It seems like an inherent part of the left-brain / right-brain dichotomy, where the hard sciences try to use clear definitions and numbers to narrow down the possibilities and theories into as small a set as possible (using their own discipline's set of technical terms bordering on a "secret language"), and the "soft" sciences seem to blur the distinctions and boundaries at every turn, because almost everything has a direct or indirect effect on practically everything else, and all of the definitions are subject to constant change and debate as social norms themselves change over time. The one set of sciences is primarily about facts and figures, the other more about feelings and relationships.
Personally, I'm more of a "hard science" person (electronics engineering technician), with a touch of artistic flair (bass player), although I have no clue how this relates to the days of the knights. Then again, I was in the Society for Creative Anachronism (SCA - featuring full armored medieval combat) briefly, so perhaps I could be called a "knight for a day", except that I didn't have much of a fief to support me (a few square yards of urban blight).
