I have made my most memorable purchases on trips, as a transient. Property and possission belong to the tactical sphere. Collectors are people with a tactical instinct; their experience teaches them that when they capture a strange city, the smallest anitque shop can be a fortress, the most remote stationery store a key position… You should know that in saying this I fully realize that my discussion of the mental climate of collecting will confirm many of you in your conviction that this passion is behind the times, in your distrust of the collector type. Nothing is further from my mind than to shake either your conviction or your distrust. But one thing should be noted: the phenomenon of collecting loses its meaning as it loses its personal owner. Even though public collections may be less objectionable socially and more useful academcially than private collections, the objects get their due only in the latter. I do know that time is running out for the type that I am discussing here and have been representing before you a bit ex officio. But, as Hegel put it, only when it is dark does the owl of Minerva begin its flight. Only in extinction is the collector comprehended.
