Gustav Fechner
Fechner, along with Wilhelm Wundt and Hermann von Helmholtz, is recognized as one of the founders of modern experimental psychology. His clearest contribution was the demonstration that because the mind was susceptible to measurement and mathematical treatment, psychology had the potential to become a quantified science. Theorists such as Immanuel Kant had long stated that this was impossible, and that therefore, a science of psychology was also impossible.
History of psychology
The first use of the term "psychology" is often attributed to the German scholastic philosopher Rudolf Göckel (1547–1628), often known under the Latin form Rodolphus Goclenius), who published the "Psychologia hoc est: de hominis perfectione, animo et imprimis ortu hujus…" in Marburg in 1590. However, the term seems to have been used more than six decades earlier by the Croatian humanist Marko Marulić (1450–1524) in the title of his Latin treatise, "Psichiologia de ratione animae humanae." Although the treatise itself has not been preserved, its title appears in a list of Marulic's works compiled by his younger contemporary, Franjo Bozicevic-Natalis in his "Vita Marci Maruli Spalatensis" (Krstić, 1964).
