Ants

Photography has generally been defended on the ground that it is useful, in the sense that the McCormick reaper and quinine have been useful. Excellent and persuasive arguments have been developed in this spirit; these are well known and need not be repeated here. It should be added however that some of the very best photography is useful only as juggling, theology, or pure mathematics is useful -- that is to say, useless, except as nourishment for the human spirit.
