Context

“Only the exceptional are allowed to have originality. The measure of difference between the average student and the genius is a measure of the absence of originality in the former. But this notion of mind in general is a fiction. How one person's abilities compare in quantity with those of another is none of the teacher's business. It is irrelevant to his work. What is required is that every individual shall have opportunities to employ his own powers in activities that have meaning. Mind, individual method, originality (these are convertible terms)” source
