Sontag's Avidity

From David Rieff’s foreword to At the Same Time: Essays & Speeches, collected writings of his mother, Susan Sontag:

She was interested in everything. Indeed, if I had only one word with which to evoke her, it would be avidity. She wanted to experience everything, taste everything, go everywhere, do everything. Even travel, she once wrote, she conceived of as accumulation. And her apartment, which was a kind of reification of the contents of her head, was filled almost to bursting with an amazingly disparate collection of objects, prints, photographs, and, of course, books, endless books.
