In terms of cultural impact, few shows have been as successful or a more positive force for change than Star Trek​ and its sequel shows and movies. The writers and creators dreamed of a future without want, where petty bigotries and inconsequential differences no longer plague our species, at least not to the degree that they do now. Commander Spock served as a counterpoint to the brash and cocksure Kirk, and helped highlight both our foibles as emotional beings as well as the strength we can gain from them, in the form of love and compassion. Leonard Nimoy’s stentorian delivery and gentle good humor made what could have been a somewhat dry and even unpleasant character into someone to be loved and admired.

He was, and always shall be, our friend.

A life is like a garden. Perfect moments can be had, but not preserved, except in memory. LLAP
