" 'Does this undefined 'quality' of yours exist in the things we observe?' they asked. "Or is it subjective, existing only in the observer?'…

…if Quality exists in the object, then you must explain just why scientific instruments are unable to detect it...if Quality is subjective, exiting only in the observer, then this quality is just a fancy name for whatever you like.

What Phaedrus had been presented with by the faculty of the English department of Montana State College was an ancient logical construct known as a dilemma. A dilemma, which is Greek for 'two premises,' has been likened to the front end of an angry and charging bull.

If he accepted the premise that Quality was objective, he was impaled on one horn of the dilemma. If he accepted the other premise that Quality was subjective, he was impaled on the other horn…

How could he say whether Quality was mind or matter when there was no logical clarity as to what was mind and what was matter in the first place?

And so: he rejected the left horn. Quality is not objective, he said. It doesn't reside in the material world.

Then: he rejected the right horn. Quality is not subjective, he said. It does not reside merely in the mind.

And finally: Phaedrus, following a path that to his knowledge had never been taken before in the history of Western thought, went straight between the horns of the subjectivity-objectivity dilemma and said quality is neither a part of mind, nor is it a part of matter. It is a third entity which is independent of the two.

He was heard along the corridors and up and down the stairs of Mantana Hall singing softly to himself... "
