Renaissance and Enlightenment Views on Reality

The Renaissance (14th to 17th century) and the Enlightenment (17th to 18th century) were pivotal periods in European history that profoundly transformed perceptions of reality. These eras witnessed a shift from a predominantly religious and superstitious worldview to one grounded in humanism, science, and reason. The transformations during these periods laid the foundation for the modern understanding of the world and humanity's place within it.

This article analyzes how the shifts during the Renaissance and Enlightenment periods changed perceptions of reality. It explores the key developments in art, science, philosophy, and society that challenged traditional beliefs and introduced new ways of thinking about the world.

The Renaissance: Rebirth of Classical Knowledge

  • Emphasized observation and experience over traditional doctrines.

Impact on Perceptions of Reality

• Questioning Traditional Authority: The revival of classical texts led to skepticism towards medieval scholasticism and Church doctrines.
• Empirical Observation: Emphasis on observation and experimentation over accepted beliefs.
• Human-Centered Worldview: Shift from a theocentric (God-centered) to an anthropocentric (human-centered) perspective.

  • Father of modern chemistry.
  • Identified and named oxygen and hydrogen.
  • Law of Conservation of Mass.
• Carl Linnaeus (1707–1778):

Shifts in Perceptions of Reality

From Theocentric to Anthropocentric Worldview

• Rise of Secular Institutions:
  • Universities and scientific societies promoted independent inquiry.
  • Royal Society of London (founded in 1660) fostered scientific communication.

Emphasis on Observation and Experimentation

• Scientific Method:
  • Developed by thinkers like Francis Bacon (1561–1626).
  • Systematic observation, measurement, experimentation, and formulation of hypotheses.
