Donald Judd spoke of a 'neutral' surface, but what is meant? Neutrality must involve some relationship (to other ways of painting, thinking?) He would have to include these in his work to establish the neutrality of that surface. He also used 'non' or 'not' - expressive - this is an early problem - a negative solution or - expression of new sense - which can help one into - what one has not known. 'Neutral' expresses an intention.
I believe in the immortality of the soul because I cannot conceive of an intelligent First Cause creating human beings through long process of evolution in this world only to destroy them.
