Idealism (n.) is feared today like the foul fiend incarnate — and that anxiety, seen exactly, is anxiety in the face of philosophy.
Idealism (n.) that traces everything back to a consciousness defined only as 'un-Thing-like' is as naive as the most grossly militant realism.
Idealism (n.) is Platonism only after the idea becomes the perceptum of an ego; Plato himself was never an idealist but a 'realist'.
Idealism (n.) disempowers being philosophically; realism disempowers it without any philosophy.
Idealism (n.) and realism are metaphysics wavering between two extremes: the unconditionality of beingness and the unconditionality of beings.
Idealism (n.) may be outlawed by a dexterous partisan stroke of labeling, but that is no proof: to this day I know of no infallible decision that idealism is false, any more than that realism is true.
Idealism (n.) affords the only correct philosophical problematic if it means that Being can never be explained by entities — and in that sense Aristotle was no less an idealist than Kant.
