Racionalismo x Empirismo (resumo) | FILOSOFIA

Understanding Rationalism and Empiricism

Overview of Philosophical Currents

• Rationalism and empiricism are philosophical movements that emerged in the early modern period, focusing on how we acquire knowledge and understand reality.

• Rationalists believe that human knowledge originates from reason, asserting that truth can be reached through logical thought processes.

Key Concepts of Rationalism

• Mathematics is highly valued by rationalists as a precise tool for understanding reality; for instance, the equation 2 + 2 = 4 does not rely on sensory perception.

• They argue for the existence of innate ideas—concepts present at birth that form the foundation of all possible knowledge (e.g., mathematical concepts, geometric shapes, and notions of God).

• Prominent figures in rationalism include René Descartes, Baruch Spinoza, and Gottfried Leibniz.

Key Concepts of Empiricism

• In contrast, empiricism posits that knowledge comes from sensory experience; we learn about the world through our senses (touch, sight, smell, taste, hearing).

• Empiricists reject innate ideas; John Locke famously described the mind at birth as a "tabula rasa" or blank slate.

• Initial ideas arise from sensations—simple ideas shaped by external objects' qualities (e.g., colors like yellow or white).

Development of Ideas Through Reflection

• More complex ideas emerge from reflection upon simple sensations. For example:

• A simple idea: feeling a blue fabric's texture.

• A complex idea: imagining a red fabric's texture based on previous experiences with other fabrics.

Illustrating Differences Between Rationalism and Empiricism

• An illustrative example involves a tree falling in an empty forest:

• Empiricists argue no sound occurs without someone to hear it.

• Rationalists contend that sound exists due to physical laws regardless of observation.
