Quotations
Only recently […] have biographies incorporated an analysis of an individual's sexuality, not in some vulgar Freudian sense, but as helping to explain someone's internal sense of differentness or specialness — or, as I suspect in Lowenstein's case, aloneness — that becomes a springboard for a special life.
