(William G. Pollard, Physicist and Christian....)

We marvel at their blindness for not seeing this .

(William S. Haymond, "Is Distance an Original...)

Psychical blindness is a condition in which there is a total absence of visual memory-images , a condition in which , for_example , one is unable to remember something just seen or to conjure_up a memory-picture of the visible appearance of a well-known friend in his absence .

It seems clear , when one takes into consideration the exceedingly defective eyesight of the patient ( we shall describe it in_detail in_connection_with our second question , the one concerning the psychical blindness of the patient ) , that he had to rely_on his sense_of_touch much more_than the usual portfolio maker and that consequently that faculty was most probably more sensitive to shape and size than that of a person with normal vision .

In what ways , then , did the patient 's psychical blindness manifest itself ?

(Arthur Miller, "The Prophecy," in The Best...)

There was an air of blindness in her gray eyes , the startled horse look that ultimately comes to some women who are_born at the end of an ancestral line long_since divorced from money-making and which , besides , has kept its estate intact .
