“Towns are like people. Old ones often have character, the new ones are interchangeable.”

is an interesting and broadening eternal question, but one which, if pursued exclusively, results only in an endless parade of trivia and fashion, the silt of tomorrow. I would like, instead, to be concerned with the question "What is best?," a question which cuts deeply rather than broadly, a question whose answers tend to move the silt downstream. There are eras of human history in which the channels of thought have been too deeply cut and no change was possible, and nothing new ever happened, and "best" was a matter of dogma, but that is not the situation now. Now the stream of our common consciousness seems to be obliterating its own banks, losing its central direction and purpose, flooding the lowlands, disconnecting and isolating the highlands and to no particular purpose other than the wasteful fulfillment of its own internal momentum. Some channel deepening seems called for.

As quoted in The Quotable Woman (1978) by Elaine T Partnow, p. 226. "When men destroy their old gods they will find new ones to take their place" has sometimes been quoted as her original statement, though she states that she herself is quoting an abbot.
