Early-to-mid 20th century Europe and America (to the extent that America reflected aspects of European culture) is my spiritual home. The world of the new physics and the Vienna Circle. A world of artistic and literary ferment. Even much of the popular culture was not ephemeral (the Gershwin brothers for example).
And yet I know this world only by the traces it has left - books, paintings, films, songs; but, more importantly, by overlapping generations and manners of thought, speech and action that survived long enough for me to learn to love and respect them.
I don't know that book-learning is ever really enough to know a culture. One has to grow up in it - or at least to mix with those who did or, more doubtfully, to mix with those who mixed with those who did! That song comes to mind: I've danced with a man, who's danced with a girl, who's danced with the Prince of Wales...
When I was an undergraduate, many of the older academics spoke English with German or Hungarian accents and epitomized for me the archetypal European scholar. There were stories of encounters with famous names. An old colleague (and friend) was taught logic at Harvard by Willard Van Orman Quine and this mattered to me.
I recognize of course that much of this is idealized and even illusory and based on the same rather childish tendencies which drive teenagers to emulate pop-culture icons, or hang around hotel exits.
The difference is that my idols all checked out some time ago.
