The Early Foundations of Psychology
Psychology officially became the scientific study of the mind, behaviour and experience, but this didn't happen overnight. Key philosophers and scientists laid the groundwork centuries before psychology became its own subject.
René Descartes (1596-1650) came up with a revolutionary idea called Cartesian dualism - basically, he argued that your mind and body are completely separate things. His famous phrase "I think, therefore I am" suggests that thinking proves your existence, which was pretty mind-blowing for the 1600s.
John Locke (1632-1704) had a different take entirely. He proposed empiricism, arguing that you're born as a blank slate and everything you know comes through your senses and experiences. No inherited knowledge or instincts - just pure learning through life.
Charles Darwin (1809-1882) revolutionised how we think about behaviour with his evolutionary theory. He suggested that both human and animal behaviours evolved over time, with stronger, more adaptive traits surviving through "survival of the fittest."
Key Point: These early thinkers set up the fundamental debates in psychology - nature vs nurture, mind vs body, and how we acquire knowledge.
The breakthrough came when Wilhelm Wundt opened the first experimental psychology lab in Germany in 1879, making psychology a distinctive discipline. Meanwhile, Sigmund Freud was developing his ideas about the unconscious mind and psychoanalysis therapy in the 1900s, emphasising how hidden mental processes influence behaviour.
