> In short, the concepts of science--hitherto associated largely with the cosmic, the inorganic, the "mechanical"--were now applied to every phase of human experience and every manifestation of life... men sought for an underlying order and logic of events which would embrace more complex manifestations.
Sorry, that’s just silly, unless this was about events that happened way earlier than he was writing. Using the scientific method to study life goes back to the Enlightenment. Buffon and Linnaeus were doing it 2 centuries ago, more than a century before this was written. Da Vinci explicitly looked for inspiration in the way animals functioned to design machines and that was earlier still. There was nothing new, even at the time, about doing science about "every phase of human experience and every manifestation of life".
Well he is indeed discussing the early 20th century in that quote, but your point highlights exactly what he’s trying to say: he’s contrasting the previous zoological approach that treated humans as inert machines with inputs and outputs (~physiology, and arguably behavioral psychology) with the modern approach of ascribing reality to the objects of the mind (~cognitive psychology).
