Psychology
Psychology is the science of behavior and mind, including conscious and unconscious phenomena, as well as feeling and thought. It is an academic discipline of immense scope and diverse interests that, when taken together, seek an understanding of the emergent properties of brains, and all the variety of epiphenomena they manifest. As a social science it aims to understand individuals and groups by establishing general principles and researching specific cases.
Social
Living organisms including humans are social when they live collectively in interacting populations, whether they are aware of it, and whether the interaction is voluntary or involuntary.
Social Psychology
Social psychology is the study of how people's thoughts, feelings, and behaviors are influenced by the actual, imagined, or implied presence of others. In this definition, scientific refers to the empirical investigation using the scientific method. The terms thoughts, feelings, and behavior refer to psychological variables that can be measured in humans. The statement that others' presence may be imagined or implied suggests that humans are malleable to social influences even when alone, such as when watching television or following internalized cultural norms. Social psychologists typically explain human behavior as a result of the interaction of mental states and social situations.
Psychology
[Modern psychology] appears as the sickly offspring of average common sense when it is taken as what it professes to be—a science of the inner life. The entire achievements of the so-called science in this respect is outweighed by a single page of Goethe’s or of Jean Paul’s psychology; and it is impossible to evade the bitter truth which Novalis already has summed up, when he says that so-called psychology is one of those idols which have usurped the place in the sanctuary where true images of the gods should stand.
Ludwig Klages, The Science of Character, W. Johnston, trans., p. 16
Psychology
Unlike the physicist, the psychologist … investigates processes that belong to the same order — perception, learning, thinking — as those by which he conducts his investigation.
Morris R. Cohen, Reason and Nature (1953), p. 81

Psychology has a long past, but only a short history.
