Philosophical Foundations and Early Psychology
Ever wonder why we think and behave the way we do? Ancient philosophers were asking these questions thousands of years ago. The Greeks laid groundwork that still influences psychology today. Plato recorded Socrates' advice to "Know Thyself"—a phrase that became a cornerstone of psychological inquiry.
Around 400 BCE, Democritus proposed that behavior results from interaction between body and mind, recognizing both biological and mental processes. Aristotle expanded these ideas, writing about sensation, personality, perception, emotions, and memory. As an advocate for empiricism, he emphasized learning through experimentation.
Psychology transformed in the 19th century when scientists applied the scientific method to philosophical concepts. Gustav Theodore Fechner demonstrated relationships between physical events and psychological sensations. Many consider Wilhelm Wundt the founder of psychology after establishing the first psychological laboratory in Germany (1879).
