Good science, bad philosophy

Behrendt's & Young's (B&Y's) persuasive scientific theory explains hallucinations, and is supported by a wide variety of psychological evidence, both normal and abnormal - unlike their philosophical thesis, Kantian idealism. I argue that the evidence cited by the authors in support of idealism actually favors realism. Fortunately, their scientific theory is separable from their philosophy, and is methodologically consistent with realism.
