The first issue serves as a first approach to the history of psychology as a scientific discipline, focusing on its purpose, method and general design. The second issue provides an overview of the history of modern psychology, the contributions of philosophy and natural sciences, functional interpretations of the adaptive mind as an instrument derived from the theory of Darwinian evolution and the first experimental developments arising from the Experimental Physiology, Psychophysiology and Psychophysics, developed in the eighteenth and nineteenth centuries, which form the prelude to modern scientific psychology. We intend thereby to provide a historical overview of the evolution of scientific and philosophical thought before the establishment of modern academic psychology.
