I was in high school when I first saw a Modigliani painting. I was much taken by the long sensual lines, the muted earthy colors, and the strange contradiction of an abstracted nude that yet, somehow oozed life and sexual allure.

Remember the toy of pegs & holes? The game was to tap round pegs; square pegs; and triangular pegs into their proper holes? It taught us all, early on, to think of disparate things as components of categories.
