Empiricism, as a philosophical doctrine, asserts that knowledge comes primarily from sensory experience.

Its roots can be traced back to ancient Greek philosophy, particularly to thinkers like Aristotle, who emphasized observation and experience in understanding the world. However, it wasn’t until the 17th and 18th centuries that empiricism became a central philosophical movement, largely in response to the rationalism that dominated European thought.

During the Scientific Revolution, Francis Bacon played a pivotal role in developing empirical methodologies. He criticized the heavy reliance on deductive reasoning and proposed the inductive method, advocating for systematic observation and experimentation. Bacon’s ideas laid the groundwork for the modern scientific method and influenced subsequent philosophers who emphasized empirical evidence.

In the late 17th century, John Locke further advanced empiricist thought with his work An Essay Concerning Human Understanding (1690). Locke argued against innate ideas, proposing instead that the mind is a “tabula rasa” or blank slate at birth. According to Locke, all knowledge derives from experience, either through sensation (external experiences) or reflection (internal mental processes). His ideas significantly impacted epistemology and education, emphasizing the role of environment and experience in shaping individuals.

George Berkeley and David Hume continued the empiricist tradition in the 18th century. Berkeley took Locke’s ideas to an extreme in his subjective idealism, arguing that material objects do not exist independently of perception—”to be is to be perceived.” Hume, on the other hand, applied empiricism to question causality and the notion of the self. In his Treatise of Human Nature (1739-1740), Hume argued that our beliefs in causation, the self, and even the external world are the results of habitual associations rather than logical deductions.

Empiricism significantly influenced the development of modern science and philosophy. It challenged traditional authorities and dogmas by prioritizing observable evidence and experience. The empiricist emphasis on experimentation and observation became foundational principles in scientific inquiry, shaping disciplines from physics to psychology. In contemporary philosophy, empiricism continues to inform debates in epistemology, philosophy of science, and philosophy of mind, highlighting the ongoing importance of sensory experience in human understanding.
