Hass on the Muller-Lyer

It is not unusual to see writers use this illusion to conclude that perception is a merely subjective event: "The two lines appear to be different lengths, when objectively they are the same; therefore, perception is subjective appearance, which hides objective reality." This reasoning is specious, common though it may be. Just because one can construct (with a ruler) some numerically determinate figure that we perceive indeterminately, does not entail the ontological claim that fundamental reality is a collection of fully determinate objects and perception a mere subjective appearance.

Maybe some readers can help me with the foregoing passage.  So, I'm willing to entertain the view that this reasoning in the quotation is specious and that perception is not subjective appearance.

And, I agree that just because one can construct (with a ruler) some numerically determinate figure that we perceive indeterminately, does not entail the ontological claim that fundamental reality is a collection of fully determinate objects and that perception is a mere subjective appearance.

I also agree that just because one can construct (with a ruler) some numerically determinate figure that we perceive indeterminately, does not entail the ontological claim that fundamental reality is a collection of fully determinate objects.

But, I don't see how the view of perception is supposed to be linked to the theory of fundamental reality.  (I would have thought that all one needs is that appearance differs from reality. ) How is this supposed to work?  Honest question.
