social structures and division of labor.
  • Agriculture enabled permanent settlements, property accumulation, and social hierarchies.

Social and Economic Changes

  • Development of complex societies, cities, and later, empires due to stable food production and surplus.
  • Conflicts over resources led to fortified settlements and militaristic societies.
  • Rise of social stratification and specialized roles beyond basic survival tasks.

Unification of Humankind

Empires and Trade

  • Empires played a significant role in cultural merging and the emergence of larger societies and cultural norms.
  • Historic examples: Roman Empire, Persian Empire, Chinese Empire, and their impacts on global culture.
  • Exchange of goods, ideas, and cultural practices through trade routes and conquests.

Modern Global Culture

  • Cultural globalization accelerated by technological advancements and economic trade (e.g., mixing of culinary practices, language proliferation, etc.).
  • Economic, political, and scientific collaboration forming a global society with interconnected systems.

Scientific Revolution

Characteristics of Modern Science

  • Admitting ignorance and basing theories on empirical observations and mathematical formulations.
  • Constantly evolving understanding of the world through testing and disproving existing theories.
  • Integration of science, technology, politics, and economics forming the bedrock for advancements in human society.

Developments and Impact on Society

  • From Galileo to modern-day quantum mechanics, scientific discoveries have transformed daily life and global power structures.
  • Relationship between science and technology underscored by governmental and corporate funding influenced by political and economic interests.

Future of Human Society

  • Increasing scientific breakthroughs in genetics, nanotechnology, and artificial intelligence ever-more shaping the socio-political landscape.
  • Potential ethical dilemmas from scientific advancements, balancing human needs with moral implications of research and technology.

Conclusion

  • Cognitive revolution, agricultural advancements, and modern science have all shaped human society significantly.
  • Understanding history is crucial for shaping a scientifically informed and ethically balanced future.
