  • Francis Bacon

    Bacon contributed to the scientific approach to psychology and experimentation. He did studies on how each mind perceives certain events differently from one another. Francis Bacon also composed a book on his studies, called "Novum Organuum."
  • Rene Descartes

    Descartes was a French philosopher that wrote A Discourse on Method, and suggested that spirits were inside the brain (or nerves) that provided memories and reflexes. Descartes also disagreed with Aristotle's ideas, believing in innate ideas, that "the mind's being was entirely extinct from the body, and able to survive after death," (Myer's Psychology for AP, 3).
  • John Locke

    John Locke
    John Locke created the "theory of mind," which is considered today as the origin of the concepts of identity and self. He influenced several other well known thinkers such as Voltaire and Rousseau in the development of their work.
  • Dorothea Dix

    Dorothea Dix
    Dix advocated for more civilized treatments of mental patients in hospitals. Originally, people thought that psychological disorders could be beaten or shocked out of people. She helped organize institutions with the distribution of therapeutic drugs and treatment programs.
  • Charles Darwin

    Known for his biological advancements in evolution, Charles Darwin also contributed to the field of psychology. In Darwin's book "On the Origin of Species," he proposed natural selection, or the traits given to help one survive and reproduce. His theory developed the question of nature vs. nurture, and whether one is more dominant than the other, or if they coexisted together.
  • G. Stanley Hall
