The problem for any idealism remains that of showing in a non-question-begging way how you get the objective out of the subjective, in other words the exact opposite of the so-called 'hard problem'. Idealists might claim that no such problem exists because of something like imagination, the projecting of a world by the dreaming subject, but even if the introduction of this objective power of the subject were accepted, this only produces a weak, shadowy form of objectivity. You might ask, how does an objectivity worthy of the 'hard problem' being posed arise? Logic or a 'calculus of distinctions' fails in the same way. You need an equation (or a poem) written in the terms of subjective reality whose solution can only be an objective reality.
