It is clear that personal prejudice and moral persuasion percolate into one’s “intellectual” pursuits. It is equally clear that it is the structure, not necessarily the content that is most influential upon the reasoning of individuals.
I suppose a close analogy to this could be derived from music. Most composers become instantly recognizable given a certain number of previously experienced pieces. The cadence, the phraseology the progression of notes, etc.
The same can be said for everyone. It is the structure of our internal logic that most informs our opinion…we cannot bear to hear music from other sources. We are polite and exclaim that (x) type of music escapes our grasp…but what is occurring an emotional reaction to some hidden pleasure/pain generator.
All arguments that occur in reality are slaves to this “tin ear”.
