Awkward 23 year-old dude, William James, in Brazil 1865. 

Functionalism, early movement in the study of psychology credited to James, denies the principle of introspection, which tends to investigate the inner workings of human thinking rather than understanding the biological processes of the human consciousness, says Wikipedia. I'm getting a lot of shade and attitude towards psychoanalysis and Freud in that mission statement. And who might counter, I'll add, why overlook what tremendous insights the inner workings of human thinking can tell us about biological processes? Foremost, sex. But also childhood development and neurosis and the promise of offering some relief to those suffering neurotic conditions through clinical psychoanalysis or a talking cure. Isn't sex or sexual reproduction one of the most basic and fundamental biological processes? Maybe your puritan modesty and laudably fierce commitment to individual privacy rights, Professor James, obstructs your view but it's the behavioralism, Skinner et al, that grew out of your prudish functionalism that, unfortunately, lends itself to applying surveillance and coercive mechanisms of social control to biological processes. In psychoanalysis we are trying to help liberate humans from a traumatizing and haunted past. In behavioralism they attempt to reduce the human subject to a rat in a cage and data collection, although I understand you cannot be blamed entirely for any of that. But maybe a little?
