ROBIN WILLIAMS—Come Inside My Mind treats Robin Williams’ explosive comedy as well as his darker side, but largely ignores the social circumstances in which he matured and worked. In the late 1960s and early 1970s, it was not possible to be in New York City and San Francisco and not absorb something of the epoch’s radicalism. The receding of that radical, free-spirited wave had consequences for artists like Williams, whether he was aware of them or not. He was somehow stranded, brilliantly isolated, attempting single-handedly through his routines to make up for the increasing coldness and selfishness of the times.
