  • Several species of flora and fauna were impacted due to human activity.

Early Human Societies

  • Early human societies centered around hunting.
  • Hunting was a source of food and a way to demonstrate social standing.
  • War between tribes was common due to resource needs.
  • Peaceful methods of resolving conflicts were discovered around 5,000 years ago.

Trade and Initial Needs

  • "Trade" began as cross-town and eventually cross-cultural interaction occurred.
  • Exchanging of products and initial needs emerged.
  • Trading led to wealth, which became a goal.
  • People who didn't possess wealth had to hunt, farm, and produce goods for profit.
  • Nuclear communities (self-sufficient communities) accommodated growing populations with dwindling resources.

Products Exchanged

  • Crops
  • Cattle
  • Poultry
  • Clothing materials
  • Metal
  • Accessories
  • Weapons
  • Spicies
  • Literature
  • Entertainment

Specialized Artisans

  • Specialization developed, for compensated artisan skills.
  • Farming and agriculture allowed cultivation of crops.
  • Producing surplus food.
  • Establishing permanent settlements.

Tools

  • Hand-held tools (stone axes, spears, arrows, sickles).
  • Farming tools (plows, irrigation systems, storage containers).
  • Construction tools (bricks, mortar, wheelbarrows, simple cranes).
  • Communication and record-keeping tools (writing systems, clay tablets, papyrus, parchments).
  • Trade and transportation tools (wagons, carts, roads, bridges)

Intricacies of Today

  • Machines were created and causes endeavored
  • People developed methods for warding off evil (e.g., concocted potions).
  • The concept of morality is important.
  • Different races, beliefs, and abundant resources led to wars.
  • Communities allocated resources for the militia.

Advantages of Modern Era

  • Physical strength was valued most in early times, though intellectually gifted innovators were also present.
  • Technological advancements (e.g., medicine, health, education) have improved daily life significantly.

Notable Comparisons Then and Now

Mortality Rate

  • Women and children were vulnerable to death during childbirths due to limited medical knowledge and resources.
  • Premature births and complications resulted in loss of both mother and baby.
  • Modern advancements (prenatal care, improved surgical techniques, antibiotics) reduced mortality rates, and made childbirth safer.

Average Lifespan

  • People were susceptible to diseases (like smallpox, tuberculosis, and cholera).
  • Limited healthcare and sanitation contributed to shorter lifespans.
  • Medicine and sanitation increased average lifespan dramatically.
  • Development of new treatments helped manage chronic diseases.

Literacy Rate

  • Primary literacy meant the ability to read and write, accessed via limited resources like cost and location.
  • Technology increased access to information.
  • "Digital literacy" is a modern concept that encompasses computer skills and information literacy.
  • Concerns exist regarding the potential negative impacts of digital technologies on deep reading skills and critical thinking.

Gross Domestic Product (GDP)

  • GDP calculations (nation's economic output) focused mainly on tangible goods and traditional industries (like manufacturing, agriculture, and resource extraction).
  • Calculation expanded to include intangible products like cloud computing, data centers and mobile technologies.

Essence of Technology

  • Humanity has come a long way from primitive ways.
  • Technology improved life, made it more comfortable for many, due to scientific breakthroughs.
  • Modern humans are reliant on technology for the good life, recognizing natural ways to improve lives.

Old Technology versus New Technology

Technology: a tool or Way of Life?

  • Technology is often goal-oriented.
  • Technology is seen as an instrumental aspect in goal achievement, a purposeful craft that humans utilize to reach greater goods.
  • In a postmodern era, the deterministic view of technology is questioned by people.

Heidegger's Perspective

  • Martin Heidegger argued that technology's essence differs from its purpose and its being.
  • Technology is a means to achieve human goals and constitutes human activity.

Second Perspective

  • Each technology era reveals a particular characteristic regarding human being.
  • Introducing new technology results in a myriad of new questions.
  • Humans use technology to confront the unknown and understand their reactions.

Essence of (continued)

  • Technological revelation is only one way to understand the world.
  • The world is often viewed as a field of resources with monetary value given to everything.
  • Human beings categorize nature into "renewable" and "non-renewable" resources based on their perceived value.
  • Humans are reduced to the amount of productivity they generate in their lives.
  • Practical skills are emphasized and valued, and individuals are compensated based on their labor.
  • People continue to seek answers through science or religion.

Negative Effects

  • Excessive dependence on technology can make a person lose track of important values.
  • This can diminish the economic and surrounding values of things.
  • Dedicating oneself to technology and science to the exclusion of all other considerations can be detrimental.

Essence of Technology (continued)

  • Technology provided explanations, and benefited people.
  • The process of tried-and-tested work does well for people.
  • Should embrace the unknown as one should retrace their steps in achieving the "good life."

Backtracking the Human Condition

  • Technology has fulfilled initial promises; it has increased comfort for many,
  • Scientific breakthroughs have improved lifestyles, especially for the affluent.
  • (Examples: factory machines, robotic arms, spaceships, space exploration, modern gadgets.)

Backtracking the Human Condition (continued)

  • Many still face struggles with survival (diseases, wars, resource competition).

  • Global inequalities persist.

  • Wars, disputes over territory, race, and beliefs continue.

  • People still seek meaning through religion or science.

  • Religion explains the unknown; science offers discovery.

  • Both remain methods of seeking meaning and sense of existence.

Backtracking the Human Condition (continued)

  • Technology only enhances sophistication but not human conditions.
  • Despite advancement, human conditions remain the same (struggles for survival, conflict, and meaning).

Backtracking the Human Condition (continued)

  • Technology cannot define the good life.
  • Aristotle: human flourishing comes from societal virtues (wisdom, courage, justice) resulting in fulfillment.

Backtracking the Human Condition (continued)

  • Technology is rapid but lacks moral consideration.
  • Aristotle's good life depends on virtues, not efficiency.
  • A good life balances virtues, innovation, and ethics.

Backtracking the Human Condition (continued)

  • Technology provides comfort and innovation but doesn't define the good life.
  • Embracing virtues, holistic views of flourishing are fundamental for a good life.
  • Questioning what "living well" truly means.
